Now I cannot stop imaging the Class A students as some of the shepards from Awakening, like with Ida as Fredrick (serious no no sense types, who have some eccentric traits that they are not fully aware of), Invisible girl as Kellam (obvious reasons), Mineta as Viviron (except Viviron is more classy, but give Mineta time), Hanta as Stahl (since they are about average in their groups, and that they are both rather mobile), Deku as either Donnel (growth rates and starting as the absolute weakest thing in the beginning) or Robin (tactical main character), and I think Momo might make a better Maribelle rather than a Cherche (because I think of her more as a support hero and because both come from a wealthy background which plays a role into their characters) and Todoroki might also work as Gerome (for the many obvious reasons).

Anyone got any better ideas?

You are absolutely right about Tokoyami, but I think Kirishima is more like Gregor ( since they can get along with just about anyone, can tank hits well and

I just realized one of my other suggestions was completely wrong, clearly Yuga would be Viviron, although I am also uncertain about choosing Maribelle for Momo.

minor note, had to edit this comment because I made a mistake twice with the spoiler tag warning
