Shape Shifter Mind Warp 5

My name is Todd Aldridge. At least, I think it is....

Where did I go?

I don't remember much about the night I disappeared. One minute I saw the strange light in the sky. The next minute I saw a strange light in the sky. The next minute I woke up in the hospital. The thing is, it wasn't the next minute. It was nine months later....

What happened to me?

Some people think I was kidnapped. Others say I was abducted by aliens. I don't know what to believe. But I know this: I'm not the same as before. I've changed. And I keep changing. Suddenly I make myself look like different people. Anyone I want. The only problem is, I'm forgetting who I really am.

Who am I?
