2-21 ALDEBARAN
∞ 
×5 
×2 
×3 
×2 Faster, stronger Shibalien with 35% Warp chance back 750 range. Slowable/freezable like other Aliens. Bahamut can one-shot in its first appearance.
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.
Common Red peon — 2,500 HP, 150 AP area attack at 170 range. Spawns in groups. Any Anti-Red Area Attacker clears them.
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).
Some stages use Shy Boy as a speedrun trigger — killing him fast prevents a swarm.
Ribbo's 65k Barrier + 100% Warp at 400~550 range. Snipe with waves (Major Leaguer Cat).
Row 1 restriction continues; Ribbo (65k Barrier, 100% Warp at 400-550 range) replaces Pigge as the headline backline threat. Shy Boy adds dual-trait Red/Floating disruption. r/battlecats's note: 'Aldebaran 2 is where the Mystery Mask conversation starts — your treasure progress matters more here than in Ch.1.' Lineup (Row 1 only): Anti-Alien Barrier Breaker (Bazibon or Crazed Bahamut) → Mohawk + Manic Mohawk frontline → Warp-Immune Anti-Alien Uber (Lumina or Pixies-line) → Sir Seal / Star Peng cleanup with A. Bahamut. Common failure: bringing standard meatshield rotation without Survive cats. Ribbo's warp + Shy Boy's KB on Red trait combo will strip your line in 8-10 seconds.
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 Ribbo 65k 
AWAKENED BAHAMUT CAT S Speed 60 rusher — closes blind-spot snipers (Ribbo) before the chain
