Episode Yellow doesn't count. That's Chou Den-O, not Den-O.

But it's still in continuity with Den-O and involves the same cast of characters.

Ok , I'll give you that. That one slipped my mind. I had Kiva & Decade in mind when i said that.

i gotta ask, in saraba deno, they changed the denliner and the inside, which is fine although saddening :(, but in all the other movies after they go back to regular denliner, but keep the new inside. y?!

It uses characters from Den-O, but Den-O isn't a top billed character (It's Chou Den-O), thus not making it his crossover.

Conversely,
Think of it like Double Returns: Accel.
It's a Double movie, but it's not Double's movie.

also, ive herd chou deno means super super deno, does that mean kuuga super henshins

Multiple Den-Liners.

No, Chou Den-O is a different character, Ryotarou's grandson, Kotarou, with his own imagine and base form (Strike form).

but that doesnt explain y it has the old denliners outside but the new denliners in side

but hes only in three of the 5....

It can be explained away as simple renovation to "They had the old sets around after they Saraba (Farewell) Den-O movie, so they decided to continue using them."

What do you mean?

just kinda makes me sad how well never get an honest to god deno movie ever again :( :cry

kotaro only in 3
