Even if you could show me feats of alucard's magic being able to transcend to not physically interact with some one to do harm, it doesn't matter.
If it must physically cause harm, Tetsuo siphons it and just deflects it from touching him. If it exists some how out of the current plane to cause damage, that doesn't matter, because I already showed that Tetsuo can combat off other Telekinetic attacks. Those are also not technically in the realm of physics and explanation besides what has been shown over the years.
I'm sorry but, Magic follows under very strict rules to every universe it originates from it. It's not free or construct. Please inform yourself about that before continuing. I don't need to debunk you. You need to provide proof of how it works in order to even make his magic plausible. The burden of proof is on you.
Tetsuo has shown he can deflect and shield from pure energy from a solar powered laser, let alone he can neutralize and deflect attacks that are unseen and on a mental level of existence from other psionics. Alucard's magic is no exception. Neither are his cheap parlor tricks going to even effect Tetsuo.
I provided proof and canon quotes how Tetsuo deals and can destroy Alucard. Alucard so far only has ONE thing going for him, regeneration, and I already debunked that. He needs souls to keep coming back, how many times does Tetsuo just need to sit back and evaporate his body into nothing before Alucard can't repeat the process.
Read what I type thoroughly, because I already disproved and debunked practically everything you said. This isn't a battle of magic vs science, because magic is science fiction. As are Tetsuo's ability, all science fiction. I just am merely showing and proving to you through science, physics, anatomy, and so forth to make it realistic.
And show canon quotes and proof he sucks blood to get souls? because, I don't even know how that makes sense. Usually people just steal a soul separate of needing to draw blood in anime. Perhaps he has to kill them first by sucking their blood and needing it to sustain with oxygen (which is to help his physical body stay alive) then after the victim has died of blood loss, he can capture the soul and use that to power his (energy/magic). The Souls don't keep his physical self alive and moving.
Any way. Alucard is just a highly advanced vampire. And you have no proof he doesn't need oxygen, so the fact he can still be taken to space to die stands. You think Tetsuo's powers are science? They're made up as well. No one can really teleport or etc irl. It's science fiction. so is magic. And if you're saying that Alucard's magic is unexplainable, then good, you can't use what can't be explained. Try to find some canon description. Until then, debunked and defeated. And it's proof that Alucard's attacks have to some how touch their opponent, and I said, that isn't going to happen to Tetsuo.
Tetsuo can affect Alucard. Alucard can't touch Tetsuo. Alucard can regenerate but with limits. He will eventually not be able too. Tetsuo will become the victor.
Tetsuo is OP like I said and should just be banned or not brought up in discussions. If you feel frustrated at how stupid and unlimited he is, that is just the case, that is how he is. Even I think it's retarded how powerful of a character he is, but Tetsuo is Tetsuo.
