2-34 THANXBYE
∞ 
×2 Hippoe variant — 7000 HP, 200 dmg Area Attack at 222 range. Tough first encounter in ItF Norway but a glorified Hippoe once you have Valkyrie / Bahamut and ItF Treasures.
Faster, stronger Shibalien with 35% Warp chance back 750 range. Slowable/freezable like other Aliens. Bahamut can one-shot in its first appearance.
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).
Teacher Bear's Alien variant — 30,000 HP, 1,000 AP area attack at 350 range with 100% Strengthen. Boss of Egg Nebula / Eskimo Nebula / Venus Ch.3 / Thanxbye. Anti-Alien backliners + tank-heavy frontline; cap him before Strengthen stacks.
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.
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 Ribbo 65k 
AWAKENED BAHAMUT CAT S Speed 60 rusher — closes blind-spot snipers (Ribbo) before the chain
