Assume this is Hitsugaya at his strongest and he's a human on Earth but still equipped with his sword and powers.
Hitsugaya has the Hogyoku embedded in his chest in this fight.
Iceman has a 5 gallon bottle of water strapped onto his back that doesn't really weigh him down.
He is fighting Iceman in the Sahara desert, though there is a small oasis of water 1 mile nearby and both of them are aware of it.
Who slaughters who and who gets roflstomped?
