I agree with cwb8109...
I'd like to see what happens with Kayleena/Enid (you did use both names in there, after all).
Omegas' and Xeros' skills, and if the gloves are any clue, Kary-08s' as well.
Omega got a shit death though... resurrected by XV, just to die again after taking a direct Longinus Knife blast from Kary... sucks, in a movie scene kinda way... but, you done great with Xionic Madness.

Hell, start to finish, I think you nailed a good 60 minutes minimum total movie length. Could be wrong, as I always lose track of time watching the Xionic Madness series. A few years in development, and it just keeps on being awesome.
If I could apply any of my would-be sayings to this series...
Nothing but Aces, Xionico.
Like a hand of Poker with Jokers wild, you got the best hand out there, nothing but Aces.
