Plot
The story of Attack on Titan centers around the adventures of Eren Jeager, his adopted sister Mikasa Ackerman, and their friend Armin Arlert. After the wall which protects Eren's hometown is breached by Titans (giant humanoid creatures), including the 60-meter skinless Colossus Titan and the abnormally intelligent Armored Titan, a young Eren suffers the death of his mother at the hands of a Titan. Once Eren and his friends are evacuated from the district to safety, he vows revenge against all Titans and later enlists in the military, accompanied by Mikasa and Armin.

Fandom
This series has one of the most notable newer fandoms. While the series is serious and emotional most of the time, the fandom is the complete opposite. Attack on Titan fans often joke about Eren's obsession with Titans, Jean's horse-face, Marco's remaining half etc. Some of the fandom's favorite characters are Marco Bodt ("Freckled Jesus"), Sasha Blouse ("Potato Girl"), Corporal Levi ("Clean Freak"), Hanji Zoe (Shitty Glasses).
