Iida: definitely he's got the drive, he's pretty smart when he puts his mind to it and he also has a competitive spirit. I think Iida just may need a bit more of a spark of passion to put him close to the top with Midoriya, Bakugou, and Todoroki. Not to mention his power is super useful in its speed, he could be the first to the scene of a crime in an instant, and he's definitely got some potential and I can't wait to see what he does in the future as what he did in the cavalry thing was pretty insane.
Tokoyami: The raven guy with the shadow powers, he's just versatile and I was impressed by him when he teamed up with Midoriya. He's really good, and seems to be very aware of the situations around him. I'm really interested in learning more about him, and I can't wait to his abilities when it turns night time, as the Day and Night effect of his power is very interesting (almost makes him the batman of this world with shadow powers, lol).
Yaoyoruzu: I see her being really useful to people like Hero No. 13, not necessarily a powerhouse but the power to create anything that isn't living could be extremely useful to the world. She could plug up dams, build shelters, do some disaster relief. She's not necessarily a fighter, but she's creative and she's not bad at combat anyway her quirk just takes some time, so hand to hand combat could be tough.
I'll probably post others that come to mind later
