Beware of the man who has nothing left to lose. Codename is a Mario lookalike who was part of the Otherworld group, having lost the other 2 key members.
Through many, many deals, he's been able to get with a group that he leads. His goal? Defeat Mario and anybody who associates with him. He's tried this before, but that's the reason he doesn't look too great.
FUN FACTS
Codename spent most of his time in places that no one would find him when he wasn't on the move. Most notably, Tally's Forest.
It's unsure of how Codename got MX to co-operate with him.
Codename was the only one who was near the success of the destruction of creation. Maybe in another timeline, that may have happened...
Codename calls himself that "because that's all the leader ever called him".
