I believe it all fell on Megaman X's special weapons and his armor upgrades he got from Dr. Light that needed some workmanship and design like the SNES days. Alia should have had the Arrow Shot from Mega Man 8!

I have no complaints toward Zero, Axl, or Layer. Pallette needed more upgrades from Mega Man 7 and 8 though.

I also wish The Turbo Accelerator would return!
