- Scans of Mephisto saying he could kill Silver Surfer with a thought
- Torturing Surfer
- Transforming into that evil - looking form and vaporizing tons of souls in Hell
Yea Mephisto is pretty powerful. In Secret Wars when Dr. Doom stole the Beyonders power he was gonna raid Mephistos realm to get his mothers soul back or something. He wouldn't dare try it without it.
