Attack on Titan is a story-rich anime and manga series centered around Eren Yeager. While other characters play massive roles in the plot, none are quite as pivotal as the Attack Titan himself. Eren is a complex character who feels compelled to bear every burden himself, not letting any of his friends share the blame.

His friends, however, are smart, caring, and devoted. Each of them brings something unique to the story through their distinct personalities, fears, and goals.

While Attack on Titan is unequivocally Eren's story, many of his friends could have their own spinoffs. Characters like Armin and Mikasa have incredible backgrounds and promising futures, making for a decent tale inside or outside the Walls. Even some of Eren's enemies have interesting backstories that could be explored further, giving further insight into the world that is Attack on Titan.

10 Ymir Fritz

The Story of the Original Titan

Ymir Fritz is one of the least talked about figures in Attack on Titan, especially when you consider how important she is to the story. It makes sense though, given the fact that she lived about 2,000 years before Eren and his friends. Ymir was a slave to an Eldian King for most of her life. She was being hunted for sport when she found the Source of All Living Matter, which gave her the power to transform into the first ever Titan. Unfortunately, the Eldian King Fritz continued to enslave Ymir and used her Titan powers to build his kingdom and destroy his enemies.

While Ymir's story is mostly told in Attack on Titan, a spin-off detailing her life as the first ever Titan would be very interesting. It would be even more interesting because she lived 2,000 years before the main story takes place, giving people a glimpse of the world of Attack on Titan before the Titans.

9 Zeke Yeager

Eren's Brother Lived a Twisted Life

Zeke Yeager, like his brother Eren, has lived a very complicated life. He's fought for both sides, has a tumultuous relationship with his dad and brother, and doesn't know what he truly wants. He was raised harshly by his dad, Grisha Yeager, before he became a Titan himself. As the Beast Titan, Zeke was cold, calculated, and cunning. He was everything the Marleyan military needed him to be when he assaulted Paradis. As a friend to his brother, Zeke almost ended the world.

A spin-off about Zeke Yeager could have a lot of different angles it could tackle. It could cover his time as a child, growing up with one of the worst dads in anime. It could also cover his time as the Beast Titan, even showing his perspective of the fight against Erwin Smith and Levi Ackerman. No matter what time period of Zeke's life his story takes place in, it would be filled with deceptive twists and turns at every corner.

8 Falco Grice and Gabi Braun

Two Young Kids Who've Seen Both Sides of a War

Falco Grice and Gabi Braun have had it tough as kids, but just about everyone has in the world of Attack on Titan. Like Eren, they watched as their homeland was invaded brutally by Titans. While they are supposed to be enemies of the Eldians, they share a lot in common with them. A spin-off series about Falco and Gabi would be interesting to see even more from the Marleyan perspective. It would also be nice to see Gabi and Falco grow up and live in their new

Titan-free world. As Warrior candidates and soldiers, they know exactly what the battlefield is like, but a spin-off where they're not fighting might be great too. Watching Gabi let go of her hatred of the 'devils' on Paradis was an incredibly cathartic moment. It showed that Gabi is much smarter than she lets on, making her worthy of an exciting spin-off.

7 Reiner Braun

One of the Most Internally Tortured Characters in Attack on Titan

Reiner Braun was tasked with one of the worst jobs anyone could have. He was sent to Paradis island as a small boy to retake the Founding Titan for his home country of Marley. To do so, he broke down the Walls protecting innocent people from Titans. His story is one of the most conflicting in Attack on Titan. Reiner did horrible things, but was a brainwashed child when he did them. He grew up riddled with guilt and eventually asked Eren to kill him for what he did.

A spin-off about Reiner would be bleak, brutal, and very interesting. It could show him either training to become a Warrior in Marley as a child, even more than the series already did, or it could show his beginning days on Paradis. Even as an adult, Reiner fought hard to protect those he cares about. He might be good, he might be evil, but a spin-off about Reiner Braun would definitely be interesting.

6 Annie Leonhart

The Female Titan Is a Strong Fighter and an Interesting Character

Annie Leonhart is a character shrouded in mystery for most of Attack on Titan. She's hard-headed, devoted to her cause, and one of the best hand-to-hand fighters the Survey Corps has ever seen. She's so good at fighting, she inadvertently taught Eren how to judo toss. While she's an antagonist for most of the beginning of the series, her change of heart is one of the best subplots in the series. A spin-off about Annie could further explore her doubts about being a Warrior.

It could also go into her four years of hibernation while she was comatose in her crystal. Armin came to visit her a lot during those four years, and a spin-off about those meetings could be cute and weird all at the same time. After the war is over, Annie's story could have a lot to tell as well.

5 Armin Arlert

Eren's Best Friend Is also a Tactical Genius

Armin is Eren's best friend throughout Attack on Titan. He's a soft-spoken boy who doesn't want to fight unless he has to. He's had a lot forced on him since the Walls have come down, and he's done pretty well, all things considered. As the Colossal Titan, Armin is capable of nuclear explosions every time he transforms. As the 15th leader of the Survey Corps, he commands the remaining troops against none other than his best friend Eren.

No matter what era of Armin's life the story takes place in, it would be interesting. A spin-off could cover Armin's first days after Eren's death, rebuilding Paradis and the world that his friend destroyed. It could also go into Armin's romance with Annie more and see if the former cadets could have a good life together.

4 Kenny Ackerman

He Makes the Story Exciting Every Time He's In It

Kenny Ackerman is a wildcard. He's Levi Ackerman's uncle and even taught the young Captain everything he knows. He's also a serial killer who went after Kenny as soon as someone told him to. He leads a squad against Levi and the Survey Corps during the second half of the series and is a general pain for everyone thanks to his skill. Kenny wants power more than anything else. He befriended the King of the Walls, Uri Reiss, and really only wanted the Founding Titan's power the entire time.

A spin-off about Kenny Ackerman could shine light on Levi's time as a youth in the Underground of the Walls. It could also show the Underground as an area more, as the main story didn't really touch on the undercity where a lot of characters come from. Whatever spin-off Kenny finds himself in would be funny, violent, and probably a little crazy.

3 Mikasa Ackerman

A Story About Mikasa's Relation to the Azumabito Family Would Be Great

Mikasa Ackerman is one of the Attack on Titan. Not only is she a force to be reckoned with on the battlefield, but off of it, she's a great friend to Eren and the rest of the Survey Corps. She's also one of the quietest characters around who speaks with her weapons more than her words. A spin-off story about Mikasa would be very interesting and could cover one of the many areas of interest in her life. Mikasa is a descendant of the Azumabito family, a powerful political family from the country of Hizuru.

Hizuru is the only country in the world that recognizes and allies with Paradis as well, so it might be interesting to see Mikasa interacting with her distant family. Mikasa is one of the few characters that survived Attack on Titan, so a story about her life after the war would be interesting. While she was in love with Eren for most of her life, Mikasa's future endeavors are hers to explore.

2 Erwin Smith

The Man With One of the Best Speeches in Anime

Erwin Smith might be the most widely respected figure in Attack on Titan. As the 13th leader of the Survey Corps, Erwin led his people through the worst battles on numerous occasions. He's no stranger to danger and will do whatever he can to protect his troops and the people of Paradis. When the Beast Titan comes to Paradis, Erwin Smith leads the defense. Unfortunately, there isn't much of a defense against an enemy that can sling rocks from miles away.

The Commander of the Survey Corps realizes that his troops have one option: charge into certain death. He gives one of the greatest speeches in anime to his soldiers, invigorating them with the courage to die. A spin-off about Erwin Smith would probably cause the Beast Titan to quiver in his boots once again.

1 Levi Ackerman

Humanity's Strongest Solider

Levi Ackerman lights up the screen and page every time he's featured in Attack on Titan. He's humanity's strongest fighter and he's constantly proving it. As the leader of the Special Operations Squad within the Survey Corps, he's more than familiar with the toughest battles against the strongest opponents. Even when he's not fighting, Levi shows a coolness that attracts people to him. He's a good leader, a great fighter, and a person who will always hold a grudge.

His fight against Kenny Ackerman is one of the best one-man-army moments in anime. With dozens of people shooting at him, Levi glides through the city like Spider-Man. Facing the Titans, he's lethal. Even the Beast Titan stood no match against the Captain. While he received something of a spin-off in the past, seeing more of Levi in his prime would be the perfect way to bring back Attack on Titan.
