My first thought for a quirk was something along these lines: Quirk Name: Guardian Angel Quirk Type: Transformer Quirk Basics: A sentient angelic being exists as a permanent companion to , existing for the most part as a visible halo of light above 's head. This angel can speak directly into 's mind to warn him of approaching dangers and the like while in this form. In fights, can take on some semblance of the angel, granting them physical changes and a variety of angelic powers, while at the same time giving up part of their agency to the entity itself. Quirk Strengths: [list][*] 's ability to pick and choose how much of the angelic form to take on allows them to tailor their powers specifically to each engagement to avoid tiring themselves out by taking on powers they don't need. The primary powers he can call forth are: Angel's Wings (a pair of feathered wings able to carry up to 300kg total in flight without serious strain), Angelic Senses (Can detect lies, increased reflexes, improved sight, smell, and taste), Angelic Physique (increases physical stamina, pain endurance, and physical strength by a great deal), Angelic Arsenal (Can call a flaming sword, bow, and/or whip out of thin air. Can only be touched without harm by ) [*] can call forth limited miracles, such as healing others, casting out individuals who are possessing others, or even in the direst need raising people from the dead [*] Even when completely exhausted, the angel will never need to sleep, and always retains some level of its divine senses, making it extremely difficult to sneak up on or surprise , given the constantly watching guardian looking out for them [/list] Quirk Weaknesses: [list][*] Total Possession can last for only up to three minutes before the angel is completely exhausted, and must return to its halo form to rest until the next sunrise (God's First Light being what gives it power). If the angel is not able to absorb the rays of the dawn, it will remain exhausted until it is next able to see the sun (time is no longer relevant at that point). Depending on how much of the angel's power is drawing on, the partial possession can last up to 2 hours for only one power, with each additional power drastically reducing the amount of time before the angel exhausts itself. [*] The angel's miracles can never directly affect . He can never directly heal himself, only others around him. Additionally, miracles will cause the angel to become exhausted for a proportional amount of time, with major miracles potentially taking days to weeks for the angel to become strong enough to manifest itself again. [*] The more of the angel takes on, the less control he has over himself, on a slowly escalating scale which ends when he fully takes on a Total Possession, where their roles reverse, and is simply an adviser rather than fully in control. This may lead to the angel doing things that would not wish to do, but the angel will always work toward what it believes to be his interests, and the Total Possession can be stopped at any time, at the cost of exhausting both parties significantly. The angel can choose to take full control voluntarily, but if it does so it can only be as a Total Possession, and the angel can only keep it maintained for 30s before it becomes exhausted. [/list] Quirk Techniques: [list][*] Total Angelic Possession: The full power of the angel is unleashed, taking on its full form as a searingly bright figure of light with flaming weapons and a terrible visage. Any and all powers are available for use for the full duration of this ability, though no matter how hard the fight is, this form can only last for three minutes, after which the angel is completely spent and retreats to its halo, with no longer able to call on any of its power. [*] Angelic Visage: Light spears out from every surface of , making them appear larger than life. Foes who look at 's face during this time are struck with a deep terror which sears them to their very soul. Friends and bystanders who look upon 's face feel calmed and rejuvenated simply by looking at him, though there is no physical benefit or harm that comes to any individual who looks (other than retinal damage for anyone stupid enough to stare at for too long [*] Heaven's Fury: Drawing their hands together, can draw on the fury of the heavens, manifesting itself as either a cone of white-hot flames or a piercing beam of white light capable of piercing through most objects [/list] I'm not sure on what power level you expect for these characters, so this might be a little much? Please let me know your thoughts and I can tweak and modify this as needed!
