Brawl

Noisy, irritates all nearby. Hair-trigger temper, blusteringly belligerent... a terrifyingly effective warrior. Enormously strong, resistant to most conventional artillery. As tank, goes 45 mph, range 600 miles. Turret-mounted gun shoots 200 lbs. TNT-equivalent shells, twin sonic cannon shoots powerful, ear-splitting 300-decibel bursts of concentrated sound energy in stereo. In robot mode, has 10-Megawatt electron gun.
