@Pokeysteve: He's pretty badass actually (takes place before the events in the movie). Now I'm not entirely sure if he takes round one (although Lady Shiva easily dismantled Killer Croc without being touched), but round two is a curbstomp for Ozy.
How did Shiva beat Croc?Think that matters for this fight.
@Pistolwhip1: Sauron wins. Maybe not quite in "stomp" fashion but somewhere near there. Having actually read the Hellsing manga I can say that Alucard is overrated. Before absorbing Schrodinger, Anderson is a worthy opponent for him. If he releases his souls to generate an army then he himself is reduced in power to something close to that of a regular human.
Even after absorbing Schrodinger I think Alucard wouldn't stand much of a chance. Schrodinger's powers are loosely defined but are generally summed up as the ability to control his state of being by thinking about it. If he thinks he's unharmed, he is. However, it's never really discussed what would happen if you fully disabled someone possessing that power's cognitive abilities.
When was Anderson ever a worthy opponent for him? And no he is not reduced to a power of a regular human, he was hurt and dismembered when he released his army and still had the same effect of healing, like he isn't phased by the injuries at all.
