Izuku Midoriya

Bio: Ever since Izuku was young he's wanted to become a hero, idolizing All Might. But he never developed a quirk. After a doctor visit it was revealed he was one of the few people who wouldn't develop a quirk. Despite this he still wanted to become a hero and started studying other people, heroes, their quirks, and how they fought.
But due to his kind nature, belief and ambition, and lack of a quirk, he became a victim of bullying, specifically by Kacchan and his friends. This didn't change, even years into the future when he was graduating middle (?) school. But one fateful day he's attacked by a villain and saved by the hero that ignited his dream to be a hero, All Might. 
All Might recognizes his bravery, ambition, and potential to be a hero and decides to help Deku make his dream a reality.

Aspect: Alright so obviously everyone is thinking Hope as his aspect. And that is definitely a possibility and one of my theories. But I have another theory I want to check out as well.
Those bound to the aspect of Heart are very concerned with their favorite subject: themselves. It wouldn't be a stretch to call them 'self-obsessed', but not necessarily in a negative way. They simply want to understand the one thing we all are stuck with for our entire lives, i.e. our own minds. Forging an identity is extremely important to the Heart-bound, and every decision and action goes toward building a coherent narrative of their own story. That isn't to say Heart-bound don't care deeply for their friends and allies; they just have a tendency to assume that everyone is as concerned with identity as they are. They are excellent at putting on and taking off masks as the situation calls for them. At their best, they are competent, imaginative, and steady. At their worst they can be overbearing, inflexible, and cold.  
Those bound to the aspect of Hope are driven first and foremost by their convictions. They do right for right's sake, and are quick to come to the aid of anyone they deem to be experiencing injustice. That said, their views of the world can be quite black and white, so what they see as the "right" thing may not always be the universally accepted view. They put great value in the power of the imagination, the ability to dream up a better and more beautiful future. If anyone could dream a better world into existence, it would be one of the Hope-bound. They may sound like all sunshine and rainbows, but they aren't adverse to a little destruction, especially if they think they can replace it with something better and more just. At their best, Hope-bound are positive, caring, and warm. At their worst they can be narrow-minded and selfish.  
Alright so I think we can scratch out my theory of Heart. I only considered it because the story is about him carving his own path and learning how to use his quirk and be a hero.
But he definitely fits the Hope aspect better. He fits it so well that I don't think I need to say why or how he fits it honestly.

Class: Once again I think it's fairly obvious what his class is. He is very clearly an Heir.
Honestly almost every protagonist of a story ends up being an heir, which isn't surprising given the fact that the Heir is all about adaption of the self which is in a way what being a protagonist is about. 
"They aren't just open to changing themselves, they are also heavily inclined to influence change in others. This knack to affect others may not present itself directly, but something of their own or related to them could hold a similar effect."
We already know Deku is all about changing himself- he's willing to destroy himself to accomplish his dream and has done incredible things just to make it a reality. But he is also extremely prone to causing the others around him to change and the best example of this would be Shouto. Shouto let his anger over the abuse he suffered blind him and stunt his growth as a hero- he refused to use one half of his power out of spite. Izuku managed to cause him to not only remember a repressed memory but helped him overcome his anger and allow him to get second place in the tournament. As a bonus he also helped Shouto break out of his shell and form bonds with those around him instead of focusing on shaming his father.
"Manipulating, Converting and otherwise Controlling their Aspect, they are adept at shaping their powers and shifting them to suit them in battle."
Izuku has done this twice in the series- the first time was when he was still learning how to control his powers- instead of trying to punch and kick he'd instead try to use as little of his body as he could but in such a way that he still immobilized his opponent, and then when he had to change his fighting style- he had to completely change from using his hands as his defense to using his legs- meaning he had to teach himself an entirely knew fighting style. 
"And as change permeates their lives, these tend to build up and escalate towards a defining moment or series of defining moments that truly alter them, and that will shape who they are and how they interact with others."
and this is one of the many reasons why protagonists tend to be heirs. Because as an heir their life leads up to one moment that changes everything- which is exactly what being a protagonist is about. We all know what this moment was for Deku. It's the entire reason the series happened in the first place; All Might telling him he can be a hero.

Summery: Izuku Midoriya is most likely an Heir of Hope in my mind.
