Ultraking

Ultraking was one of the people directly in charge of Crocodile's casino in Rainbase.

Appearance
Ultraking is an average sized man, with wild white hair that resembles a crown. He has a tiny bit of hair on his upper lip and sports a black suit over a purple shirt and red bowtie.

Personality
Ultraking seems to be a relatively calm person, since he didn't freak out when the Straw Hat Pirates entered his casino and simply called for security. He does, however, get quite apoligetic to Miss All Sunday, who is the manager of the casino, when Luffy defeats the Koala Mercenaries.

Abilities and Powers
He was able to run a successful casino for a long while and had the jurisdiction to call on the Koala Brothers for help until it was shut down due to the Baroque Works incident.

Past
At some point, Ultraking met and was trusted by Crocodile to take charge and run the Rainbase casino. He was given the position of assistant-manager, while the manager position was given to Miss All Sunday

Alabasta Arc
When Luffy and his crew barged into his casino, Ultraking ordered the Koala Brothers, the casino's security, to apprehend the pirates. After they were defeated, he deeply apologized to Miss All Sunday. She told him to lead the pirates into the VIP Room, which confused Ultraking, but he did so when she said it was Crocodile's orders. He and his staff then led them, along with Smoker, to the VIP Room, where they were locked in cage to drown. His fate, after the casino stayed closed, is unknown at the moment.
