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.) Freeze is also useful, so units like Divine Coppermine completely destroy this stage.
Strategy 1 (Raiden, White Rabbit)
Row 1: Ururun Wolf, Executioner, Evil Cat, White Rabbit, Prisoner Cat
Row 2: Li'l Whale cat (Li'l Island is better, but not required), Island Cat, Lufalan Pasalan, Raiden, Crazed Bahamut
Catcombos: Masquerade & Under Arrest
Powerups: Cat CPU
Note: Lufalan and Bahamut can be replaced with a long ranged, anti floating/red of your choice.
Strategy: Spawn Li'l Whale and Island cat until your worker is max and your wallet is full. At this point, all you have to do is turn on the CPU and wait. Raiden in combination with the White Rabbit and Ururun Wolf will keep the cyclone from getting past your stream of Whale/Islands. It may get dicey, but none of your heavy hitters should end up dying.
