I am sometimes have my off canon AU, but in that AU, I try my best to stick to the OG storyline. Some people go completely off the rails, shipping BakuDeku when Bakugo literally told Deku to kill himself!
Mine is Mina from MHA. Some people in the fandom made her a pick me and just ruined the character for me. Also, Ochaco Uraraka was good. Then the fandom made her a bratty woman whose only personality trait is doing anything for Deku. So yeah. The fandom can be really bad and toxic.
I love MHA, Vocaloid, FNAF and Gacha. I never fully express my love for them since people see them as “weird” and make fun of me for it. I am happy to have a place to talk to people about my interests without being judged.
