Eclipse was born in the Shadow Underworld, like Dark . Eclipse was a happy guy and soon went to school to study. He then went to high school and dropped off. Eclipse met Dark and started dating. After Dark built his secret base in Neighborville, they started living there. But of course, Zomboss had other plans.....
Eclipse was killed after Green Shadow destroyed him. He could sadly not come back and it was over. He had a good life, and still watches us from the skies.
