Im going to list all the terminator models that skynet has been using since judgement day began and before it.
1. T-1 is a battlefield robot also known as ground assault vehicle. Its a hunter killer tank and its bipedal meaning it ran on hydraulics and trailing links. It is developed and obtained by cyberdyne research systems. Its designed to take out battlefields of soldiers and has good weaponary. Armed with plasma weaponary. Its not meant to resemble a human only to deliver maximum firepower to its foes. To destroy these big machines, a rocket launcher or canister bombs can do the trick. Most modern weapons wouldnt be able to scratch its hull. John Connor has reprogrammed one and used it against skynet.
2. T-5 and T1-7 are warrior robots and a variation of the T-1 tank. They are earlier model terminators developed by cyberdyne research systems. They are armed with depleted uranium rounds capable of firing 3000 rounds per minute. There cpu is not really impressive other then being a targeting system. Not as advanced as new models.
3. The T 4 is a HK tank deployed by skynet during the future war. Not is known about this model other then its a smaller version of a HK tank.
4. T7T tetrapod is also known as the spider by the resistance and a quadruped hunter killer designed to protect key points of interest for skynet. It has a crab like body, two twin machine guns and 4 arthropod legs. It has one red eye and battery packs for its power supply. There weakness is the battery packs from behind and there red eye. If attacking there red eye, it will only deactivate them for a short period before its running back up again. If constantly hit there battery packs it will shutdown and die.
6. T-5000 terminator is a variant to the TH terminator and has the most advanced technology. It has the ability to simultanously take control of other terminators by synchronization via sattelite connection.
6.T-47 is a large bipedal hunter killer utilized by skynet and is equipped with two rocket launchers plus two armed mounted gatling guns. When taking alot of damage it will shutdown and a few sec to reboot. 
7. T-70 is built from cyberdyne and is one of the series of terminators. Its the first terminator with a humanoid form and has a gatling gun and a motion tracker.
9. T-500: T-500 is a humanoid hunter killer upgraded and more enhanced then the T-400 terminator includes a battle chassis and the weapons are synchronzied into the AI for a more dangerous threat.
10. T-600 series terminators were mass produced by skynet and had latex skin which resistance fighters could spot them easy. They had a combat endoskeleton made of titanium alloy. They are fast and strong, able to lift 5 times there own weight and can punch through concrete without sustaining any damage to there servos. There cpu was improved and a working jaw. They can run at a max speed of 46 mph but the servos will glitch or malfunction due to the applied pressure. Most modern weapons such as the uzi or m16 wouldnt really able to penetrate its armor. Plasma weapons, pipe bombs or traps will either disintegrate it or damage it severely. The were built to be pretty heavy but can still run pretty fast.
11. T-700 is an early infiltrator series which was the stepping stone between the T-600 and T -800 terminator. They can be easily incapitated by contemporary fire and from a stab in the back of the neck. 
12. T-720 is a heavy termintaor which has more armor plates on its combat chassis and durability then a T-800 and carries a plasma rifle. 
13. T-800 was the first cybernetic organism with living tissue over a hyperalloy endoskeleton. It was the first successful infiltrator by skynet to breach resistance defenses. It has a neural net processor also called a learning computer. It has of the most powerful processor ever built since its able to store multiple data base files and extensive training data base files to making it a more effecient killer as its updated modules can come from other terminator models. Its micro processed controlled triple armored combat chassis with frictonless bearing in its joints. Powered by a nuclear power cell. It is 20 percent lighter and 40 percent stronger then a T-600 and can run up to 22 mph. It has a triple armored combat chassis and can shrug off most contemporary weapons. Its cpu can be set on read write mode or read only mode. Most weapons couldnt put a dent in its chassis so plasma weapons, pipe bombs , and 50 cal bullets can penetrate it and mostly destroy it.
14. The T-850 is a series of the T-800 terminator powered by two hydrogen fuel cells and is
resistant to plasma attacks. It is more battle hardened then a T-800. It can also be reprogrammed by the resistance as theres a port within its skull where its cpu lies. Its able to repair itself and reroute its systems if damaged. They dont have any nerve endings like a human has but they can sense injury damages within there HUD. This model is very hard to kill since it has more resistances then its predecessor the T800. Even first generation plasma rifles have little effect on its chassis unless its a plasma rifle.
15. T-888: T-888 is a successor to the T-800 and is made to be faster, stronger, and more resistant to damage. When knocked offline, it can reboot in two minutes. It also has a flexible endoskeleton capable of functioning even if its head is separated from the torso. Its skin is easier to remove for better infiltration techniques like a hidden knife or plasma. These models are identical to the predecessor the t 800 in terms of design. T888s have a different hud and is a little more agile. It can take a beating by most contemporary weapons except weapons such as gen 1 or 2 plasma and uranium shells can destroy it.
16. T-900 is the successor to the T-850 and the predecessor to the TX. The 900 was the first anti terminator designed for combat to be able to fight against more advanced terminators. Its power source is a small fusion reactor. Its body can glow in different colors. Its more durable, faster, and stronger then previous models. It can take control of animals such as dogs or other things.
17. T950 is a variant of the T-900 and is similar to the T800 as its made of a hyper alloy endoskeleton covered in living tissue. Also has built in weapon systems compared to older models. It can take extreme amounts of damage and can easily punch through steel or concrete. As of the T-1000, it only has mimetic polyalloy just to cover the arms. It can operate even when its head is off. The only way to destroy it would be complete destruction of its body and head.
18. TX terminator also called terminatrix is an advanced model made with mimetic polyalloy and originating from a T-900. It is protected by a malleable ceramic titanium armor. Its able to control other machines by nano technological transjector. It is virtually unstoppable on the battlefield able to crush other models with its thighs which are greater then an industrial hydraulic press and bite with so much amount of force as to break almost anything including titanium. It has onboard weaponary such as a plasma baster, cannon, flamethrower, etc. Its very hard to kill since it doesnt have much weaknesses other then magnetic field or something to break its structure apart.
19. T-1000 is an advanced prototype produced by skynet and is autonomous unlike other models who were not. Its able to shape shift such as change faces, make hook weapons and even become a floor. It can only replicate objects or forms to its size. It has a liquid molecular brain that is mimetic polyalloy. Its able to reason ,become self aware, and sense of humor by this brain. Its able to recontruct itself if and can heal really rapidly and travel at fast speeds. Certain chemical hazards or heats are known to cause severe glitches in its system even killing it permanently. Skynet didnt mass produce it because it was afraid it would go rogue. Its almost unstoppable but acid can permanently destroy it, pretty much anything thats corrosive.
20. T-XA Its made of mimetic polyalloy the same as a T-1000 only far more stronger and durable is almost invincible to other models being able to crush a T-800 with ease or take direct hits from plasma shots before being destroyed. In its human form, its 8ft tall and is able to split itself into several units for the purpose of stealth. The most terrifying thing about this model is that its able to control humans by putting parts of its elements inside of the hosts brains and controlling them. It can take an absolute beating such as plasma rounds etc. 
21. T-Meg is also called the T-1000000 and is made of mimetic poly alloy. Its a gigantic spider hunter killer. Its main priority is to protect skynets central core from invaders.
22. T-infinity is a temporal terminator created by skynet to make sure the timelines are balanced and not out of wack. It has time displacement equipment engineered into it so it can relocate anytime it wants to. Its stronger and more durable then a T-800. It has many weaknesses such as stealth attacks, EMP grenades, close combat, and other various forms of weapons. It also has energy blade to defend itself which makes it pretty effective in situations and has onboard weaponary. 
23. T-3000 is a really advanced model that infects humans with machine phase matter that transforms it on a cellular level into billions of nano machines that rewrites its DNA. The only successful human to survive the process was known other then John Connor. The machine phase matter that holds the T-3000 chassis is held together by a magnestic field and can make stabbing weapons, etc. It also grants the individual with regenerative abilities, and impersonation skills. It is extremely hard to kill since it can take massive damage and recover more quickly then a T-1000 can. Its also immune to electocution.
24. T-4800 is skynet who technically was the advanced AI that became self aware and started to take control of power plants, factories, networks, etc. It was the one who set off the nuclear holocaust that killed 7 billion humans and started judgement day. It used blueprints, test models, etc from cyberdyne systems to produce automated terminators and other hardware to ensure it survives against the resistance.
25. T-5000 is an advanced model terminator series produced by skynet after the end of the future war. Skynet transferred its conciousness into the unit so it could go back to the original timeline and infect John Conner turning him into a T-3000 cyborg. It has the ability to infect humans on a cellular level.
26. T-8000 is goliath terminator developed and built by skynet in a huge facility.
27. Sky-1 is the physical embodiment of skynet and has onboard weaponary inside its body to combat opponents. 
28. T-90 is a type of humanoid hunter killer that is similar to the T-800 except it has no living tissue. Its design was important for creation of later terminator models such as the T-101 terminator. Skynet made and produced these units in mass production for the future war after judgement day happened. They are superhumanly strong and durable which are able to crush a human easily or bend steel with ease. They can even function even after their limbs are destroyed and other hazards. There weaknesses is electricity, plasma weapons, and explosives that can cause severe damage to it or completely blow it up.
29. T-101 is a humanoid hunter killer with living tissue over metal endoskeleton.
30. I-950 is human captive or defector that has been cybernetically enhanced from implants that skynet produced and can control their actions by pain centers in the brain. There extremely versatile and strong capable of breaking concrete or other hard materials with ease. They also carry onboard weaponary inside of them and other tech within their abdomen. Decapitation will not stop them unless the complete destruction of their whole body plus brain is destroyed. They can even hold multiple data bases for almost any situation.
31. T-300 is a stealth terminator made from ceramic. They have advanced software built into them that can mimic different captives personalities and override them even. There endoskeleton mimics human weight, physiology, and has organ systems too. It can wireless connect to skynet and other terminators if need be. They are stronger then a T-888, faster, and more durable. Skynet doesnt mass produce them since they can also go rogue and only need to build them for stealth missions.
32. T-900 is designed by skynet that has advanced software for infiltration that makes it believe it is a human similar to a T-300 terminator. It is made of hyperalloy much the same as the T800 series but with coltan. Its similar to most terminator models such as if its injured it can repair itself. Its power source is a nuclear power cell and can reboot itself in about 120 seconds. Its HUD is different then other models since its not red or blue its a head on display. Its able to mimic certain emotion and other infiltration techniques in order to achieve its mission or from being terminated. Its able to consume food and is able to feel into the environment. Can sustain alot of damage.
33. New Terminator: New terminator is an advanced infiltrator developed from a T-800 capable of mimicry, lying, cheating etc as a human can and blend in with the rest of society. Each new terminator is unique with its own special features.
34. Hunter Killer: Hunter killer also known as HK in terminator is an artificially advanced autonomous war machine that is robot and android alike desgined and built in automated factories. They are in almost every design that skynet creates or manufactures such as the tank and aircraft plus terminaor series.
35. T-72 is known as spiderdog and is a skynet terminator series and a quadruped hunter killer armed with a plasma cannon which can also be changed into a flamethrower or a missile launcher. 
36. Spider tank is a non humanoid hunter killer that is an assault bipedal walking unit that is double the height of a human. It has two arms each equipped with a forward facing and rear facing plasma cannon. Its stored in an HK aerial hunter killer.
37. HK spider tank is a quadruped walking style non humanoid hunter killer developed by skynet. Its legs are that of a spider and uses them for transportation. Its capable of leaping into the air and attacking the resistance fighters for capture or termination. Its weapons are two plasma turrets and a shield generator for protection. 
38. Dire wolf is a canine dog terminator created by skynet. Its as big as an HK-aerial and is ferocious capable of defeating advanced models. 
39. Big bad wolf is a wolf type infiltrator with living tissue over metal endoskeleton that created by skynet to hunt down humans and dogs. 
40. 1825.M is a human cyborg. A guy named Dudley was an ER trauma surgeon who later on after judgement day joined the resistance and became a combat medic. He got blown up by skynet heavy artillery that severely injured him. He became skynets first prisoner of war. It took alot of surgeries to reconstruct his body and his brain. Skynet used him as a mobile field unit for the maintainence of the T-800 terminators. His primary function was he was able to heal his tissue and help other terminators do the same so that they will remain undetected by the resistance. Skynet put cybernetic implants in part of his brain since some of it was injured. He was struggling against the skynet components and eventually self terminated himself. 
41. The harvester is a massive non humanoid bipedal unit that was produced by skynet sometime before 2016. Its main function is to capture humans for the machines so they can study there stem cells to make real skin for the T-800 terminators. It calls in a transport located near it to put the humans in and then it goes back to skynet to drop them off. It has a large plasma cannon on the back left of its body that can destroy almost anything with one hit. It also stores two moto terminators in case any humans get away. Its power source is either a diesel power plant or a diesel generator. 
42. Terminator Aurora T808 is a female terminator that is a test model who is seductively beautiful with pink lips, body, etc. For a machine she shows unusual behaviour such as flirting with humans then killing them with a whip of a belt to pin them to the wall to kill them slowly while she starts kissing as they die. She likes to manipulate humans to see how long they can survive for then once skynet gains enough information from it its deactivated. The terminator model has fast reflexes able to stop an overhead swing from a metal piper and redirect it back to its user. It is not a combat unit like the t800 series but nonetheless it does its part. Aurora was destroyed in a plasma grenade explosion during the raid of skynet in 2041. The T808 Aurora was designed to be a probationary test unit. It misinterpreted human psychology alot and was deemed unstable, cruel or sadistic. Much of its cpu power was directed towards torture techniques and was weak in terms of combat capabilities making her useless on the battlefield. 
43. The T 660 terminator is a huge advancement from the T 600 also known as ragdoll which skynet was able to make it more lighter by reducing its size to a more of a human look. It has a light titanium chassis so more manufverable and not as heavy as a T 800. It also upgraded its memory and processor speed. It blends in with the human crowd by dressing very poorly but discriminately so it can be able to better infiltrate the resistance camps etc. Its skin is more tear resistant so its a little more stealthy. Its facial features such as the mouth and mask is expressionless as well as its jaw. It has crystal beads for eyes It can be destroyed with contemporary weapons, etc so its not that durable as other terminators such as the T700 and 800 models.
44. T-Rip( resistance infiltrator prototype) is a series 800 terminator that was manufactured in skynet central in 2018. It was the first infiltrator to speak when its flesh was removed. It was also the first to have no signs of damage when its flesh was destroyed and operating at full capacity. It is said in a novel called trial by fire that this terminator was an updated T 700 with synthetic skin. Its a very durable machine that can pretty much go through almost anything with minimal to moderate damage. It is made out of coltan which is a metal compound that can withstand about 4000 degrees fairenheit. Contemporary weapons or even a grenade launcher doesnt really affect it that much as it got up pretty quickly. It can be brought down by explosive rounds such as uranium shells, thermite, rocket launcher, and phased plasma weapons. Its very hard to destroy unless given enough force with some blunt object or bomb would do the trick. It is a pretty good hunter when its analyzing its prey. Its heads-up display looks more clear and simple then the original t 800s with not much calibrations going on. 
45. T690 also known as alpha prototype and is a series 600 terminator. Its getting close to its T 700 terminator counterparts with its advancements.These abominations use the remains of dead subjects to try and remain unseen from resistance. They are stitched and put in nutrient baths to sustain there flesh sheath. It was the first generation light titanium frame and had a skin called hypodermis such as muscle, necrotic skin, fat etc from various donors. They go on infiltration missions while concealing themselves by using faces from donors. Dogs and humans could spot them pretty easily. They ultimately were failed prototypes and just were the key to more advancements in upcoming series of terminators or models.
46. John Connor is the leader of the resistance and was responsible for uniting the human survivors against skynet. Was born feb 28, 1985 by Sarah Connor his mother. He taught the humans how to fight such as invading skynet camps, learning how to shoot, espionage, etc. Skynet has sent many terminators via time displacement equipment to stop him but time and time again has proven unsuccessful. John grew up as a rebel kid after the destruction of cyberdyne and the original terminator. Much of his life was in skeptcism and from delusions of stories about his mother. He lived in a place called suburbia and didnt really do good there.
47. Moto terminators are automated motorcycles and produced by skynet around the year 2018.Its main purpose is to hunt down humans. They can travel at very fast speeds and have red sensors and plasma emitters on each side.. They are deployed by the harvester and to easily capture humans easier. They have a good tracking feature where they can analyze trajectories and debris as well as slow motion making them able to handle anything that comes its way. It can be hacked by plugging a usb port into the frame to control its AI.
