The Guppy beast has shown itself to be extremely powerful as it can suck in almost unlimited amounts of magic energy. Has shown the ability to destroy all currently active spells within an area, permanently destroy active spell beasts((possibly destroying Alucards zombie soldiers, I'm not sure)), and suck up incoming attacks.
However I think the main point of this thread would be the fact while neither of them can die, only Yakumo has the ability to seal away his opponent.
Then this fight is already descided by that factor of him being able to seal Alucard away.If you want to go by that logic of seals then yes Alucard loses.........But if you go by the other logic of certain seals work for certain foes then no Alucard doesn't lose... (I.E demon warding seals from china don't effect the demons from japan and vice versa ((to make it simpiler pretty much seals (paper and magic wise) made from a different part of the world used on demons (or other evils of the world) don't effect them (unless it was made just to effect that one kind of demon or evil))) I know this sounds like it is mumbo jumbo but there is evadence from many different animes as well as religious thinkings to this "fact".
Another thing people have to consider is........ will he use the seal right off the handle? if his head or limp or other body part is blow off does this ruin his concentration to use the seal? how long does it take to use this seal effectively? And is alucard at his full power with no restions on him at all (I.E his glasses and gloves and cromwell act) And is alucard playing hard ball and going all out? (He has done this a few times and didn't even joke around like in the anime and manga) And If alucard ate him would that count as winning?
