REVENGE OF N-1
Revenge of N-1 is the 2nd stage of King Wahwah's Revenge. Previous stage: N-1 Grand Prix. Next stage: Wrath of the Dogelord.
An exact copy of N-1 Grand Prix, but the Super Rare-only restriction ironically makes it easier than the original.
- Useful Super Rares are far more accessible than the Normal/Uber/Legend pool the original demands.
- Their disposability plus generally weak peons means the stage can be brute-forced.
- Express Cat and Swimmer Cat abuse King Wahwah's knockback count — rush the start with Maglev.
Zoge and Zang Roo revive after dying — without a Zombie Killer they keep coming back. Bring one to end the loop.
ZOMBIE CAT B Zombie Killer — stops the revive so it stays dead. Also fits “Clear the crowd.” 
TEACHER BEARCAT A Zombie Killer — stops the revive so it stays dead. Also fits “Counter Traitless.” 
PILEDRIVER CAT A Zombie Killer — stops the revive so it stays dead. Also fits “Clear the crowd.” 
MIGHTY REKON KORPS S Zombie Killer — stops the revive so it stays dead. Also fits “Burst the boss down.” 
MR. B Zombie Killer — stops the revive so it stays dead. 
BAKERY CAT A Zombie Killer — stops the revive so it stays dead. King Wahwah is Traitless. Anti-Traitless units take less damage and deal more.
TEACHER BEARCAT A Insane Damage vs Traitless (Normal form). Also fits “Stop the revives.” 
BRAINWASHED AXE CAT A Strong against Traitless and Curses Traitless enemies. 
D'ARKTANYAN S Strong Against Traitless on a Long-Distance area attack — answers the many Traitless bosses. Also fits “Clear the crowd.” 
BOWLER CAT A The Slow lands on Traitless enemies — great for stalling the many Traitless bosses across Empire of Cats and Into the Future. 
BRAINWASHED BIRD CAT A Massive Damage (and True Slow) vs Traitless. King Wahwah reaches 600 range. Units that out-range it can chip safely without taking hits.
King Wahwah has a deep HP pool (1,000,000+ even before stage magnification). Heavy single-target burst shortens the fight.
BAHAMUT CAT S Huge multi-hit burst — a story-unlock powerhouse that deletes tanky enemies. MIGHTY REKON KORPS S Among the highest single-hit Area damage available. Also fits “Stop the revives.” 
GAIA THE CREATOR S Long-Distance multi-hit with Insane Damage — a generalist wall-cracker. 
CRAZED MONEKO A Big crit burst against tanky/Metal targets. 
IZ THE DANCER S Big Multi-Hit Massive-Damage bursts. Also fits “Clear the crowd.” 9 enemy types stack up here. Area attackers hit the whole push at once instead of one unit at a time.
ZOMBIE CAT B True Form hits groups with Area attack. Also fits “Stop the revives.” 
SALON CAT S Hits whole crowds, and is Weaken-immune so it keeps firing through Weaken stages. 
NERD CAT A Evolved/True hit groups over a Long Distance band. Also fits “Out-range King Wahwah.” MIGHTY REKON KORPS S Long-range (Omni Strike in True) Area clears groups front and back. Also fits “Stop the revives.” 
VALKYRIE CAT A Hits the whole group while it freezes them. 
The castle you destroy to clear the stage.
