I must admit the main reason I love Ben 10 is because of Anodites- they are just such elegant aliens! I'm quite excited to have made my first animation- I may use it as a profile picture.
I know Gwen's powers have been drained before and (when she was first drained by Morningstar) her mana turned black then broke.
That gave me some inspiration to come up with an Anodite that has been drained dry before being broken out of her body. I don't think she would die, she would just learn to utilize a different power source and become a different species of Anodite. I'd imagine they would use something like dark matter instead of mana which is why she is black/ dull purple in colour.
However I think they'd be quite sad beings because they would loose their sense of self. I have drawn this one without a mouth as I think they would loose their speech and become more animalistic.
