Ms. Joke's Quirk turns a fight into a laughing fit. Outburst reduces villains to helpless giggling, dulling coordination and thinking at the same time, which makes arresting them trivial. The series has described it in detail but has never actually shown it land.
Outburst is an Emitter type Quirk belonging to Emi Fukukado, the Pro Hero Ms. Joke, and it reaches as far as her voice does. Readers know it only secondhand: Izuku Midoriya explains its workings, while the ability itself has never appeared in action.
By his account, anyone nearby is forced into laughter so violent that motor control and clear thought both collapse, which makes it handy for taking villains out of a fight. How strong it becomes at full stretch, and what limits it runs into, has never been established. The anime marks activation with a blue aura around Ms. Joke. Whether she must say something to set the laughter off, or it simply erupts on its own, is unclear.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Ms. Joke is the sole holder. Incapacitated targets make easy work for her, and she has been shown punching a villain already doubled over. The Quirk closely parallels Smile, used by the villain Mr. Smiley, and its laughter inducing effect invites comparison to the Joker Venom of DC Comics, though Outburst does not kill.
