Bio
It would be easy to dismiss Onslaught as a brutish thug… and maybe he is… but to him his greatest weapon is not his photon missiles or his sonic stun gun but his amazing tactical mind.
The key to victory is planning, and Onslaught executes his strategies with exacting and dispassionate logic. It's only when things don't go to plan that he gets frustrated and lashes out.
Which, admittedly, is often.
