Your reactions to awesome things make no sense to me :(

Oh yeah. I forgot about the Diend part.
I don't remember if they explain why he shows up beyond "He's a Decade character and it's 1/10 Decade's movie."

Blade Raider's dislike of anything beautiful is spreading

But I don't get it, isn't Diend a good guy? Why was he in that time? Why did he attack New Den-O? Why did G3 attack New Den-O? Why'd they dissapear after they were posessed? (that was awesome BTW) Why didn't Decade help in the final battle? Why didn't Decade tell Diend to fuck off and stop making life hard for them?

Also, even though I saw it coming a mile away, the kid being Yuuto was kind of cool. But seriously, is Den-O just the series where every main character of consenting age gets reverted to a child? I hope this isn't the last we see of Yuuto's actor now. If you don't have Den-O why you gotta make Den-O movie, Toei?

I don't dislike the movie at all, it just slow before that final battle and Diend is a buttface. The gag with fooling the bad guys and Super Climax form were funny, and having the Imagine posess the other riders was awesome... though it'd be awesomer if they didn't just keep using their weapons since, well, what's the point?

And yet that's somehow better than liking Goseiger. :p

Diend shows up because Kaito is, at heart, a troll. His main reasons for doing things are 'I need to do this to steal something' and 'Imma mess with that guy's (usually Tsukasa's) head'.

In the case of this movie his motivation seems to be 'Tsukasa and team Den-O messed up my plans in Den-O world, so I'm gonna interfere whith them trying to fight this other bad guy.'

What an endearing character type.

It is for Tendou.

Tendou still does the right thing, though.

In the most Troll way he can think of :lol But he's never taken two crests, created a giant ass robot to destroy the world, just to teach Kagami some BS lesson that makes no sense to start with.
