Mikasa Ackerman
After learning more about each other, including the fact that they're related, they became great comrades. From the moment Mikasa graduated the 104th Cadet Corps, soldiers all around Paradis knew how strong she was, and by the end of the manga, she surpassed Levi's strength.
Erwin Smith is the Commander of the Survey Corps and the creator of the Long-Distance Enemy Scouting Formation. Erwin Smith (エルヴィン・スミス Eruvin Sumisu?) was the 13th commander (団長 Danchō?) of the Survey Corps.
After being kidnapped in her youth by bandits and subsequently rescued by Eren, Mikasa has pledged her life to her companion. Similarly, she protects Armin from street bullies. Because of this pledge, she is physically stronger than both the boys and is constantly beating up their enemies.
Armin is one of the few kind and pacifistic characters in Attack on Titan. As a child, he won't even attempt to lay a hand on the local bullies, even as they mercilessly attack him. As the series progresses, though, Armin doesn't have a choice but to accept some of the Attack on Titan universe's harsh realities.
Some of the most famous Marvel universe characters, such as Thanos and Iron Man, can easily beat the Attack on Titan protagonist.
1 Eren Yaeger
By far, Eren is the strongest character in the entire series. All that power, of course, comes from the many Titan forms he's acquired over the years.
When it comes to pure skill, Levi far outranks Eren. Not only does Levi have more experience in the field, but he's also just a better fighter overall. Without his ability to transform into a Titan on command, Eren wouldn't stand a chance against Levi.
Zeke Yeager, otherwise known as the Beast Titan or just The Beast, is the main antagonist of the Attack on Titan series.
2 Captain Levi Ackerman Boasts Of 58+ Titan Kills (And More Than A Dozen People)
Naruto and Levi may be equally matched in terms of physical strength thanks to the Ackerman's supernatural bloodline, but even with his many years of experience fighting titans, Levi has never faced anything like Naruto.
Goku. Goku is the main protagonist of the Dragon Ball franchise. His abilities include super strength, utilization of ki, teleportation, super speed, and durability. However, he is the strongest anime character because he overcomes adversity and thrives on improvement.
1 Levi Ackerman
He's arguably the best Ackerman in the anime. Levi's abilities allow him to excel in fighting not just titans but also human enemies. He's also the only non-titan character in the anime to take down a Shifter Titan single-handedly as was shown when he defeated Zeke in Beast Titan form.
1 Armin Is A Certifiable Genius
Armin Arlert is so smart that he makes other smart characters look dumb. Armin is the go-to guy for strategies, and his friends can always count on him to deliver them out of difficult situations. With his incredible mind, he's saved the day on numerous occasions.
Mikasa is a Powerful Ally
Mikasa saves Eren's life quite frequently. The second strongest ackerman, Mikasa seems to be steadily closing the gap between herself and humanity's strongest soldier.
Apart from the Eldian Titan Shifters, Eren has always had a long-standing rivalry with one of his comrades, Jean Kirschtein.
The soldiers concluded that, in order to halt the Rumbling, they must kill Eren Yeager by any means necessary. Returning to Eren's Titan, the allies launched their own counterattack on the Titans.
Founding Titan is the first and the strongest Titan of all the nine. If the Founding Titan is someone from Royal Bloodline, then it will possess limitless power. Eren Yeager was not someone of royal blood that's why he asked for Zeke's help to use the Founding Titan to its fullest.
Levi's popularity lies not only in his unmatched combative prowess but also in his undefeated charisma that none of the other characters could ever achieve.
