White Phoenix vs Jim Jaspers vs Mr Mxyzptlk

All at full strength,no morals,neutral universe.

World's Funniest Mr Mxyzptlk and Mad Jim Jasper both possible stalemate.

White Phoenix dies horribly.

Mxy

The question is what do you look at, the potential the character has, or the clear on panel feat he has demonstrated.

Based on potential MJJ can take Phoenix , based on clear on panel feat and not a dream about a potential future where he destroyed the omniverse, he has limited feats.

Mxy has the best feats here,world funniest however is non-canon, he still has the best feat here, so a reasonable thing would be to go with Mxy.

So its:

1. Mxy

2. Phoenix

3. MJJ

been wondering the same thing myself, what to look at, potential or on panel feats. Mxy has the best on panel feats, so id say he wins.
