User blog comment:Mellowix/Theory: How Aizawa's Quirk Works./@comment-46594423-20200811173310

I like the thought. A few issues for you to work through

1) if it's truly small, biological levitation, and Aizawa hides it for the fear factor, then why wouldn't he cut his hair? It becomes obvious he's using his quirk when his hair goes up, and even more obvious his hair is levitating.

2) we see Aizawa get named Eraser Head by Present Mic while they're in school. So by the time they were choosing hero names (first year), he had already shifted his quirk focus, and gotten it working (if not mastered)?

3) less an issue, more an adjustment: its hard to imagine disjoining strands of DNA inside of every cell in the entire body. Instead, maybe think of how genes are expressed through the construction of proteins?  He could limit that process, maybe by making enzymes no longer contact the dna?  I'm thinking if there's an enzyme (call it Quirkase) that facilitates the expression of Quirk genes, he could just make all the Quirkase in the entire body float?

I'm not a biologist so maybe I missed something but you get the point.
