Zero (Digimon Adventure V-Tamer 01)

Zeromaru, often shortened to Zero, is a fictional character from the manga series Digimon Adventure V-Tamer 01 and Digimon Xros Wars. Unlike most Digimon in the franchise, Zero has a name and is not referred to by his species.

Description
Zeromaru shares many of the personality traits belonging to his human partner Taichi—he is very strong willed, but somewhat fool-hardy, and hates to be underestimated. He acknowledges the fact that he can't do everything on his own, but is determined to prove his strength nonetheless. Throughout the V-Tamer 01 series, he fights against many powerful Digimon, and often wins only because of Taichi's tactics.

Attacks:
 * V-Breath Arrow: Veedramon's V-Nova Blast; Shoots out a V-shaped heat beam that can burn an enemy to crisp in seconds.
 * V-Breath Arrow MAX: Concentrates his energy into a giant V-Breath Arrow.
 * Hammer Attack: Powers up his fist and launches a punch at the enemy.
 * Magnum Punch: Punches an enemy.

Development
Zeromaru was created by Hiroshi Izawa. It was originally intended to be a winged Rookie Digimon that was nicknamed V.V.. This name was later used for Rina Shinomiya's Veevee.
