Jesus Burgess

Jesus Burgess (ジーザス･バージェス, Jīzasu Bājesu), nicknamed "The Champion", claims himself a champion because he stands on top of buildings and challenges random people to fights. He appears to be based off of Mexican wrestlers, as both his name and face mask are Spanish in origin. He is extremely strong, and fought Ace by throwing a building on him. He has also shown to be quite level-minded and serious, as he berated Blackbeard for his easy-going attitude after the crew's failure to capture Luffy. He also appears to have similar characteristics to Franky as he tends to lift his arms and flex his muscles even when not necessary. He is the Helmsman of the Blackbeard Pirates.

Mock Town
He was first seen bending over a defeated man complaining about his strength. Another man then noted it and asked if he knew that he had defeated a man from Roshio's crew. Later, after Luffy had taken one of Doc Q's apples, he was seen standing on top of a building yelling out for decent challenge.

After Bellamy was defeated by Luffy he met up with his crew and asked about Lafitte and why he wasn't there. When their raft was destroyed by the Knock Up Stream he complained about his captain's easy going attitude towards their failure.

Banaro Island
After Ace and Van Auger attacked one another he was quick to throw a building at Ace that was easily destroyed. Later on he alongside the other crew members witnessed the fight between Blackbeard and Ace, but not before moving to a much safer location, where he and Auger had to comically pull the very sick Doc Q, along with his horse

Translation and Dub Issues
Its presumed the renaming "G.Zass" is due to the religious link from the name "Jesus", similar to the renaming of "Mr. Satan" from Dragon Ball Z to "Hercule".

Trivia

 * His name is perhaps based on that of real life pirate, Samuel Burgess.
