Franky

Franky is strong-willed and free-spirited, with an often blatant disregard for rules. He does whatever he wants whenever he wants, though he usually wants little more than to build powerful ships or protect those he cares about and at times can appear very eccentric compared to most of the crew. Franky often sings a song or plays a guitar to express his feelings while accompanied by him denying he's crying while he is obviously crying. Depending on the situation and the people he is dealing with Franky can be quite an altruist, as he is quick to defend other people and take action if his friends are harmed, he also holds the belief that no matter what a person is like, they should never be prejudiced or exterminated simply because of who they are. This often causes him to befriend and defend the wrongfully feared and persecuted. Because of his unbiased and protective attitude, he is quick in making friends and allies with the most unlikely of individuals, such as street thugs and pirates. He is seen as a 'big brother' figure, and is admired by many for his efforts to protect them, such as Nico Robin and the Franky Family. Monkey D. Luffy and Franky share some personality traits, with the exception of fighting needlessly, and both grew to respect each other during the events of the Enies Lobby arc despite the disputes the two had in the past.
He tends to say the word 'Super', sometimes spelled "SUPA!", while doing his signature pose. Another of his habits is to refer to the 'current week' for exclamation as in "Of course I'm strong, and I've been especially strong this week." or "I've been like this all week."
He has a running gag of being unintentionally linked to "perverted" things due to a combination of his clothes, strange personality and the situations he gets himself into. His lack of fashion sense seems to stem from the fact that his creativity leans towards crafts and mechanics, which would explain his style of clothing which usually consists of nothing more than his trademark speedo, a large golden chain necklace around his neck and a shirt concealing his rather bulky upper body build.
Franky's personality can alter somewhat, depending on the beverage in his system.
