Fisher Tiger

Fisher Tiger, known as the Adventurer, is the original leader of the Sunny Pirates.

Personality
Tiger is said by Hancock to be a reckless person, and very brutal, seeing how he challenged Mariejois and burned the entire city down to free all fishmen slaves.

He also very much hated humans (mostly because humans slaved fishmen and treated them harshly), but did not discriminate when the some humans were slaved also, and freed everyone of them during his raid of the holy city.

Abilities
Tiger has a very strong will and power to climb the Red Line with his bare hands (which is 10,000 meters from the ocean surface). He also challenged the Tenryuubito and their guards to free fishmen slaves.

History
Several years ago before the current storyline, he climbed up the cliffs of the Red Line with his bare hands to Mariejois. He attacked the holy land to free the Fishmen slaves there from the Tenryuubito. While he hated humans, Tiger did not discriminate when it came to slaves. He freed slaves of all races there. Among these other slaves were Boa Hancock and her two sisters.

With the Fishmen slaves he freed, Tiger changed the shameful hoof mark branded on them (it signified slavery) into a symbol of sun. He also took them in. With them, he created the Sunny Pirates.

(It also should be noted that Tiger did not change the Hoof sign on humans)

At some point in time, Fisher Tiger somehow died and his command of the Sunny Pirates was given to Jinbei, who later became a Shichibukai, which then caused the Sunny Pirates to separate.
