Fury
As a Brute engages in combat, it unleashes his Fury. The longer he remains in combat, attacking and being attacked, the more damage he deals.
A brute's damage value increases by one for every five Wound Points taken.
Build
A brute uses Powers skill and Super schticks. The obvious power choices are Abysmal Spines, Blast (Melee), Attribute Enhancement, and Attribute Boost.
For defenses, use power like Armor, Displacement, or Damage Resistance and add Elemental Aura for extra fun.
The Taunt pulp schtick and Intimidation skill are highly useful too.
