Spider deku

Izuku midoryia or known as deku to his classmates, decided to take a trip to a lab giving tours near u.a.this lab specializes in quirks and they were trying to get quirks to be passed down they started experimenting with spiders they succeed but it only works on quirk less people because having the quirk gene blocks the ability and all most all the quirk less people being in there 80-90s they give up but one spider escapes before it can be shutdown.
