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.
As the protagonist of the series, Eren is everything one wants in a hero. He's brave, loyal, and fiercely determined to win the war against the titans at all costs. Like most characters. He's motivated by the losses he's sustained in the war, primarily that of his mother.
There are so many great characters in AOT, but these are the ones that stand out as the most popular with fans. Levi has especially become the most likable character in the series, and fans are eagerly awaiting his return!
1 Levi ( 86,920+ Favorites)
A certified badass titan slayer, and quite possibly the coolest character you will ever meet in the anime verse. Levi's position as the best boy of Attack on Titan is very much deserved. No other character even comes close to him with that regard.
Levi's fighting skills are also cited as one of the reasons for his popularity. His skills with ODM gear are largely unmatched by everyone else in the series. He wasn't given formal training on it like the other Scouts, so it's impossible not to respect his skills.
Bertolt Hoover
Bertolt has been in love with Annie since they were children, and both were Warriors from Marley alongside Reiner. It's unknown if Annie knows about Bertolt's feeling towards her.
Out of all of his friends, Eren loved Mikasa the most and had romantic feelings for her. He saved her and helped avenge her parents from human traffickers when they were children. After that, Eren's family adopted her and she did everything that she could do to help him.
1 Levi Ackerman
Levi was not only one of the strongest but one of the most intelligent characters too with great strategic thinking skills and thanks to his unique way of thinking and his deadpan humor, the best Levi quotes are still AOT fans' favorites.
In the Junior High anime it is heavily implied that Annie has a crush on Eren and the two of them bond over their shared love for cheese burger steak.
In the popular parody series A Slap on Titan by Tom Andre, Armin falls in love with Annie and describes himself as the 'Crimson King' and Annie as his 'Dark Queen'.
It was made obvious throughout the story that Bertholdt held affection for his fellow warrior Annie Leonhart.
4) Hange Zoe
He chose her due to her intellect and leadership qualities. Hange is a prodigy when it comes to studying Titans and their skills. Despite many being opposed to her plan to capture Titans alive and perform experiments, Hange received the go-ahead and devised a plan to do the same.
The mighty female Titan in Attack on Titan
In Season 1, fans witnessed the Female Titan, who was none other than Annie Leonhart. She was responsible for killing a good number of people in the Scout Regiment.
Rico Brzenska (リコ・ブレツェンスカ Riko Buretsensuka?) is the team leader (班長 Hanchō?) of Squad Rico and a member of the Garrison's 1st Division Elite Forces. She is the only surviving leader of the Alpha Squad assigned to protect Eren Yeager during the liberation of Trost District.
Isayama has noted that he gave Levi a similar stature to Rorschach and gave him an obsession with cleanliness to contrast him with Rorschach's uncleanliness.
Many women love Levi because of his compassion, loyalty and constancy. They love him because he lifted up Hange when she felt insecure. Because he devised a way to protect Eren while Eren was still learning to control his titan power.
