He's ok, you can't push to 18def so you really are getting just a 30pt perplexer with a 50/50 sidekick save. Most of the sidekicks are support pieces anyway so having them on their last click is still fine. A free nullifier for your Mr Fantastic is also a nice little bonus. He's not a bad piece but i dont think he's great either.

Too powerful and the sculpt is so big that I can't use it with the old scale

His trait for Mr. Fantastic is actually +5pts. Not free but still pretty good

I like the idea of putting this guy with a bunch of sidekicks on a team with SWB007b Thanos. This guy saves the kids on their last click just to be KO'd by Thanos to advance his trait. And of course the team would be named the Children of Thanos.

He should have a click where he is so annoying that he gets free Incapacitate with a 4 square range in every direction.

This represents everybody laughing at his jokes or being so perplexed that they can't figure out what to do next.

This keeps the figure in line with the 1970s cartoon!.
