DRW Brandon Whittaker

 is a Dead Rising 2 psychopath. He literally rips into Chuck with a hooked shard of glass with what seems to be inhuman speed. He also jumps into toilet stalls, teleporting to another stall near Chuck. Never take other survivers into the fight with you as Brandon will kill them very quickly.

Trivia

 * In Valve's popular zombie game, Left 4 Dead 2, a gunshop owner is named Wittaker. He instructs the survivors to fetch him Cola, if they want him to clear the way to the mall.
