2-10 TRITON
×3 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.
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.
St. Pigge's Alien variant — 60,000 HP, 250 AP area attack at 170 range with 100% Wave Attack. Common peon across CotC. Wave-Immune frontline keeps the line stable; Anti-Alien clears her.
Kid Tappa debuts as boss — 40,000 HP with a 15,000-HP Barrier but only ~50 damage per hit. Once the Barrier breaks, Kid Tappa becomes a free "stepping stone" you can stack Long-Distance damage behind — his attacks are too weak to push your line. Bazifenix breaks the Barrier; then Major Leaguer Cat and Crimson Mina print damage from outside Tappa's range.
Kid Tappa is the new boss — 40k HP + 15k Barrier, 50 damage. r/battlecats's framing: 'the Kid Tappa stepping-stone' — once his Barrier breaks, his ~50 damage makes him the safest place to charge meter for Crimson Mina, Polevaulter Cat, or Jellycat. Hyppoh + Shibalien Elite + Elizabeth the LVIth round out a manageable peon wave. Lineup: any Anti-Alien Barrier Breaker (Crazed Bahamut, Bazibon) → Mohawk frontline → optional meter-charging Ubers (Crimson Mina especially benefits) → Awakened Bahamut for finishing. Common failure: skipping the Wave-Immune frontline for Elizabeth — her wave hits multiple ranks at once and crashes lineups that haven't planned for it.
BAZIFENIX S 100% Barrier Breaker cracks Kid Tappa's 15k Barrier so the stepping-stone stage can begin 
MAJOR LEAGUER CAT A Long Distance 425~550 + Anti-Alien Resistant — perfect Kid Tappa stepping-stone backliner once the Barrier breaks 
CRIMSON MINA B Crimson Mina — Long Distance 300~600 area attacker; stack 2-3 behind the safe Tappa wall 
AWAKENED BAHAMUT CAT S Speed 60 Special rusher — finishes Kid Tappa's 40k HP after the Barrier comes down
