My vote is for Spectre. Since he is essentially an agent of The Presence I don’t think Dr Smurf could actually manage to defeat him. Plus has Manhattan really got a huge counter for mystic powers?
I think Spectre has got this.
The Specter, God’s vengeance right? I mean c’mon…
Spectre all the way
The Spectre. Dr. Manhattan con scatter matter on a quantum atomic level, but Spectre can exist without matter. He is metaphysical, truly.
I would think that if Dr M had motivation to defeat the spectre, his foreknowledge of events in time and ability to see different outcomes would give him some advantages. I’m not clear on how one would harm or destroy the other.
Dr.Manhattan’s cool and all, but Spectre’s got the whole cosmic power of god able to manipulate reality itself kind of power going on, and I really don’t think that’s to be stepped lightly on.
