Comic book used as a marketing vehicle for Ali.
Superman and Ali have to fight for the fate of the world, with Supes made normal and given almost no training. He goes down in the second round.
Rating loses reliably to Ali, by KO 1/3 of the time in 4rd bouts - included a pre-prime that is more prone to be KO'd
As a bonus, loses reliably to Bear's Batman rating, almost only ever winning by KO, which sounds right
Specifically for this version of Superman, not what I would use for a superhero fantasy universe.
Clark "Superman" Kent
HW - OR: 7 (pre-prime 5)
