A bruiser is a brawler that became much bigger, stronger and generally more powerful, able to break bones with a single punch. With a snatch a bruiser can grapple an enemy and just a squeeze of their muscular arms they can break the enemies back and even kill, this raw strength belies their speed, able to land a dozen devastating blows before the enemy can react. Free of the restraint of armour the bruiser take on any number of foes, even if they armed.
Bruisers love showing of their strength, engaging in contests wherever possible, eager to show up how much they can lift or break with one punch. This leads to them joining parties whenever asked, as much as the challenge of the unknown and the possible heroic deeds they can complete. In battle they use this to goad the enemy into thinking they can best them one on one, much to their folly.
