This enemy has decent health and moderate attack damage. It might slow the movement of your cats, so beware. it will be a threat the first time you meet it and an even bigger one the second as the second time you meet it, it has an extremely high buff; 560%. 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, and is half as fast. 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.
