I tell you the stupidest character even would have to be Eye Scream-Powers: Eye-Scream had the superhuman mutant ability to turn into any flavor of ice cream he wishes. He could "melt" himself down with the assistance of his (I kid you not) unstable molecule refrigeration unit. This allowed him to ooze through barriers such as bars or underneath locked doors.
In theory, he may have been able to harden his body with his refrigeration unit, giving him increased durability. His ice cream body may have been resistant to many conventional forms of attack, as they would pass through him. Perhaps his ice cream body could be sculpted into various shapes, as well (okay, maybe I’m giving this guy way too much credit; it’s what I call pity power stunts).
