Unfortunately not in my setup, but that's just because I don't have the money to upgrade it at the moment and nearly everything I have is stuff I can easily redownload.

Once I can save up for it I will up my storage and get some back ups set up.

As far as move sets go, you could always base them on things about the animal for animal based mascots. Like an ice slide for Tux, a charge for the GNU mascot, a long distance tongue grab for the KDE mascot, etc.

Also, as far as characters go, you could always include any public domain characters, like Frankenstein's Monster, Dracula, Steamboat Willie, Winnie the Pooh, etc.

Like others in here, I also set mine up with Debian and docker compose. Since it's an always on server I wanted maximum stability. I don't use unRAID, so not sure about compatibility for that.
