Susie Vortex is Cindy's aunt, an award-winning athlete, and a Olympic buff chick model (appears in episode Maximum Hugh). Although her name suggests that she is Cindy's paternal aunt she actually bears a striking resemblance to Cindy's mother Sasha, which doesn't make sense, since it is likely she might have married a relative of Cindy's father. In Maximum Hugh she impersonated Cindy's mother at a field day so Cindy could cheat to win, but Jimmy figured out the truth when he noticed "Sasha" having a slightly different height and a zipper on the back of her neck. She is voiced by Megan Cavanagh.
Trivia
- She makes a cameo appearance in "Maternotron Knows Best". You'll see her in the exercise area of the spa that Judy Neutron goes to.
