if I ever created a popular, mainstream character, I would probably analyse all the "character holding sign" memes featuring them to critique how on-character they are.
"sorry, Sammy the Super-Squirrel would never use the term 'sick' as an insult" "Zooglegorp the Alien is NOT a trans ally, he is the villain after all!" "Karl Koala Jr. isn't an artist or fan of any artists and therefore has no opinion on the harassment of fan artists, a better character to put across that message would be Basking Shark Bertha, who is an artist and animator herself."
(note that none of these characters exist, they're just names I came up with on the fly.)
(I'd hate to be Matt Furie)
