Mister Fantastic vs Clayface

Random encounter.
No prep.
Bloodlust is off.

im pretty sure mr.fantastic would kick his ass...

Clayface.

Mr F wont need prep he could probably put Clayface down with his pocket calculator...

Well, he better be keeping something up his sleeve, because he isn't going to take Clayface down with physical force. While Clayface can suffocate him.
