Abyss Skullete

The Abyss Skullete is a post-Moon Lord enemy that is encountered during the Dawn of the Void before midnight. They are spawned with Abyss Skulls in groups of 2 (3 in Expert Mode and 4 in Awakened Mode), idly rotating around the Skull until it dies. Upon its death, the Abyss Skulletes seperate and charge at the player. They can also be damaged while rotating around the Abyss Skull, allowing them to be killed before they start attacking; however, they are invincible during this phase in Awakened Mode.
