Berserker is a seething ball of destructive energy, his lust for violence constant and irrepressible. Anyone and anything that gets in his way is torn to shreds, leading his allies and enemies alike to give him as wide a berth as possible.
Berserker is absolutely insane, even for a Decepticon! By some miracle, the humans captured him and he's been constantly struggling against his restraints, spitting out the most graphic threats imaginable, which have led to stronger restraints, which make Berserker even more angry...and the cycle continues. Naturally, Megatron wants this maniac back in his ranks, but he knows it's a tall order.
