3-48 THE BIG BANG
×4 
×2 
×5 Final boss of CotC Ch.3 (Traitless). 1M HP, 800-range Multi-Hit ending in 66k strike. 100% Wave (Lv.12) AND 100% Warp back 1500 range on first hit. Mystery Mask required to keep him at 100% (otherwise 1,100%). Awakened Bahamut and Maglev Cat exploit the warp resetting their backswing.
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.
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).
Super Cosmic Cyclone variant — 44k HP, 666 damage at 5-frame attack interval (extreme DPS). 100% Warp FORWARD by 150 range. Very short 50 range; crowd-control with Seafarer Cat / Corrupted Psychocat / Iron Wall Cannon.
Beefy Gory variant with Area Attack and a 6,000-damage Barrier. Once the Barrier breaks he's vulnerable to crowd control (Seafarer Cat, Surge units).
CotC Ch.3 final boss. Final Boss Giga-God (Traitless, 1M HP, 800 range, Multi-Hit ending in 66k strike). 100% Wave (Lv.12) + 100% Warp back 1500 range on first hit. Awakened Bahamut and Maglev Cat exploit the warp resetting their backswing.
The endgame trial. Final Boss Giga-God has only 1M HP (less than Ch.2's Cat God!) but his Lvl 12 wave attack warps everything on the first hit and nukes on the third. The community fix: bring an Awakened Bahamut with the Explosion talent — his ~200k-damage knockbacks chain Giga-God's knockback animation, essentially locking the boss until a peon walks into Bahamut's range and breaks the loop. Required gear: Bahamut at level 30+ with Explosion talent, all Mystery Masks (43/45/47 superior), at least one anti-Floating Uber. The real killers here are Mesocosmocyclones — they push hard, stack with your Bahamut's range, and ruin your timing if you let them accumulate. Recommended lineup: Crazed Bahamut + A. Bahamut + Manic Lion meatshields + Ganglion/Twinstars for chip + a Doctor Cat to slow the wave. Considered the stage that unlocks 'real' Cosmos endgame; r/battlecats: 'if you cleared this you can stop playing the story and just go grind XP cans.'
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 GreGory 6k + Kid Tappa 15k 
AWAKENED BAHAMUT CAT S Speed 60 multi-hit Special rusher — front-loads burst on Alien peon waves
