It is a fan-given name as substitute for lack thereof, and should not be considered as part of the Attack on Titan universe.
The Smiling Titan is very tall, with long black hair. Its main distinguishing feature is its characteristic, a grinning smile in which its lips are fixed wide open, exposing its teeth and gums at all times.
After the Colossal Titan breaches the outer Wall, the Smiling Titan is among the many Titans that invade Monzen District. Maneuvering through Monzen, the Titan picked up and devoured a civilian man by biting his head off. Eventually it came upon Mikasa, who had been abandoned in the street while trying to rescue an infant. Although the Titan tried to eat Mikasa, it was only able to devour the infant that was with her, while Mikasa escaped. However the Titan was still able to bite her leaving a large disfigured scar on her stomach. Eren however believed the Smiling Titan succeeded in devouring her, as the church he was watching helplessly from collapsed and both were gone by the time he escaped. His belief that the Titan succeeded became one of his driving motives for joining the Survey Corps.
2 years later when Eren partook in his first mission and discovered Mikasa alive she revealed what really happened to her, and showed the scar she now had. When Eren unlocked his Titan ability and began slaughtering every Titan nearby the Smiling Titan was among the other Titans nearby while Eren's slaughter occurred. After killing almost a dozen Titans, the Smiling Titan and the other nearby Titans wondered away from the scene.
When Eren is kidnapped by Shikishima, he was taken to his secret bunker and he shows Eren the true nature of the Titans existence, the result of a military experiment 100 years ago to create human weapons. However, an outbreak began and numerous people in different countries started getting exposed, uncontrollably turning into mindless Titans. The woman who would be transformed in the Smiling Titan presumably being among them.
When Hans led the remaining Survey Corps soldiers to seal the hole Jean spotted 9 Titans roaming the fields some miles away, the Smiling Titan included. However Hans insisted they continue with their mission to ignore them, and none of the Titans spotted them.
- One unnamed adult male
- One unnamed infant
- The Smiling Titan appearing to kill Mikasa is reminiscent of Dina Yeager, as a mindless Titan, killing Carla Yeager, as in both instances this event motivated Eren in both forms of media to join the Military and eventually the Survey Corps.
