Abel is far stronger than Alucard.
Fans of Alucard gets a hard-on so bad they equals DBz's.
What people don't know is that ALucard has been killed multiple times in the manga. Every time Alucard loses his head, he's actually dying. The only reason he doesn't stay dead completely is due to his soul count.
Think of it like an rpg. Where as Alucard soul count is his life point. Every time he dies, he loses a life point, or a soul. Once he dies enough times, he's gone.
Alucard is barely a bullet buster, his speed is only bullet time. He durability is shit. The only Alucard that can give Abel a fight is EOS Alucard.
Pre EOS, Abel makes Alucard his *****. Abel actually feeds on blood, what happened once ALucard runs out of blood? He becomes mummify, and don't say he can't become mummify because of his soul. The beginning of Hellsing proved other wise.
EOS Alucard chances of beating Abel goes up by 1. Alucard himself claimed, he he forgets himself he'll seek to exist. Guess what, Abel can make that happen.
Please, don't bring the whole Alucard is omnipresent bullshit. Why? Because id you're an Omnipresent being, you cannot force yourself to stop exiting since you exist in all time line. That's a paradox. Why? Because the Cat Alucard absorb to gain said powers forgot himself, that's why Alucard was able to win. He barely won, he had to sacrificed all of the other souls to beat the Cat personality from wining.
Also, don't bring the red herring of ALucard claiming only a human can beat him crap. It's like saying if Alucard goes against Darkseid, he'll win since Darkseid is not human.
Abel took on a being that survived being send crashing from space to the Earth. Create and control lighting.
Yeah, either way you cut this, Able wins.
