Eclipse would be the counterpart of both personalities and appearances of Moon and Sun mixed together, but lately, he hasn't been acting himself. He's been violent, aggressive, forceful, and hostile. So much so that Sun had to forcefully put him away so that he didn't have as much power to change at will anymore. He's become like a virus, corrupted by an unknown force, and causing both of them harm. Lately, he has become more reckless and has been finding ways to break both of them down.
