×2 Worm/serpent Alien — long range area attacker with 100% Weaken on hit. Standard Anti-Alien backliners trade hits cleanly; Weaken-Immune cats (Pixies, Cyborg Cat) play through it.
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.
Fast and tanky for a peon — knocks back meatshields.
Kang Roo's Alien variant — 24,000 HP, 2,800 AP area attack at 199 range with 100% Knockback. Disruptive. Knockback-Immune frontline + Anti-Alien backliners.
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.
Kid Tappa: 40k HP + 15k Barrier, low damage. Can be used as a stepping stone for Crimson Mina / Polevaulter / Jellycat once the Barrier breaks.
