Sorry W , but you got stuck fighting the wrong one!

Not even a contest. OOO is easily one of the strongest Riders in this whole thing (possibly even second most powerful) and he is unmatched in terms of versatility. I love W, but I don't see any way that this isn't a curbstomp.

OOO easily. Eiji has the tools and the know-how to use them. Double is crafty, but he's lacking in power, which OOO has in spades.

I don't even think he has to bust out TaJaDor or PutoTyra. Most of his other combos can take him out with little fuss.

But as I've said before, Double is crafty. He's not going to telegraph his attacks the way Fourze would. But overall, OOO is a powerhouse.

This is an easy win for OOO, sorry Shotaro and Philip. Eiji is easily one of the strongest riders ever.

OOO. Cause of OOO on here. That's about as deep as my pick gets :lol

ooo. even if w is smart and powerful ooo can just use gatakiriba and use every form at once

I don't know if Eiji was ever that strategic. I mean, most of the time he just used whatever people threw at him. But whatever.

So here are my predictions for the winners:
OOO V W: OOO
Amazon V Super-1: Amazon
Kuuga V Birth: Kuuga
S. Moon V Kiva: S. Moon, because he's the most badass Rider Villain ever.
Dark Kiva V Den-O: Dark Kiva
Skull V Decade: Decade, because he's a Mary Sue & no one can beat him.
Knight V Agito:
Eternal V Kabuto: Kabuto, because Clock-Up.

They're the second last riders who will ever fight each other :lol

Honestly them fighting would've made a much better crossover than what we got. :lol

But I have to hand this one to OOO.

:lol OOO would win in every sense of the word. W has nothing on him. If the W fanboys carry him to victory I will be very displeased. Stacking these 2 up its no contest a win for Eiji.
