[@SimpleWriter] Okay, I finished my Quirk so I decided to post a WIP sheet to work it out with you. I decided to combine the scream element with the physical enhancement idea, but made the scream a consequence of abusing his body by storing up too much sound for too long. This makes the collateral damage a suitably rare event, making its dangerous aspects justified, as it's basically a superpower meltdown. Is his Quirk acceptable as written?

[color=fff200]Quirk Description:[/color]  Alex's ears can project (currently) a variable-length invisible "sphere" around him, up to a radius of 20 meters. Any sound that enters is instantly absorbed into his ears and stored in his body. To anyone within this zone, it is completely, utterly, oppressively silent. Alex himself can't even talk when this bubble is active because his voice is instantly absorbed back into his ears. This makes him rather effective as a stealth asset.

But what does he do with all of those stored-up decibels? He uses them as fuel. The more sound Alex has absorbed--up to his body's "cap" of around 100 decibels (or about the volume of a jackhammer), the more his strength and speed improve, at a rate of about a 400 pounds bench-press and a 40 miles per hour sprint per 10 decibels absorbed, though as he trains his Quirk, his cap may increase. This leaves his present strength and speed capped at 4000 pounds and 400 miles per hour. However, his sound absorption isn't cumulative. If he stands on a busy city sidewalk for an hour and absorbs an hour of 90-decibel sound, his strength and speed are only at the level of 90 decibels.

Storing pent-up sound waves in your body is not without consequence, however. Prolonged storage of levels at or near his cap can cause Alex significant problems. At thirty minutes, he gets a sense of malaise, like a person who is coming down with an illness but whose symptoms haven't manifested yet. At forty-five minutes, he starts to feel significant stomach discomfort. At an hour , he starts to get a headache. At an hour and a half, the headache intensifies to migraine levels and he becomes seriously nauseous. At an hour and forty-five minutes, he becomes short of breath. And at two hours, his body begins explosively venting the sound through an involuntary scream that, depending on the amount of sound stored up, can cause massive collateral damage, especially if his cap has grown beyond 100 decibels.

The only way to avoid this is for him to vent out the sound on his own. The sound, when being vented, is basically a combination of every individual sound he's absorbed. Because of this, it generally sounds like unlistenable auditory sludge. Thankfully, he can do this slowly over a longer period of time to avoid collateral damage, like slowly letting the air out of a balloon instead of deflating it all at once. Of course, the quieter it is, the slower the drain, so there's always a trade-off between effectiveness and ambient noise level (especially in a stealth situation).

Side-effects of his Quirk include a complete immunity to loud sounds (to the point where he's never experienced "too loud" in his [i]entire life)[/i], and the ability to speak at and hear sounds of any frequency.
