Odessa started off with humble beginnings; I was seeing what I could make as a Minecraft skin, and after rejecting a Stunfisk, I found Reuniclus to be pretty good (even though it has no legs but that didn't stop me)
Her signature weapon is the diamond axe, which can be enchanted for combat just like a sword, so that's what I did.

Over time, a character developed out of simply not changing the skin, and it's still hanging around today, though now with clothes on.

She has a completely sexless body, considering she's basically an amoeba. The cytoplasm can also be altered in small ways - she can stretch it in any way so long as her limb core masses stay in that same general shape. Usually she uses it to put little nubbly spikes in some places. It can extend considerable lengths.
The red core masses make it very easy to manipulate the cytoplasm around them, giving fine motor skills - this means she can roll up her horns if she wants, which looks very silly but I guess if she wants to stick them up someone's nose, there's that.

If any of the core masses are separated from her, they have a limited amount of time to be reintroduced before they will die. If this happens. she has to regenerate what was lost. As long as her head core is intact, she can regenerate her entire body, though losing a core mass is exceedingly painful.

And this is her theme song!
