I couldn't fit every annoying character on here, so I decided to pick 2 out of 4 franchises I like.

From left to right (top to bottom for the 3 on the right):

Birdley (Deltarune)

Stella Goetia (Helluva Boss)

Balloon Boy (Five Nights at Freddy's 2)

Bubbles (The Amazing Digital Circus)

Mimzy (Hazbin Hotel)

Chica's Magic Rainbow (Five Nights at Freddy's World)

Serial Designation J (Murder Drones)

Annoying Dog (Undertale)

Everyone except for Stella, J and Annoying Dog is supposed to look... different... in a way.

Birdly is supposed to look Gigachad-ish, BB originally was supposed to look like he is dying from laughter but ended up looking like Tom Cruise from Family Guy lol, Bubbles is supposed to look slightly more creepy, Mimzy is supposed to look derpy and Chica's Magic Rainbow is, well, ugly...

Also J is grumpy because she's upset that I made her part of the club. That's what you get for being such a meanie, J! >:)
