Imperator Sael (ゴマサーマン, Gomasāman) is an enemy that appears in Chapter 4 and Stories of Legend.
This enemy has decent health and moderate attack damage. It might slow the movement of your cats, so beware. This enemy also has area attack. To defeat it, use high-health cats like Crazed Tank to stall it, and use high-damage cats like Bahamut to take it out.
This enemy is much stronger than the normal Sir Seal you find in some other levels. But, it has time between attacks and 2 knockbacks, unlike his red counterpart. To kill it, spam meatshields while also spawning in strong hitters like Valkyrie and Bahamut Cat to take it out.
Imperator Sael is a blueish-green (cyan) alien, and has 2 antennae growing out of his/her head, unlike its other variants.
A walrus warlord who came from space to fight Earth's Red Seals. No hands, but still tries for handshakes to be polite. Won't see me lyin' about this classy gent.
