There are three things that I know about Sonic T. Hedgehog...

1. He was a hero, and I was a villain...

2. He saves people, and I hurt people and...

3. I think I'm in love with him.

(Name) the (animal type) was a villain, so was her best friend Tara. They were captured and Tara got roboticised by Eggman, an evil genius on their home planet. A blue hedgehog saved her from Eggmans and roboticised Tara's evil clutches and certain death. She lives with her speedy hero, aka Sonic, and his fluffy friend, Tails while she heals. Whilst there, she discovers a feeling she had never had before. Love. She gains feelings for Sonic T. Hedgehog, a hero. Sonic begins having feelings for (name), but doesn't know that she's a villain.

What does Sonic do when he learns that she's the villain?
