This enemy has very long attack range with the ability to freeze all Cat Units for two seconds. However, it deals very little damage. It acts as the enemy base for the stage, and the enemy itself is Metal.
This animated enemy base really only poses a threat in A Colossal New Year!, in which the freeze it poses can cause the Cow Doges in later stages to easily push through your meatshields and get to your attackers by the time they are no longer frozen. To prevent this, cats that are immune to freeze help a lot, especially if they are attackers. In the other stages Angry Sun appears in, it doesn't pose a threat in the slightest other then wasting your time if you didn't bring a critical hitter.
