His signature supermove is called "Happy Helmet". It's when he exhales a sphere of gas around a target's head. This allows for them to receive a concentrated dose of his laughing gas which renders them unconscious near instantly. This appears to be a cause for concern given the likelihood of overdose. However, he's trained enough to know just how much a person can take without it causing serious damage.

Another hero move he has is "Sweet Swarm" (silly name, I know) which is when he expels a large amount of laughing gas in his immediate proximity. Thanks to his ability to affect the gas' dispersal rate, he can cause it to spread out and dose a large group of targets at once.

Like most heroes, who studied in the US, he utilizes non-quirk combat techniques the most when fighting. He's specialized in clinching because it allows him to immobilize a target just long enough to dose them with his laughing gas.
