Unexpected Marvel characters who could Destroy the World if mind controlled

These characters, while regarded as powerful (and sometimes not so much), just don't quite seem to get quite as much powerhouse cred as they deserve.  If they should come under mind control, these characters could well be used to easily destroy continents.  I imagine a scenario where B-list Marvel villain The Controller gradually builds up an empire of enslaved superheroes with his control discs and actually manages to pose a significant threat to the world at large.  NOTE: Some of these characters are or may be dead.  But hey, this is comics, so people can either be brought back OR the story can just be set at a specific point in the past when the required character was still among the living.
Also... let's throw just a few villains into the mix so we can make them do some things they'd much rather not do.
