Zweilous' Outrage is actually strongest since Rivalry is pretty much unreliable and he's actually pretty cool under TR
Err, why shouldn't Rivalry Haxorus count? The fact that it is unreliable (which I agree with) doesn't make it weaker or less valid at all. And it's not like Hustle is a reliable ability either. Sorry, but the strongest (not best!) Outrage award goes to Haxy, whether you like it or not.Actually Zwellous's Outrage is the most powerful in the game even counting Zekrom and Rayquaza's Outrages, and not counting Rivalry Haxorus which is too unreliable [...]
Backing away from that, it's funny how Quagsire ignores even Durant's accuracy boost after a HC, so there's that (screwed some of them over in RU).
