Here’s another couple pretty random Fandom wikis that I came across just recently. Linking the specific pages I landed on them at.

https://allspecies.fandom.com/wiki/Bogdanoff_Twins

A fandom wiki about “all species” and it has just short of 1k articles about everything from these two guys to fictional species such as Alien.

https://monstercat.fandom.com/wiki/Crab_Rave

This one is specifically about the music label Monstercat. It has about 4k pages.
