well raiden (remember this s from mgs4 not 2 lol) is friggen insane he got crushed by a state sized battle ship like fortress and came back he is immortal in the same sence as dante, if dante is obliterated he cant come back true he doesnt need his organs but if theres nothing left dante loses raiden is a great sword fighter and raiden also has inhuman strength given the quicksilver would give dante an advantage but it would still be a great match giving the battle to any of them anyone else have a theory?
