Sanjuan Wolf

San Juan Wolf is a colossal giant who is a member of the Blackbeard Pirates. Known as "Colossal Battleship" for his size, he was originally one of the legendary criminals who was given a life sentence in Level 6 of Impel Down, where their crimes were so atrocious they were effectively erased from history itself. He was initially mentioned briefly by Emporio Ivankov.

Appearance
San Juan is an unbelievably-enormous giant, towering over the largest beings known to date like Oars or Oars Jr. In fact, he is so big that he appears to be roughly the same size as Marine Headquarters at Marineford and is thus the biggest known giant to date. His head is shaped like an Onigiri, and his facial features include round eyes with dark lining around them, along with mark-like eye-lashes, similar to those found on Franky's, that points downwards.

Personality
Despite being known for committing crimes that caused his existence to be erased from history, he seems to have a playful attitude, as seen when commenting that he was found when he was trying to hide behind Marine Headquarters at Marineford. He is also quite shy, as he acts scared when people realize who he is and continues hiding while the rest of the crew fights Whitebeard.Unlike his shy nature, San Juan Wolf shown a much more sinister impression while he was imprisoned, watching Magellan taking Ace to custody silently with a devilish grin on his face.

Abilities and Powers
His abilities have not yet been shown, but he was powerful enough to be contained in Level 6 of Impel Down when caught by the World Government. As a giant, he shares their attributes, including Super Human Strength, though to what degree is unknown.

Imprisonment in Impel Down
San Juan Wolf was once one of the most feared criminals in the world, and is noted to be the only known giant of his size, but was eventually caught by the World Government and sentenced to life in Impel Down, Level 6, where he was effectively erased from history, appearing as a huge giant in a cell near Ace's. Only a few people such as Emporio Ivankov knew who he was.

When Blackbeard and his crew came to Impel Down however, he was broken out of his prison cell by them along with Catarina Devon and Basco Shot. He and his fellow prisoners then joined Blackbeard's crew and went to Marineford.

Marineford Arc
He was seen alongside the Blackbeard Pirates and fellow criminals, all of whom have been recruited into the crew, and are now at Marineford to watch Whitebeard die.

Trivia

 * His surname San Juan may be a reference to San Juan Bautista, Puerto Rico's original name. Also, it could be a reference to the town of old San Juan in Puerto Rico, since it was a coastal stronghold filled with many ramparts to defend the island from pirates and rogue sailors, which may explain why his size is equal to one of Marineford's main buildings. The "Wolf" part of his name can also be an reference to the real life nickname of pirates being "Sea Wolves". And there was also a large battleship called the "San Juan Nepomuceno" that participated in the Battle of Trafalgar, which also can be an allusion to his nickname. Regardless, the origins of his name has not been revealed by Oda.
 * According to Vice-Admiral Strawberry, because of his size it is unmistakably San Juan Wolf as there is only one giant that huge.


 * He is the only Blackbeard Pirate not to attack Whitebeard.
