Wolver is a Human with Devil Beast Syndrome. He was caught by Lan Asukas group and chained up in a warehouse. when Jun Fudo was locked in with him, his urges made him bust outta his chains and go full daemon. he rips up Jun's body and clothes with blood spillage but Jun goes Urotsukidoji on him and punches down his throat, and tears off his right arm, causing a spray of blue blood (he's brittish?! no wonder he's so evil! just watch a mel Gibson movie!). So he seems dead and is taken away by the clean up crew but he revives (apparently regrowing his arm) and eats people. he fuses with some people or something and grows into a big a55 power rangers monster. he crushes Jun with his bare hands and destroys da warehouse, but then Jun goes to her Giga Form and they fight. And then... He died... AHHHHHHHHHHHHH!!
