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, the inheritor of the Beast Titan, is Levi's greatest enemy. The two have fought in many epic battles throughout the series and are very close in strength. In their first battle, Levi hesitated to kill Zeke, allowing him to escape when Pieck saved him.
At the beginning, Levi would for sure win as he is both more experienced and has great g-force tolerance, however, if you're talking about season 4 eren (warhammer power + attack titan) then titan eren would win.
3 Levi Cannot Kill Any Of The Founding Titans, Including Eren. There is a theory that no Ackerman, even though they are more than capable of doing so, will be able to kill any of the Nine Founding Titans, Eren included.
Levi Ackerman is considered to be the strongest character by many fans of Attack on Titan. He was known as humanity's strongest soldier at the beginning of the series and is as powerful as titan shifters despite not having any titan abilities himself.
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.
Unlike Mikasa, Levi was fully prepared to kill Eren and is even more qualified to do so. He was fast enough to adapt to pure titans even when they caught them by surprise, suggesting that he could remain well out of reach from Yeager's attacks just as well as Porco did.
58+ Titans 12 People
Captain Levi's record of Titan kills (58+) is yet to be beaten by any human, and he has killed more than a dozen people during the course of the story. Thankfully, he never has to waste another moment murdering people after the war's conclusion.
Unlike Eren and the rest of the leading cast, Levi is much more fleshed out and charismatic. It's easier to find redeeming qualities in Levi than Eren. He's not the typical "badass" often seen in fiction.
1) Thor. Regardless of the form Attack on Titan's protagonist takes, Thor Odinson can easily defeat him. Despite being in Attack or Warhammer form, Thor can easily call lightning down to the nape of the Titans, eliminating the form and Eren in the process.
The matchup between Levi and Tanjiro would be a close one. The young demon slayer has demonstrated an incredible amount of strength, speed, durability, and adaptability in the first season of the anime. Still, Levi approaches battle with a stone-cold efficiency that Tanjiro lacks.
1 Zeke Fought Levi Many Times Throughout The Series
Humanity's strongest soldier and the inheritor of the Beast Titan became each other's greatest enemy when they fought against each other in Shiganshina. Zeke had killed many members of the Survey Corps, including Erwin, and Levi failed to avenge them.
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.
Mike speaks of his faith in humanity to Nanaba. Mike Zacharias (ミケ・ザカリアス Mike Zakariasu?) was the squad leader (分隊長 Bun-taichō?) of Squad Mike, a major division of the Survey Corps. A trusted soldier, he was considered humanity's second strongest soldier after Captain Levi.
Eren and his peers fear Levi in the same way you might fear your math teacher: they wouldn't challenge him if they didn't absolutely have to, but that doesn't compromise their genuine respect and admiration for him.
Why did Levi beat up Eren? After it was found out by the humanity that Eren is actually a titan or could turn into a titan on his own will, they became scared.
He notices too late that Eren's Titan on the ground below is in fact merely its hardened shell, and in the moment of vulnerability, Eren, in his human form, strikes at the Colossal Titan, pulling Bertholdt from the nape as the Colossal Titan collapses in defeat.
As the Founding Titan, Eren Jaeger is the best chance that the world of Attack on Titan has to change the future. But just what power does he have? In the Final Season of Attack on Titan, Eren has gained the ability to transform into the terrifying Founding Titan and command a powerful Titan army.
Eren possessed the power of three Titans. From his father, Eren inherited the Attack and Founding Titans. After eating Lara Tybur during the Raid on Liberio, he gained the War Hammer Titan as well.
Pieck's Cart Titan is arguably the weakest of the Nine, but it comes with several advantages. Unlike its eight brethren, the Cart Titan walks on all four legs, making it an excellent method of transport. Pieck often has large structures attached to her back, which carry both people and weapons.
