With The Sarah Connor Chronicles arriving a little after the New Year, one must begin studying up on all their Terminator facts. Fortunately for us, there is now a site that allows one to learn from and contribute to the Connor universe.
Hardened endo-skeleton designed to withstand attack from other Terminators ability to inject nanobots (presumably an extension of the Mimetic Poly-Alloy), concealed weaponry including.. Diamond Tipped Circular Saw Plasma Cannon Flame Thrower.
Design flaws: Shapeshifting is limited due to the internal endoskeleton denying it abilities that were available to the T-1000 as flattening totally into the floor.
That is only a sample of what you can learn about the T-X and every other Terminator off the production line at Sarah Connor Chronicles Wiki. The site looks relatively new so, if you are a die hard Terminator fan, I'm sure you'll find areas in need of your contributions.
The Sarah Connor Chronicles premieres Monday, January 14th on Fox.
