LeeMarvin80 reminded me of this guy. Not sure whether they're both supposed to be the same character or not, Brazil didn't really do the v2 thing, but they have the same name and similar filecards, so together they shall be.
Pantano
A Forca Naja, elite troop of the Cobras, needed a man for an important mission in the swamps. Found Pantano, a man born and raised in the Swamp! His best friends in childhood, were two alligators that sustains the neighborhood. One day a crocodile threatened Pantano with its rows of teeth. Pantano had no doubts. Transformed the poor crocodile in a pair of shoes. Since then his favorite hobby and hunt animals and people! With a superhuman ability to cope with mud, mud and sand, Pantano is always ready to pounce in Command!
Pantano
The largest of Pantano and commit attacks in flooded land and swampy, full of sewage and pollution. He arrives with his immaculate white clothes and come out laughing, totally dirty. Dirty himself, body and soul, because he is capable of the most "dirt" to achieve your goals!
He always has been. A former butcher, he loved his dirty apron. Blood, fat, viscera. . . The more dirty the better. The Cobras quickly realized that someone with these qualities would make a great fighter. . .
The backstories are fairly different, though not necessarily contradictory. I love the second one. It just gives him tons of character. I love the idea of him having a closet full of white clothes that he gets just filthy every time. I imagine he saves the dirty clothes too, but never wears them again. The first one is a bit less interesting, kind of Croc Master-y, but I dunno, just not as appealing as the second.
