Diends' powers are being blown waaaaay out of proportion, he cannot summon an army but he does have access to one in trios. That being said I'd probably have to vote for him based on the powers that he ACTUALLY has and has displayed. He would be able to steal the Hyper Zecter. I think we can all recognize that he'd probably take it before Caucasus would notice. All he needs to do is take it to another world and leave it there. Caucasus' biggest advantage is now shut down and he is primed for Agito to beat him.

Diend goes invisible and chills to the end. I think at this point the other 2 would be on even footing in the battle. But I believe Agito would come out on top, though injured. Then we get some Riotrooper cannonfodder while Agito is weakened. He takes them out with some degree of trouble after being nearly drained against Caucasus. Diend goes Complete Form for the finish.

I love Agito to death but I see this as the only logical conclusion to this battle.

cuacases still has clock up...... hed still win...

The smell of bovine fecal matter is strong with this one. Seriously, all DiEnd can do is summon three knock offs at a time ans take pot shots. That stands no chance against the likes of Agito and Caucasus(who I voted for).

Well, he could always summon Caucasus! He's done it before, in Cho Kamen Rider Den-O & Decade Neo Generations The Movie: The Onigashima Warship.

Yes, but that's only a copy and not as skilled or powerful as the original.

True, but it would be enough to stun Caucasus long enough for DiEnd to slip away.

Current poll:
Agito: 4
Caucasus: 4
DiEnd: 10

FYI I voted Caucasus. I also don't get Diend's deal. Maybe it's assuming his presence stupidifies Agito and Caucasus to the point they could get beaten by a summoned Plat Form...

People seem to be vastly overestimating DiEnd's abilities. I'll accept that neither Agito nor Caucasus has the built-in defense against Invisible like, say, Kuuga or OOO would, but the idea that DiEnd's copycat summons are on par with the real Riders is, in my opinion, wrong. It especially doesn't help that, knowing DiEnd, he'd probably waste time by summoning Riotroopers, which never, ever works.

While they may not be as strong as the real riders, they don't necessarily need to be. They just need to be strong enough to throw the opponent off guard while Diend goes and does his own thing. The Riotroopers are useless, but summoning characters like Sasword or Momotaros have fared pretty well for him in the past.
