Maji usually fights using his master's inventions. He used a giant fan to blow away the Going Merry. While chasing Roronoa Zoro and Nami on a track, he rode on a fast moving bike with a skull figurehead, which had a long and sharp tongue sticking out, acting as a piercing ram. The bike also contains buzzsaws, though Zoro easily blocked them. As something seemingly unnecessary, there were horns and jukebox on the back that make rather loud fanfare when moving.
Maji bears some resemblance to Bartolomeo, as both tend to speak in a vulgar manner, wear jackets while bare-chested with tattoos showing on their chests, and have spiked hair as well as an overall punk appearance.
