Bolo is described as a "block-head hero for hire". Supposedly, he springs to life when he has a chance to fight, but he's often left behind during Shantae's adventures and has yet to show off these skills.

Bolo is frequently trying to seduce girls or spy on them, including Risky Boots in the first game, but fails every time. He's shown to be jealous of Bran-Son's popularity. However, he has a more argumentative brother-sister relationship with Shantae. Bolo serves as a sparring-partner and punching bag for Shantae, and as an assistant for Mimic. Bolo is the one who taught Shantae her Fighter Moves.
