The devices collectively known as T.E.C.H. (Transformers Electronic Combat Hardware) are human electronic items that use Cybertronian technology to convert into weaponry.

The T.E.C.H. subline, like the Real Gear Robots, is a series of "role-play" toys. However, unlike the Real Gears, T.E.C.H. toys transform into unliving weapons, and feature electronic light/sound and spring-loaded action gimmicks.
