×3 Spawns in groups of three. Area attackers clear them fast.
Tiny but spawns constantly — distraction unit.
Massive 266,000-damage Barrier (one of the largest in the game) protects very low HP. Anti-Alien Barrier Breakers (Bazibon line, Loincloth Cat) cut through cleanly.
Only takes 1 damage per hit. Critical-hit cats only.
Tankier Metal — same critical-only rule.
Metal variant of One Horn — 800 HP, 3,200 AP area attack at 80 range, attack interval 6f (extreme DPS). Only takes 1 damage per hit. Critical-hit cats only (Crazed Whale, Cyberpunk, iCat).
Master A. variant — 451 range area attacker with 20% Warp chance back 500 range. Outrange with backliners or rush past with Awakened Bahamut / Maglev Cat.
Croco's Alien variant — fragile (3,000 HP, 900 AP, 130 range, no abilities) but appears in 42 CotC stages with magnifications scaling from 100% to 2,400%. At high mag his DPS climbs to 12k-25k. Crazed Sexy Legs / Macho Leg / Wheel Cat clear groups easily.
UltraBaaBaa's 266,000-HP Barrier is the highest in the game. Anti-Alien Barrier Breakers (Bazibon line, Loincloth Cat) cut through.
Project A + UltraBaaBaa double-threat. They want different solutions: UltraBaaBaa needs Barrier Breaker; Project A needs Anti-Floating + range. Talented Crazed Bahamut covers both surprisingly well. r/battlecats consensus: dump everything front-loaded (Bahamut variants + Crit attackers for UltraBaaBaa's slow window) and accept that you'll burn one Cat Cannon. Mystery Mask treasure run for Ch.2 closes here — collect the superior before 2-48 or repeat the 30+ attempt mistake from Ch.1.
BAZIFENIX S Anti-Alien Uber primary — 100% Barrier Breaker + 100% Weaken vs Alien handles every Alien threat on the stage 
LUMINALIA S Anti-Alien LR tank — ~1.9M effective HP vs Alien + Warp Immunity, stalls anything the stage spawns 
LOINCLOTH CAT B 30% Barrier Breaker — Special-tier crack for UltraBaaBaa 266k 
AWAKENED BAHAMUT CAT S Speed 60 multi-hit Special rusher — front-loads burst on Alien peon waves
