Like most Pigmask enemies, they can fire beams and perform bum rush attacks. Majors can also utilize a series of joint strikes that may cause numbness, as well as a sticky time bomb that explodes a turn later for moderate damage to a single target. The ones faced in Chapter 7 can additionally call for help, or run away while throwing a bomb that damages the entire party. Their battle theme is More Audacious March.

- Its battle sound is Battle Sound 19 which falls under Code Numbers 493 for regular attack, 494 for Smaaaash! and 495 for Miss.
