Infinite is a black jackal. Arrogant, has pride and sees himself as a powerful foe. Denies being weak. Nearly fearless, he was never fearless until he met Shadow. Loud boisterous, rough. Used to be a mercenary where he was the boss of the Jackal Squad. However he claims the Jackal Squad got destroyed. Once he gained the Phantom Ruby he became darker and more lethal. Cold, subdued, menacing, with his speech being formal, eloquent and theatrical. Confident. Strong sense of superiority.
