1-1 EARTH
1-1 Earth is the 1st stage of Cosmos Ch.1 — Beyond the Exosphere. Next stage: 1-2 Mars.
Shibalien Elite is Alien. Anti-Alien units take less damage and deal more.
GROSS CAT A Its True Form is Strong Against Alien, giving budget anti-Alien value. Also fits “Out-range Shibalien Elite.” 
LI'L GROSS CAT B True Form has a 30% Knockback vs Alien. Also fits “Out-range Shibalien Elite.” 
BAKERY CAT A Curses Alien enemies. Also fits “Out-range Shibalien Elite.” 
LITTLE LEAGUER CAT S Resistant vs Alien and Long Distance — a budget anti-Alien backliner. 
CATMAN S Deals Massive Damage to Alien in every form. Also fits “Out-range Shibalien Elite.” Shibalien Elite reaches 120 range. Units that out-range it can chip safely without taking hits.
GROSS CAT A Range 350 — fires from beyond its 120. Also fits “Counter Alien.” LI'L GROSS CAT B Range 300 — fires from beyond its 120. Also fits “Counter Alien.” 
PSYCHOCAT A Range 365 — fires from beyond its 120. Also fits “Counter Alien.” 
BACKHOE CAT A Range 350 — fires from beyond its 120. 
GUNDUROS S Range 500 — fires from beyond its 120. Also fits “Counter Alien.” First CotC stage. 4 Dagshunds spawn early, then a single Shibalien Elite as the boss at ~20s. Bring your Moon (ItF Ch.1) lineup minus Anti-Floating cats. Awakened Bahamut Cat one-shots Shibalien Elite.
The tutorial stage every CotC player remembers — 4 Dagshunds and a single Shibalien Elite boss. r/battlecats consensus: 'if your ItF Moon (1-48) lineup beat this, you're cleared for the chapter.' The Shibalien Elite swap from Floating to Alien trips up Anti-Floating-heavy lineups; that's the whole onboarding lesson. Standard loadout: Mohawk + Manic Mohawk frontline → Awakened Bahamut for the Shibalien Elite one-shot → 2-3 Anti-Alien Ubers (Bazibastra, Lumina, Bahamut Cat). Common failure: showing up with the ItF Norway lineup (heavy Anti-Floating) and watching Shibalien Elite shrug everything. Bring Anti-Alien Treasures from ItF Ch.1-3 before attempting.
