Wrath of R-Cyclone is the first stage in Crimson Vengeance. It grants 1 million XP when first completed.
Cat Deploy Cost: Only 1200¢ or more
It is an exact copy of Attack on R-Cyclone. However, there is now a restriction in place, leaving the player unable to use meatshields and many cats that would otherwise break the stage, such as iCat, Sanzo Cat and Cameraman Cat.
However, that doesn't mean that there aren't any units who can make this stage as easy pie.
Uber Rares are the units you should mainly focus on. Megidora can knockback and slow Floating enemies, Raiden can 100% knockback Red enemies (True Form is optional), The White Rabbit can 100% slow Red enemies, and the list goes on. (Peach Angels, Balalan Pasalan, Kamukura, etc.)
