But then he wouldn't get the personal thrill and rush of stealing stuff himself.

The summoned riders also don't seem very... smart? I definitely wouldn't trust em with a heist!

Speaking of Diend's summoned Riders, has there ever been any kind of official clarification on what exactly those are? As in, are they supposed to be the actual Riders themselves he's summoning, or are they just some kind of copy? Their behavior kind of implied the latter, since they don't ever really express any personality beyond filling whatever function Diend needed them for, but I don't think I've ever seen any explanation of the exact mechanics of how that works.

What's even weirder is that sometimes they do exhibit some personality -- signature poses for instance, or Psyga's maniacal laughing. But obviously very few of them would go along with what Diend wants especially when it comes to more heroic ones like Birth and Todoroki, so... ????

My theory is that they’re projections, to go with the camera motif the show has. Though I know someone suggested that he summons them and brainwashes them to serve him.

... oh, yeah, and then there was the time he summoned Black who was just straight up Kotaro Minami

But it's technically an alternate Kotaro Minami. Man Decade is confusing. Did you know that the Kenzaki Kazuma from the final episode of Decade isn't the original one.? Toei has retcon him to be an alternate version as well.

Diend not making any sense? This too is Decade's fault.

Well I guess the best answer then is to just never try to make any kind of coherent sense out of Decade. :lol

Simple, they're projections except for when they're not :P
