Rattrap is a evil Maximal in the Shattered Beasts universe.
"Uh, yeah sure thing, I'll just put it back here."
-Rattrap after being caught with Tigatron's stuff.
Rattrap is sneaky and generally untrustworthy. A thief and narcissist this cowardly rodent is near useless in everthing, he hides in battle, dosen't report for gaurd duty, and tries to steal anything and everything. Due to his unique "initiation" into the Maximal crew he is always being tortured with crackling energy. Optimus refuses to give him repairs thinking the vermin's displeasure amusing.
