Katella is an intergalactic huntress who goes from planet to planet kidnapping rare animals to sell to zoos for a lot of money.
Katella came to Mobius to kidnap rare animals and sell them to zoos and Dr. Robotnik decided to cash in on it. When she saw Robotnik, she fell in love right away. Robotnik asked her to catch Sonic for him. After succeeding, she forced Robotnik to marry her, but the ceremony was interrupted by the very irrate Mama Robotnik. After a fight between the two evil women, Katella decided that she no longer wanted to marry Robotnik because she can't stand his mother, much to Robotnik's relief. She then left Mobius with the intent to find "a planet that really appreciates me."
- Katella is by far the most realistic-drawn character in the Adventures of Sonic the Hedgehog television series, unlike other characters that are much more cartoonish.
