In Attack on Titan, Titans are creatures that pose a huge threat to humanity. In the year 845, these giant creatures breach a wall meant to keep them away from mankind because of a hole created by two unique Titans, the Colossus and Armored Titans. This results in the passing of many people, including Eren Yeager's mother. A few years later, Eren trains with other humans to fight against the Titan invasion. He befriends Reiner and Bertolt, two guys who also seem to hate Titans. 

During a battle to defend humanity, Reiner reveals that he and Bertolt are actually the Colossus and Armored Titans, the very same Titans responsible for the breach at Wall Maria and the tragic passing of his mother. The deception is jaw-dropping, and sends Eren into a fit of utter rage.
