In another world.

Demon God [Who the Hell are you? You slaughter all of my gods like they are nothing.]

Allen [I'm just here to have fun. Collasping Mass]

The entire planet get suck into a small black cube.

Allen [This really starts to bore me. There's no worthy opponent to fight against and I still can't teleport correctly except near the mountain side or my home.]

A serious looking guy came out with a jacket.

??? [So you're killing the Demons Gods. I don't like that. It is the balance of the universe to keep them so I will have to stop you or you're going to die.]

Allen [You really think you can beat me. You don't know who your opponent is king of gods. Or should I say EXX. That's a strange name you got there.]

EXX [Can't believe you actually know my name but that doesn't matter because you obviously choose to fight me.]

Allen [I don't think you understand my power. However, I can see your power very well.]

EXX [Then fight.]

Allen [You come to me.]

Allen creates a massive blackhole. EXX gets trap by the blackhole.

EXX [This won't trap me.]

EXX use his bare hands to destroy the black hole but gets blasted by Chaos beam. EXX cough up some of his energy but regain his balance.

EXX [Well that hurt. Now where is he.]

EXX activate all seeing god eye.

Allen [Boo.]

EXX [What the*Bam*]

EXX is sent flying light years away.

EXX (All seeing eye is not able to detect him.)

Allen shows right behind EXX.

Allen [Of course All seeing god eye is not able to detect me because I am able to by past it's vision.]

EXX try using an energy to cut Allen but Allen is too fast. Allen is not using his hands and is kicking EXX face.

EXX [How dare you!]

EXX fires his beam and Allen takes a direct hit it erases the space around them both.

EXX [How did you like that]

Allen is standing there like nothing is happen because Infinity and Zero negated the attack.

Allen [You finish yet.]

EXX [No more games.]

EXX release his restrictors and the two duke it out. With Allen having Infinity and Zero Allen is invincible that has connection with the world and does not have infinity energy. Even if they do Allen is older than the universe he's in at over a trillion years old. The one that is equal to him is the World God but will most likely lose.

EXX [Who are you? I haven't heard of anybody that is strong as you]

Allen [A World God slayer...killer from another world sent by the Creator.]

EXX [IIITTTTITITITIT can. It can die!!!]

Allen [Of course. Just because he's the highest chaotic being of this world doesn't mean he can't die.]

EXX [What are you going to do with me]

Allen [I just want you to be my servant.]

EXX [....Ok, fine.]

Allen went back to the guild and sees Lucy and wave to her.
