8. Susan gets abducted by aliens (ok, fine, ONE alien). He wants the substance that is making her big and strong (and I don't mean vegetables). What is this evil alien's name?
From Quiz Monsters Vs. Aliens
Answer:
Gallaxhar
Gallaxhar destroyed his entire home planet, along with all the people on it, because he got annoyed with his wife. He says he had a lot of childhood traumatic experiences growing up that we never got to hear about (but apparently we heard too much, according to Gallaxhar). Gallaxhar intends originally to pull all the quantonium out of Susan. When he does, he decides Earth is the perfect planet to take over. He clones himself several times, using the quantonium, and prepares himself to destroy all humans. He says he comes in peace, but when there is a giant holographic alien head outside, you tend not to believe him.
