×5 Dolphina variant — 40,000 HP and 15,000 Barrier, but only 50 damage. Speed 50 makes him a fast meat wall. Once the Barrier breaks his low DPS makes him a useful stepping stone for Crimson Mina / Polevaulter Cat / Jellycat.
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.
Kang Roo's Alien variant — 24,000 HP, 2,800 AP area attack at 199 range with 100% Knockback. Disruptive. Knockback-Immune frontline + Anti-Alien backliners.
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).
Kid Tappa: 40k HP + 15k Barrier, low damage. Can be used as a stepping stone for Crimson Mina / Polevaulter / Jellycat once the Barrier breaks.
Kid Tappa replaces UltraBaaBaa as the front-line miniboss; Scissoroo adds 2,800-AP Knockback pressure; Star Peng still anchors the backline. r/battlecats's read: 'Mercury Ch.3 punishes lineups that lean on Crit Cats — Kid Tappa is a wall, not a Metal.' Mag scaling means even peons hit for 5k+; your meatshield rotation matters more than your DPS pick. Lineup: Manic Mohawk + Crazed Lion + Cyborg Cat (Knockback-Immune) → Warp-Immune Anti-Alien Ubers (Lumina, Bora/Pixies, Mighty Reza) → A. Bahamut for Kid Tappa burst once Barrier breaks. Common failure: stacking too many slow-rate Ubers under MAX 20. You need volume of attacks to outpace Star Peng warp + Scissoroo knockback — slow Ubers spend the stage swinging at empty air.
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 Kid Tappa 15k 
AWAKENED BAHAMUT CAT S Speed 60 multi-hit Special rusher — front-loads burst on Alien peon waves
