Izuku is empathetic and kind and has a strong drive to be a hero. Typically, he is viewed as a "nerd" stereotype and is rather smart. Having a habit of mumbling under his breath and stepping in where most wont, some people find him annoying. 

He is also an Omega with a spring rain scent, compared to others he will stand up to an Alpha if needed, but he's not a brat. Usually preferring to not get involved with dynamics and instead focus on school.
