Appule is loyal and obedient, obeying orders from both Zarbon and Lord Boxman with immediate effect. He seems somewhat competent and intelligent, taking on the role of Snively after his passing in the orbiting space pod called sky spy. Alongside his fellow soldiers, he views the heroes with little more than contempt, openly smirking as some of them were killed by Shigaraki and Monster Zero, and having some of them getting their quirks taken, harnessed, and roboticized. He can also be arrogant and somewhat cocky, as he was openly taunting the wounded Vegeta moments before his death.
