Few know of Shockwave's secret weapon, and he has killed to keep it that way. Shockwave has always enjoyed the glory of being outnumbered and coming out on top, and has a reputation for doing so. He doesn't always do it on his own though. Back on Cybertron, Tremor often lurked in the shadows, causing distractions and waiting to get a cheap shot kill on one of Shockwave's opponents. The ruthless one eyed decepticon has been known to take out entire combiner teams by himself, but when they combine, Shockwave sometimes needs a little extra firepower to take them down. That's when Tremor would come zipping out of hiding and attach to his master as an ion overload discharge cannon powerful enough to take down a war cruiser. When attached to Shockwave in tank mode, Tremor is capable of fully automatic fire. No living thing has ever survived a direct hit from this deadly Decepticon Targetmaster.
