As stated, you can include all the general information.
You can also throw in a couple things that are unique or interesting about your character, like their scent, their favorite things to do, any physical abnormalities, even their theme song or what their voice sounds like.
The options are limitless!
Have fun with it! It's all about expressing your creativity! (:
I find a really good way to make your characters noticeable and make them pop is to have them be exotic species, not animals at all in the way of being sentient robots/Artificially Intelligent Computer Viruses/magic rocks/magic things or, if you aren't comfortable with tech, just do hybridized things or something. Then give them an interesting backstory mostly hinted at in the roleplay and only add it to the bio when something something as in "their secret is out."
Agreed! I love when those creative folks out there make up really cool and interesting new species. I always find them so interesting and I always want to make one.
