He'll probally lose. But I don't care. Ore Sanjou!

Den-O, always Den-O. Except if its against OOO.... So almost always Den-O

I still argue that Kuuga is the strongest Rider. Aside from riding the time train to stop Godai from getting the belt, what can he do to him. None of his forms are strong enough to even take a Rising form, are they? Let alone Amazing or Ultimate.

Kuuga would spend more time wiping Den-O's face off his boots then it would take to defeat him.

Damn it

I tried Den.

For future battles, whenever Den-O is involved, can you include the disclaimer that Den-O can't just ride the Den-Liner into the past and prevent his opponent from becoming a Rider? Because that seems to pop up in all of his fights...

For serious.

i Don't Care if Kuuga is the revival of Kamen Rider TV Shows. he can get week if he not protecting the planet no more so during this time of the battle is taken places he prob be need to relearn all his forms from scratch,where as Den ould just need the imagin of said mastered of the skill and he got the battle so there no why Kuuga could win if my theory is the case no need to time jump on a train Den can win hand Down i know he can i Belive in Den-o and the power of Momo.

These battles take place with all Riders at their prime. This isn't Kuuga returning to the streets like a Watchman.
