Vikki is Slafer's Great Great Great Aunt, who is supposedly very creature-like. She is the creator of Slaferade and owns a cat named Sloodterna. She, like Slafer is over 500 years old. Although she has not actually appeared in an episode, it is assumed she will be. Vikki is also a relative of Orson, so it is possible that she may be a Wilderness Explorer.
