That laser they used on Worldbreaker Hulk probably could have done the job as long as they got his hole body in it and he hadn't been attacked by any other, lesser lasers for a while. It'd take something extremely broken like that though.
>>78035993Locking him in the cell would work for a while, probably. He would quickly become comfortable and self sustaining in the cell, but probably wouldn't develop teleportation because no risk. However, he has situational benefit adaptaiton as well (they gave him an IQ test, he was smarter by the end of it). He'd start punching the wall eventually, and sooner or later he'd doomsday it, getting thicker and tougher hands and more strength to keep hitting the wall harder. It'd take him a while, but he'd get out.
