Gory Black and Shadow Boxer K will be spawned at mild intervals for the rest of the battle.
Most anti-Black cats are Uber Rares, which makes this level harder if you do not have those Ubers. Otherwise, fight this level as if it was Attack on W-Cyclone. However, the Nyandam does not really do anything, unlike THE SLOTH in Attack on W-Cyclone.
The Black Cyclone is also very weak in terms of attack power compared to most other Cyclones.
Strategy 1 (No Uber)
Lineup: Macho Cat, Wall Cat, a third optional meatshield, Cameraman Cat, Cat Eastwood, Paris Cat, Ring Girl Cat, Bahamut Cat, Valkyrie Cat and any other cat able to slow/freeze Black or Floating you have, such as Shaman Cat or Delinquent. If you do not have Ring Girl and/or Cameraman in true form, it is not a problem, as they can also be replaced by other attackers.
Start with meatshields and the cats with slow/freeze against black, as to create a small stack before attacking the base. When that is about to happen, start spamming everything and watch as the boss struggles to advance and eventually dies. If the horde of black enemies pushes too much, focus on attackers until they die, then spam everything again.
