×5 Boxing kangaroo — 4,000 HP, 250 AP single-attack at 160 range with 100% Multi-Hit (3 hits per attack). Tankier than typical Traitless peons. Anti-Traitless or pure DPS overload.
Tiny but spawns constantly — distraction unit.
Faster, stronger Shibalien with 35% Warp chance back 750 range. Slowable/freezable like other Aliens. Bahamut can one-shot in its first appearance.
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.
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).
UltraBaaBaa's 266k Barrier and Star Peng's 100% Warp on the same stage — a two-phase fight. Bazifenix solves both at once (100% Barrier Breaker + Warp Immune). Loincloth Cat is the Special-tier Barrier Breaker backup when your Uber slot is taken. The MAX 20 cap is generous; bring a tight Anti-Alien core rather than padding the lineup.
MAX 20 stays, UltraBaaBaa replaces Hyppoh as the front-line wall, Star Peng still warps. The 266k UltraBaaBaa Barrier turns this into a two-phase fight: crack the wall, then deal with the Pengs already warping your DPS off-screen. r/battlecats's quoted line: 'don't go in here without Loincloth Cat or Bazibon if you want consistency.' Lineup: Anti-Alien Barrier Breaker (Bazibon, Loincloth, talented Crazed Bahamut) → Warp-Immune Anti-Alien Ubers (Lumina if you have her, otherwise Pixies + Mighty Reza) → Mohawk + Manic Mohawk frontline. Common failure: using Bahamut alone for boss DPS — Star Peng will warp him during his backswing and the run dies.
BAZIFENIX S Solves both threats at once — 100% Barrier Breaker for UltraBaaBaa 266k + Warp Immune against Star Peng 
LOINCLOTH CAT B Special-tier Barrier Breaker backup (30% chance) — stack behind Bazifenix to ensure the 266k wall comes down 
LUMINALIA S Anti-Alien LR with Warp Immunity — holds the front through the Barrier-break window 
AWAKENED BAHAMUT CAT S Speed 60 Special rusher — finishes the low-HP UltraBaaBaa once the Barrier cracks
