Oninun

The Master of Clones

After performing an action, he can summon clones to repeat said action as many times as he wants. Oninun was once a disciple of Carlos. However, Oninun felt Carlos wasn't teaching him good enough and went into the mountains to train alone.

He's not a bad guy, just not entirely on Carlos' side. He doesn't oppose Carlos, in fact they have somewhat of a friendly rivalry between them. Carlos is usually the one to "win" in that situation though.
