as cool as it would be to see somebody like goku blasting haruhi into nothing, it really wouldnt go that way.
Typically in these thread there is always one big assumption made, that main target and all of the challengers are in the same universe. Unfortunately with Haruhi you can't really do that. Its her thing. All that exists in her universe plays into her grand subconcious scheme and everything else is just not there. The only possible challengers are those that have hax powers that traverse across plains of existence. So while somebody like goku can instant transmission around his own universe, there is nothing to prove that he can go between universes or dimensions besides death which everybody can seem to do.
So for the sake of the thread, I submit for your approval, one Yukari who I don't have a picture of on my laptop.
