I myself am not the biggest fan of the type of humor that is most commonly in these fandubs (excessive swearing and all kinds of inappropriate jokes), but just the way they're presented and acted in this absolutely ridiculous, i love it so much. If you have a handful of hours, you need to watch these. I've only seen the sonic ones, but i don't doubt the others are just as funny. (the shadow one is the funniest i've seen)
p.s. - if you're familiar with tiktok enough, there are some audios that were viral at some point a while ago you may recognize (specifically from SA2's dark story fandub) i challenge you to go find them >:D.
