His hair becomes a lighter shade of green while standing on end, his body emanates green electricity arcs and an aura. Also, he flies by kicking off the air, which is made more explicit in the anime.

In the Western fandom, he's also frequently referred to as "Grape Gremlin", "Diaper Baby", "Diaper Gremlin", "Rat Boy" or "Rat Bitch" (and variations thereof), due to his short height and (in the eyes of some fans), his annoying nature, or "The Grapist", referencing a The Whitest Kids U' Know sketch.
- "Daft Punk" is one for Sero, due to the helmet on his hero uniform looking similar to the head of one of the two robots from the band Daft Punk. Alternatively, it could be "Tape Punk," alluding to both his Quirk and said Daft Punk reference. There's also "Captain Office Supplies".
- Due to Tenya's family name being occasionally being misspelled as "Lida" by some English speaking fans, some fans jokingly call him Linda in response to this.

Eventually, he also got "Shiggy". There's also "Bad Touch Man" as inspired by Jello Apocalypse. "Shigaraki Jr." came about following the reveal that "Shigaraki" is All For One's last name that he passed on to Tomura when he first took him in. Likewise, All For One has occasionally been referred to as "Shigaraki Sr." And “ShigAfO” for All for One trying to fuse with Shigaraki.

- Kaminari got saddled with the nickname "Traitor-Kun" due to the fan theory that he's been in league with Shigaraki.
