Smile

Smile (スマイル) is the Quirk used by Shinjiro Hohoemi.

Description
This Quirk allows the user to force other people to laugh uncontrollably for two hours. The user activates this Quirk by showing their teeth to the victim, it also works if the user's teeth are seen in a mirror or on video, as long as they are seen in real time.

This state of uncontrollable laughter incapacitates people, as they are barely able to move, let alone fight, as long as they are laughing.

This Quirk can also affect machines such as robots, though rather than making them laugh, it will simply cause them to short circuit and break, as it did with Power Loader and Mei Hatsume's capture robot.

Weaknesses
This Quirk has no effect if the target's vision is obscured, meaning that someone can face the user if they don't have to rely on their eyesight. By extension, this Quirk isn't effective at a far enough distance.

Trivia

 * This Quirk is very similar to Outburst, the Quirk used by the Smile Hero: Ms. Joke.
