whoa whoa whoa SLOW DOWN. You keep throwing these vague, hard-to-follow terms at me, it's going to be the series-arc of Den-O all over again and no thanks. Like, there's all this jargon that you haven't explained.

HOW big is "giant"?

WHICH of the Alien movies is he from?

WHERE is Earth?

See, I can't be expected to follow premises like these. It's all so convoluted! Ultra Nonsense!

Almost half as big as a first generation XBox controller.

The one where they take over an office building in New York and Tony Randall does the Alien Queen's voice.

Just outside Akron, Ohio.

And that's why we're here to give you accurate and helpful answers to your questions.

And that's why I'm here: to be the person that needs all of these things explained to them. Will you all explain things to me until the very end?

I'm not gonna fight you on that, Kai ain't worth that time :D But, fair I guess, he's by far one of Kobayashi's better villains by the simple fact that he's not really annoying, like a certain computer virus that acts more like a bratty child that didn't get his sweats...

So, yeah, his weakness doesn't detract like it usually does.

My problem with Kai that I do not know what is he? Why he so powerful? Why Imajin follow him? And also he is not that threatening.

So, two answers to Kai's deal.

The first answer is couched in the world of the show. His mystery is what makes him so terrifying, as does his contradictory demeanor. He's Ryotaro inverted: externally charismatic and internally blank; chewing up memories because they're just fuel for him; bored by adventure; using the Imagin as cannon fodder. He's scary because he's the horrifying alternative to being a Singularity Point. He comes from nowhere, he can be anywhere, and he answers to no one. He's a metaphor for all the things we want to forget, the parts of ourselves we'd rather burn up to reach a blank slate. Ryotaro is about the power of memory; Kai is the seductiveness of forgetting.

The second answer is that Kai is the show's self-critique of endgame villains, and how you could do one on a show that's all about internal journeys. Kai doesn't give a shit about explaining himself, because the show doesn't give a shit about explaining Kai. The point of Kai is to be a somewhat arbitrary menace to defeat, but nothing that should pull focus from the character development. Kai needs to be not that important, or the show loses what everyone's watching it for.

If Kai seems underwhelming, I'd argue that a) that's what makes him hard to predict as a villain, and b) what makes him such a unique take on that character type. He's a world-destroying villain who is bored of the World-Destroying Villain trope. I really love that approach.

Climax Deka should in near beginning of Kiva. The Final Countdown after Kiva. The battleship movie during Decade. New Denso after Decade.

Alternatively, Climax Deka could come never, save yourself a wasted hour or so?

Your thoughts on Kai being great because they don't actually go into any detail about him... You truly have already become Fish and their love of fog banks.

It's, like, the one part of my brain that's like Let This Perfect Mystery Stay Mysterious And Perfect. It's a dude who shrugs when the heroes ask him if he's the endgame villain! I can't believe I have to defend him!!!

I guess, to walk back the Fish comparison, I additionally like that the show never made a big deal about Kai's history or connection to the series-arc. He's a metaphor, and an obstacle, and that's it. Maybe it's lazy writing (I could listen to that argument without agreeing with it), but there is absolutely zero narrative tension expended on Kai's secrecy, and I love that. It's the opposite of the Sakurai stuff, where the show couldn't shut up about it past a certain point. Kai exists, and that's sort of it.
