Some one here please explain to me about Den O's final form.
 

Ok so what is the deal with Den O's "supposed" final form? I'm seeing couple of scenes where he is as Super Climax form and most or others as Liner Form. Even the battrider war game promotes Super Climax Form as his final form, and Decade Complete even has the Climax Form card on suit instead of the liner form card.

I'm not able to find a straight answer on google or atricles and the Kamen Rider wikia isn't much of a help either.

Was Toei just goofing off with Den O?

Well, Liner Form is Den-O's true final form, not using any Imagin, but Ryutaro's own strength.
Climax Form is Den-O's final form when combining all the Imagin.

Yeah, Liner is Den-O's true final form. It's Ryotaro Den-O achieving his final state, with the Imagin as "coaches." It symbolizes him basically becoming capable for himself

However, Super Climax is the five Imagin mixed into one. Since Liner doesn't include them as personalities and the Imagin are more popular, Liner looses out in recognition because the clowns have a bigger fan club.

Liner Form lost a lot of its purpose after Takeru Satoh left. It's kind of hard to use Liner Form when Ryotaro is a kid, and even harder when he's just entirely absent altogether.

Liner Form is the final form for the series. Like others said it represents Ryoutarou's growth as a character. However his most powerful form is Cho/Super Climax Form so that's used as his final form in all future "All Rider Final Form groupshot" appearances.

And then you suddenly have Momotaros controlling Ryoutarou at the Wizard Finale with him transforming straight into a Momotaros controlled Liner Form.
I wonder if Toei simply forgot about the Super Climax Form or considers Den-O to be it's own series vs Chou Den-O.
