Overlook
This Stage is very difficult without Ring Girl because the Gory Blacks And Dark Doges can break through your defenses easily especially when the boss comes out, the boss is very difficult and could last for a very long time if it weren't for one thing, Its a black enemy. Because of this it allows you to use abilities such as plane cat's knockback, Cat Eastwood's slow ect. this makes the stage bearable because plane cat's knockback makes it so the boss can barely advance and only having just over a million health makes this a reasonable stage. I would not recommend CPU for this because you need to be very aware of whats being sent out because a single Gory black could tear through your defenses and allow the boss to advance.
Strategies
Strategy 1(NO Uber)(sorta)
SO First of ide like to point out this page was empty the time i started writing this and im very middle game so please send help to this page
Line Up:Macho/Mohawk Cat, Wall/Eraser Cat, Third meatshield(Crazed macho really helps because his high speed can compensate for the Boss' DPS) Plane/Robo Cat(knockback), Paris/Macho Legs(Damage Dealer), Ring Girl Cat(High DMG vs Blacks can easily kill gory blacks), Dragon/King Dragon Cat,(stackable Heavy Hitter), Valkarie Cat(support dmg), Bahamut(core dmg dealer.) I dont know if Awakened Bahamut would be good here because of poor range but eh if you want to try it out. ( i actually did this with Mighty Lord Gao at level 19 but this strategy still words without him since all he was doing was an extra 15000 dmg and killing off peons therefore not 100% necessary but makes it much easier.)
