Oh, I see. Those are interesting indeed.

Ah, cool. But I may have forgotten to mention that you get a pre-Knight Mega as well, unless you'd rather it stay Ultimate for longer than others.
Oh, and I might have it sorta center around missions, involving collecting data and eventually discovering the locations of Legendary Weapons, artifacts, or other aspects from/used by the Royal Knight form. So for you Rin, you could have Grademon or the next stage find the Dramon Slayer or something.

And I was thinking of using Raptordramon as my Champion, but I guess I could use Greymon X. That's what I usually use for that line anyway.
