The Grand Priest is calm and polite, however, mysterious and enigmatic. He has an easygoing personality and is not stern. He never shows any annoyance and is flexible and humble despite his high status. He also seems to have somewhat of a sinister personality as he was shown to be smiling after the erasure of Universe 9 and 10, giving off a sadistic side. He also seems to have a lot of knowledge about the universes. He’s short and thin with white slicked back hair and pale blue skin.
