Stu was the guy who fought Wolverine in the cage match.
Stu was willing to fight an undefeated champion in the cage match. The anouncer told him not to kick him in the balls. Stu questioned him saying I thought everything goes. The announcer replied that anything goes but he will take it personal. After Stu kicked him in the balls, Logan got up and took him out.
After the fight when nearly everyone was gone, Stu came up and wanted his money. Stu then got a knife and went to stab him from behind. Rogue, who was sitting nearby, screamed look out and Wolverine got out of the way and put his claws to his neck.
