Well it was mentioned some time before even GF that the roimudes rebelled against the scientists.

True but I think his question was about the Global Freeze and the Roidmudes' return afterward.

Edit: Nevermind I just reread the question he was talking about the Roidmudes' return before they initated the Global Freeze. my bad :o

So in Blade:Missing Ace, Kenzaki is able to seal the Joker. But in the show proper, he becomes a joker to stall the battle fight. Was it possible to seal the joker in the main show universe, or was Kenzaki's solution chocked up to self-sacrifice for his friend?

Self-sacrifice for his friend. Thought he deserved a chance to live life as he chose.

Not sure if it has been asked before or I might have asked it before and have forgotten but what were the problems with wearing the Kiva suit for Seiji Takaiwa?

Basically, it's a branching timeline. If Kenzaki sealed the Joker, Missing Ace happens. If Kenzaki becomes a Joker, then the series ending happens.

All the chains and armoring of the base Kiva suit (and the Arms Monster Forms) was too heavy for him and almost killed him with its weight. That's why they overused Emperor Form so much.

The weight was seriously that bad, I am not sure how bad it was but how was it possible of killing him or was weight the only factor?

I think weight distribution and combat action contributed too.

Notice how the chest and right shin contain most of the weight.

It does makes sense but damn I can't imagine what it was like in that suit if it bad enough be bad to to have problems for Mr Kamen rider.

Still a cool looking suit despite the weight problems.

Were there any other suits that Mr Kamen Rider had problems with besides Kiva?
