Zell is a consummate martial artist and his skills are unsurpassed in Garden. Zell never backs down from a challenge and stands up for what he believes is right. He is energetic, loud, overconfident in his abilities, but tends to not think things through and overreact to being teased. He attempts to befriend everyone he meets. He is often in trouble with either the Disciplinary Committee or the Garden Faculty for running through the halls, or riding T-Boards on Balamb Garden premises, but despite this, Zell is a model pupil with an interest in world events.
Zell has a close relationship with his mother and is a prominent figure among Balamb Town, as pretty much everyone there knows him. Zell admires his grandfather, who used to be a soldier, and aspires to follow in his footsteps. Zell loves hot dogs, but due to high demand there are never any left for him by the time he shows up.
