Levi Ackerman is one of the most popular characters in all of the hit shonen anime Attack On Titan. He's counted among the protagonists, although with the labyrinthine lore and the twisting social relationships in the series, is a very loose term.

For as much as we know about him, there are also tons of facts about Levi that remain shrouded in mystery, from his exact age to his origins as a person with some of the best Titan-fighting abilities in the franchise. He's considered the strongest that humanity has to offer, making him completely indispensable in the fight against the titans.

10 How Old Is Levi?

While fans haven't ever gotten a read on how old Levi is exactly, they know his birthday which is December 25; this might be a pretty heavy-handed hint at some sort of "chosen-one" idea. That being said, fans have gotten pretty mixed signals about his actual age. Originally, they were told he's in his late 30s, then told he's in his early 30s which is the official statement from the manga creator.

When it comes to popularity polls, the Ackermans always tend to come out on top. Mikasa and Levi both are incredibly popular characters, although the popularity of Levi has dropped over time. At first, and in the second popularity poll that was conducted, Levi ranked first almost unanimously, which only makes sense given how cool he is. After that though, for whatever reason, he dropped down to third.

8 Why Doesn't He Get Drunk?

Maybe it's just an indication of how powerful Levi is, or maybe it's some of the Titan DNA that's in his bloodline, but despite the fact that Levi drinks alcohol for celebrations and the like when the situation warrants it, he never actually gets drunk.

This is probably for the better since it most likely benefits him to have a clear mind at all times, but the fact that he's so strangely hearty isn't ever explained satisfactorily.

7 Why Is He Such A Neat Freak?

One of the biggest traits fans see in Levi is the fact that he's a neat freak, who pretty commonly makes value judgments about other Titan characters based on how neat or sloppy they are. Either way, this is explained as being due to the fact that he was raised in the Underground, constantly being surrounded by filth and grime. He grew up longing for a clean home, and as a result, he can't stand the sight of dirt.

6 How Does He Like His Tea?

Weirdly enough, fans have got plenty of statements from Isayama (the author of the series) about how Levi likes to drink his tea, perhaps his favorite drink at least in the manga since he's shown drinking it frequently. In fact, Isayama thought it was important that fans know that if ever Levi were to lead a different life rather than the one he currently lives slaying Titans, he'd really like to open a tea shop.

5 Why Does He Wield His Sword So Strangely?

One of the things that fans of the series will notice about Levi's fighting style right off the bat is that he has a very idiosyncratic fighting stance, in addition to holding his sword in a rather strange fashion.

He holds his sword backhanded in his right hand, causing his sword to protrude from behind his back instead of holding it in front. Instead, he holds it this way so that he can utilize spinning attacks.

4 Why Isn't He Close With The Other Ackermans?

Something that's always puzzled fans about Levi is that he doesn't have a great relationship with anyone else in his family, despite the fact that growing up in the underground and dealing with the problems of the Titans constantly around them might have put a strain on those relationships. He frequently clashed with Mikasa earlier on in the series, but fans later see that this grudge has been done away with.

3 Why Is He So Powerful?

There are a few things that go into the strength Levi shows throughout the course of his fights with the Titans and with a lot of the humans who cross him.

One of them is the fact that his bloodline is actually bred to have the strength of Titans while being able to remain human rather than gradually transforming into the things he hates most. The other one is the fact that he trained with Kenny, a well-known monster with a knife.

2 Why Didn't He Become Evil Spending So Much Time With Kenny?

One of the things that doesn't quite make sense about Levi is the fact that he spent tons and tons of time with Kenny Ackerman, who's later revealed to be Levi's uncle. Kenny is well-known for being an absolute beast of a man, who values power over human life and pretty much anything else a good human is supposed to care about. Somehow, after being basically raised by Kenny, Levi manages to stave off the same motivations.

1 Why Doesn't Levi Sleep?

Some fans have noticed that Levi really doesn't get much sleep whatsoever. He's frequently shown up at night, whether he's actually on a mission or not. Even when things are more or less safe, audiences see Levi only gets 2 or 3 hours a night. One of the reasons that he doesn't sleep much is that he's an insomniac, but he also just views sleep as a non-event, a waste of time, despite the fact that it's necessary to human survival.
