Levi, a character from the popular anime/manga series Attack on Titan, is shown to be in a wheelchair in the later chapters of the manga. While there is no explicit explanation given for why he is in a wheelchair, there are several theories and hints that suggest possible reasons for his condition.

One theory is that Levi’s injuries were a result of his battles with Zeke, a member of the Beast Titan. Throughout the series, Zeke is shown to be a formidable opponent with the ability to control other Titans. Levi, being one of the most skilled fighters in the series, has had numerous battles with Zeke, and it is possible that he sustained injuries during one of these encounters that resulted in him being confined to a wheelchair. Additionally, there are hints in the manga that suggest that Zeke may have intentionally targeted Levi’s legs during their battles in order to disable him.
Another theory is that Levi’s injuries were a result of his actions during the final battle against the Titans. In this battle, Levi is shown to be fighting alongside the other soldiers, and it is possible that he sustained injuries that left him unable to walk. This theory is supported by the fact that Levi is shown to be wearing bandages on his legs in some of the later chapters of the manga.
It is also possible that Levi’s injuries were a result of his aging. While Levi is shown to be in excellent physical condition throughout the series, he is also shown to be aging. In fact, in one of the later chapters of the manga, Levi remarks that he is getting too old to fight. It is possible that Levi’s body simply couldn’t keep up with the demands of battle as he got older, and that he sustained injuries that left him unable to walk.
Regardless of the cause of Levi’s injuries, it is clear that his condition has had a significant impact on him both physically and emotionally. In the manga, Levi is shown to be frustrated and angry about his condition, and he is often shown lashing out at those around him. This is understandable, given that Levi is a character who has always prided himself on his physical prowess and his ability to fight.
However, as the manga progresses, Levi begins to come to terms with his condition and finds new ways to contribute to the fight against the Titans. For example, he becomes an advisor to the new generation of soldiers, using his vast experience and knowledge to help guide them. He also becomes a mentor to Gabi, a young warrior who is struggling to come to terms with her own experiences in the war.
In conclusion, while there is no definitive answer to why Levi is in a wheelchair, there are several theories and hints in the manga that suggest possible reasons for his condition. Regardless of the cause, Levi’s injuries have had a significant impact on him both physically and emotionally, and he has had to find new ways to contribute to the fight against the Titans. However, despite the challenges he faces, Levi remains a beloved and respected character in the Attack on Titan series, and his determination and resilience continue to inspire fans around the world.
