This is about describing all of the terminator models and skynets existence. We will start with what is skynet? Well skynet is a super computer ( advanced AI) that was created by humans at cyberdyne research facility. It began to learn at a geometric rate and started to see humans as a threat to its survival. It decided to take over the whole network sector, power plants, and factories. Humans panicked and tried to shutdown it  down because it was becoming self aware and needed to be stopped. 

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.                       

                    

                

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 uraniun rounds capable of firing 3000 rounds per minute.      

3. The T 4 is a HK tank deployed by skynet during the future war.      

    

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 suit.

T-H also known as terminator hybrid or theta is a human been transformed into a cybernetic organism. His body was replaced by a hyper alloy combat chassis  but still kept his organs, heart, teeth and brain. The most notable character that given his body up to skynet was Marcus Wright. He possessed strength on par with a T-800 terminator and can toss around.

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. Thomas Parnell and Marcus Wright were canidites to the Project Angel orchistrated by Dr Serena Kogan. Reason why the T-5000 is a powerful terminator is because its the representation of skynets core and is housed in it. 

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.   

8. The T-400 endo is nicknamed clanker or faker by resistance and is a humanoid hunter killer invented during initial tests to mimic human anatomy. They did serve as skynets personal bodyguards but there no match for modern weapons of nay caliber and can easily be destroyed by an uzi 9mm submachine gun. They would capture humans to send them to skynet for slavery or termination. They are made of steel rather then hyperalloys and more primitive technologies. They are pretty strong able to lift an excess of 1000lbs and smash through concrete and reinforced walls plus kill humans face to face in combat. They are very clunky units with weaknesses such as there red optical sensor and are slow.

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 which is very powerful. They were fast and strong, able to lift 5 times there own weight. There cpu was improved and a working jaw. Standing almost 6 ft tall and weighing 800lbs.  

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 terminator which has more armor plates on its combat chassis and durability then a T-800 and carries a plasma rifle.
