×3 
×5 
×2 Le'boin variant with 40,000-damage Barrier — one of the strongest in the game. Bahamut, Bazibon-line, or any 100% Barrier Breaker is the standard counter.
Spawns in groups of three. Area attackers clear them fast.
Croakley variant — Long Distance (400~550) backliner with 65,000 Barrier and a guaranteed 100% Warp back 250 range. Only 700 HP — once the Barrier breaks, waves or Major Leaguer Cat finish the job.
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.
Worm/serpent Alien — long range area attacker with 100% Weaken on hit. Standard Anti-Alien backliners trade hits cleanly; Weaken-Immune cats (Pixies, Cyborg Cat) play through it.
100% Warp chance back 500 range for 3.3s — extremely disruptive. Low range vulnerability. Counter with Area Attackers and Warp-Immune cats (Bora/Lumina line, Rover Cat Mk II).
Ribbo debuts as the boss. Ribbo's 65k Barrier + 100% Warp at 400~550 range. Snipe with waves (Major Leaguer Cat).
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, Ribbo 65k, Le'Solar 40k 
AWAKENED BAHAMUT CAT S Speed 60 rusher — closes blind-spot snipers (Ribbo) before the chain
