Ironhide is tough on the outside but frail on the inside (ref. his tech specs). Blackout can beat him fairly easy by slamming him repeatedly into a hard surface. I's innards would be scrambled and he'd be helpless. After a while, his brain chip would snap and he'd die.
B could fly the deactivated I to a deep part of the ocean and drop him in, to be crushed by the water pressure. [Oh, I do think such fun thoughts!
