Forms, or Riders?

[Kamen Rider Critias]

What are you saying!? IXA and Kiva battled it out with their bikes!!! IXA HAS a bike...

Oh ya i forgot about that. But still it's only one scene (i guess you could count it has riding that crane thing)

Actually for the whole forms or riders thing... it really depends on the show because it works differently with different shows.

No not just one scene... The other scene which happened first was when IXA sends Kiva flying off a building. The bik clash happens as a re-match of that...

True, though Amazon has an upgrade in his human form. I mean, at a certain point he wears a jacket instead of runnin around all naked
And a white dress that's awesome on him.

you can also think of his improved speaking skills as an upgrade too.
