Looking for Vtuber design suggestions

Hi, I was wanting to make some vtuber concepts but I'm super stuck on the basic idea, and I was wondering if I could get some suggestions for what kind of vtuber Designs?

Originally I was thinking some themed around fish, or a tiger, or a skeleton, but then I figured those are probably all overused and while I dont mind using concepts that are already used, I just dont want to use anything thats oversaturated(like demons, wolves, foxes, cats etc), but I'm trying to think of something that might also catch some attention/I can make into a memorable design? I'm masc leaning non-binary, not sure if that helps.

If anyone willing to offer up some basic ideas that they don't see often or think would be fun to see more of, I'd be super appreciative?

Not sure what to flair this as, sorry. If this is the wrong place to post this, please let me know where I should be posting. Thank you!!
