×3 Doge variant — first Alien enemy you face. 900 HP, 150 dmg, low movement, hits for solid damage at melee range. Easily killed by Lion Cat / Crazed Sexy Legs / Bahamut.
Croco's Alien variant — fragile (3,000 HP, 900 AP, 130 range, no abilities) but appears in 42 CotC stages with magnifications scaling from 100% to 2,400%. At high mag his DPS climbs to 12k-25k. Crazed Sexy Legs / Macho Leg / Wheel Cat clear groups easily.
Fast attack rate for a peon.
Bore's Alien variant — 160,000 HP, 1,799 AP area attack at 125 range with 100% Knockback, fast 17f attack interval. Boss of Uranus + Urura + Andromeda. Knockback-Immune frontline (Bombercat, Crazed Cow with Talent) + Anti-Alien backliners.
Faster, stronger Shibalien with 35% Warp chance back 750 range. Slowable/freezable like other Aliens. Bahamut can one-shot in its first appearance.
Nimoy Bore boss — Long-Distance Anti-Metal sniper with Crit + range. The ROW 1 restriction means only your bottom row deploys; pick units that don't depend on rear-row backup. Major Leaguer Cat from row 1 outranges Nimoy Bore from behind your meatshield. Awakened Bahamut handles peon support.
MAJOR LEAGUER CAT A Long Distance 425~550 from row 1 outranges Nimoy Bore's sniping; the Anti-Alien Resistant cuts incoming damage in half 
BAZIFENIX S Anti-Alien Insane Damage from row 1 — wipes Nimoy Bore and the Shibalien Elite peons in the same pass 
AWAKENED BAHAMUT CAT S Speed 60 rusher closes Nimoy's blind spot before he can Crit your row-1 line 
MANIC ERASER CAT S Cheap fast row-1 meatshield — Bazifenix and Major Leaguer Cat need this wall
