[Aoi Kurenai]

Wasn't Emperor described as Kiva's "true" form? If that's the case, it would make sense that he used it fairly often. I actually thought the drawback to that form would be Wataru somehow being unable to control the form. Rewatching the episode in which it premieres shows Wataru as pretty vicious during the battle, especially considering how much we had come to know the Fangire he took out in that episode.

Favorite base suit: This one is a tie between Fourze, Kiva, Wizard, and Hibiki. I enjoy Hibiki because it's a beautiful suit and so different from anything before or after. It works so well for its theme. Kiva's also up here because I sort of see it as the opposite of Hibiki. While Hibiki is the weird experimental suit that has a very lowkey design going on, Kiva seems like an experimental suit with all the shine of a regular Kamen Rider suit.

I also love Fourze because I'm a huge fan of Ishinomori's designs and I think it's as close as we've ever gotten to a Kamen Rider suit with all of the Ishinomori proportions rendered in real life.

The Wizard suit I also find to be beautiful in motion. It's regal, black on red is a great choice, and the flowing coat adds to the action scenes. This is a suit that lends itself so well to the sort of action they had going on in that show. It's just a shame it wasn't in a better show.

Favorite power-up suit: Kuuga Ultimate. It's one of the few power ups that I think portrays the increase in strength and devastating effects it can have on its user.

Least favorite base suit: Probably OOO. It's not as bad as it could have been (Super TaToBa is what I thought the suits would look like when early rumors came out about it being segmented into three parts) but it definitely never appealed to me. The power ups strike me as more interesting in that show.

Least favorite power-up suit: Going to go ahead and say Decade Complete. They had a cool idea with the colors - pink, black, and silver are a great combo, but pink was literally relegated to a couple of lines and then, of course, you've got that line of cards.
