Gabi's accomplishments are nothing short of incredible, and she becomes one of the most valuable members of the combined resistance group that rises up to take out Eren. She's the one who's responsible for initially shooting off Eren's head and nearly ending his reign of terror before he can initiate the Rumbling.

Sasha's zest for food becomes one of her most endearing traits and an important reminder that every soldier in this war is a real person. Sasha's unexpected death is a crucial catalyst for Eren and company, and she goes out as a brave martyr.

Practically every character in Attack on Titan experiences tremendous growth since the start of the series, but Armin's metamorphosis is especially impressive. Initially, Armin comes across as the most passive and precious member of Eren and Mikasa's group of friends.

Armin struggles to find confidence, but he fully comes into his own when he's chosen to become the Colossal Titan over Erwin and shoulder the responsibilities that come with this. Armin doesn't waste this new power and his contributions in the final seasons are vital to the heroes' survival. Erwin Smith would be proud.

The heroes in Attack on Titan face so many casualties by the end of the series, which affects everyone in different ways. Jean Kirstein is a decent supporting player of the Survey Corps who actually convinced many of the soldiers to enlist in the first place.

Jean survives while others fall, and it causes him to mature into an impressive leader during the final battles for humanity. Jean never gives up, and his fearlessness when it comes to protecting others and fighting for what he believes in turns him into a surprising highlight of the last season.

Mikasa Ackerman is just a fragile orphan at the start of Attack on Titan, yet she endures multiple trials by fire and hardens into a revered fighter who's at the top of her trade. Mikasa is an emotional character, and the somewhat toxic codependency that she's formed with Eren becomes a challenging cross to bear.

Mikasa's complicated feelings don't cloud her head in battle, and her skills are nearly on par with Levi's. Mikasa needs to really search her soul after Eren transforms into the Founding Titan, but she comes out of the other side stronger.

3 Eren Jaeger Changes The Face Of History Through His Bold Actions

The greatest magic trick that Attack on Titan pulls on its audience is how its put-upon protagonist, Eren Jarger, grows up to be the greatest danger to humanity. The beauty of this transformation is the slow, believable manner in which it plays out.

Eren searches for identity, purpose, and strength throughout the series, ultimately setting him down a dangerous path where he's willing to scorch the Earth and start over. As a hero or as a villain, Eren proves himself to be a strategic genius, and he ensures that Attack on Titan is always entertaining.

2 Reiner Braun Has Overcome Impossible Odds For His People

Reiner Braun, also known as the Armored Titan, is one of the first enemies in the series who really make matters personal for Eren and company. Reiner is terrifying in his Titan form and a fair match for Eren, but the series carefully paints parallels between these two. Reiner gains immense depth, and his actions become much easier to understand.

In a certain context, there's even a strong case to be made that Reiner is the show's hero. Reiner, like many other Marleyan Warriors, is able to look past his people's history and join the fight against Eren.

1 Levi Ackerman Is The Top Titan Slayer

Many competent fighters have emerged in Attack on Titan, but early on, Levi Ackerman is presented as a wunderkind with nearly God-like abilities when it comes to Titan slaying. Levi is responsible for many of the series' most exciting action sequences, and he's slaughtered innumerable Titans.

Levi's battle theatrics are hard to top, but he's also the stoic type who doesn't waste words and can effortlessly inspire his fellow man when necessary. The final season of Attack on Titan largely has Levi covered in gnarly bandages and almost mute. However, even in that state, he's still able to command authority and exude confidence.
