I know I know, I posted this a while back. But that was really unorganized. And no I didn't take a hell lotta time to figure these out. I watch a lot of things to notice these. Anyways, for those who read/watch One Piece, you'll fully understand these puns.

Gold Roger (Or Gol D. Roger):His name is obviously a pun on two things possessed by pirates: gold and the Jolly Roger (The skull flags pirates have on their ships). Nothing else can be said.

Alvida:She's the fat pirate woman from the first episode who later appears much more skinnier and sexier. She was actually a real pirate long time ago, and both Alvidas wore a similar hat.Picture Comparisons

JangoHe's obviously modeled after Michael Jackson. He even moonwalks and has a fascination of attacking boys.Comparison pictures

Klahadore aka Kuro:Kuro was modeled after Kevin the Cannibal from Sin City. They both have claws and gleaming glasses. And both have hunger for kill and stalks in the night.Comparison Pictures

Lt. FullbodyThis naval officer was modeled after Mr. Orange from Reservoir Dogs.Comparison Pictures

Dracule MihawkThe strongest swordsman who nearly killed Roronoa Zoro. I really don't know the lookalike's name, but the resemblance is uncannyComparison Pictures

Mr. 9 and Miss WednesdayThis is a big one. This couple was modeled after Austin Powers characters. Mr. 9 tends to stick out his pinky thumb often, just like Dr. Evil. Both also have costumes VERY similar to Austin and his partner. Whenever departing, they say "Bye Bye Baby".Comparisons

More later, but there is a character based off Sonic the Hedgehog.
