Toxicity

Izuku's Quirk

Quirk: Noxious Breathe

Instead of carbon dioxide that is exhaled, a thick toxic gas that attacks the surrounding air and any other living thing around, but the gas doesn't hold its form for more than a few minutes if the gas isn't constantly being fueled by the host. If the gas is released in a small dose to something living, it may render the person unconscious or struggle with respiratory problems. The effects of the gas can be amplified by other chemicals that are infused into the gas, for instance smoking a cigarette can cause interesting results due to it amplifying the toxins in the cigarette and sending it out into the air around the host. The host has a thick casing around their lung in order for the toxins not to cause internal damage to other organs in the body, and any added toxins have no effect (smoking won't cause any problems to his body for example). Due to the inability to 'turn off' his quirk, he manufactured with the help of the league a mask that could prevent the toxins seeping through, however, the toxins erode the material of the mask so the mask must be replaced every once in a while.

Now, some vague (sorta) insight into how Izuku originally activated his quirk is when he was fleeing from classmates (he got away) but he stumbled into an alley and initially started having a panic attack. Also, this tricked his body into thinking he was in a grave danger that was more life-threatening than being beaten by classmates (although they vaguely responsible too). However, due to Izuku already being the anxious kid he is, was triggered into another panic attack when he heard his classmates whispering about him, thus his body started to release the cloud of toxins, and due to the fact he was trying to calm down himself, he hadn't realised that he had basically gassed the entire class (apart from Kacchan who was sick or ditching or something). Also, the reason why Izuku felt like he was drowning to begin with when his quirk first manifested, was due to the lining that was forming on his lungs and the adaptation to changing the makeup of carbon into something much poisonous.

Hello My Lovely Readers~!

I just realised I forgot to add in the description of Izuku's quirk in the earlier chapters and thought I'd just devote this page to it. Also, if you have any questions about his quirk, I will gladly answer any of them. I may also change/alter this description or add to it.
