and now for number 3

DeLeo uses a Kama (is that correct?). he was burned almost bald at a concert thrown by a character in the next group to come by the game's special guest star Boss

Maramo uses a sharpened shovel, and is a tribute to a certain animal celebrity :P

Gris-Gris uses a modified fish hook, and wields his weapon with his tail, as, you can see, he's missing a limb (damn feral gators, non?) the colors are off, as I only worked from memory.
