this being marvel and knowing that marvel NEVER shows namor any respect and that marvel almost always gives the home team the advantage..this being hercules' own title: herc will will. they have fought to a standstill before. in the water: namor would kill herc! in super-villain team-up, reed richards stated that namor no longer gets weaker the longer he stays out of the water. i guess the other marvel writers never got the memo.
