Eleven

Dragonhead, Seven and Eleven were Yakuza assassins targeting Patch/Wolverine. They took the performance drug "Thunderbolt" which granted them super-strength and suppressed their fear and pain. However they were aware that the drug was lethal. Their plan was simple. Seven and Eleven impaled themselves on the claws of their target, using their weight to trap them under them. Meanwhile Dragonhead was attempting to decapitate the target. The plan did not work.
