I believe this fight will be more interesting due to elemental powers.
Percy Jackson was dropped into Marvel Universe (616) to contest with Magneto
- No BFR
- No prep
- Moral off
- Collateral damage acceptable
- All feat counts as long as it's canon
- No outside help (Avengers and X-Men were eating burger), but everything in the island can be used for any purposes if valid
- To the death or KO
Manhattan Island, Magneto is on top of the Avengers Tower, Percy is nearby the Statue of Liberty (environmental advantage matters)
Again, just like any other of my movie vs comic thread, I don't mind if you use movie or novel version for Percy (but I prefers novel due to feats).
