Felicity was slaved in a very young age. When her mother died working on the field, she was sold by the Gordanians. Felicity's new job was a harem dancer on Slagg. The Omega Men came to Slagg and liberated it from Gordanian control. Felicity used the chance to escape the world with the team. During the travels with the group, felicity fell in-love with another Karnan, Tigorr. Felicity was one of the casualties in Invasion.
Recently Felicity has returned, with a different look, now dark-furred and no tailed feline. She has gained darkness powers and calls herself Nimbus after her old friend.
