I think the most annoying ones are whatever little bitches have the nerve to tell Homestuck fans to stay away from anime conventions because Homestuck isn't anime--and then toddle off to gush over all the Avengers, MLP, Dr. Who, Batman, Star Wars, Disney and Once-ler cosplayers at the exact same cons.
My next conventions and events:
Fan Expo 2018
Mr. Mayor (Animal Crossing: New Leaf) - 2018
Underswap Papyrus - 2018
Trickster Mode Equius Zahhak - 2018
L - 2018/2019
Future cosplays in the works:
Charlotte Mont d'Or - AN 2019
Rule 63 Aradia Megido - 2019
Rule 63 Rarity - 2019
Penelope (Sly 3)
Slice (Fighting Foodons)
Soap may be a four-letter word, but use it anyway.
