I honestly don't think I can stay in a roleplay where one character has powers like that. Antimagic dog and emotion-controlled reality warping (especially when their personality starts with 'happy and confident') in a magical girl RP? Every other character, unless people start taking 'life and death' or 'eternity and the instantaneous' to their logical extremes, is basically a sideshow. And I have no interest in being a bit character where the outcome is entirely dependent upon a single person's mood.
