i can see this going in two way:
either monoma will be smart and remember how deku would get his bones broken every time he would use his quirk (at the tournament arc)
<OR>
or, monoma being monoma, tries to copy one for all and gets his limbs "flying off and blown to bits" (ch.2 pg~13) or more reasonably, not being able to handle one for all he would scream in anguish and erasure would neutralize him to keep him safe and this entire class A vs class B exercise would stop with more attention towards deku and his quirk
the examiner's faces are just too much XD rotflmao
