Anti-Felicia

Anti-Felicia is the Anti-Fairy Cat to Trixie Tang and opposite to Timmy's Fairy Cat, Felicia. She is a black cat with an Anti-Fairy crown, bat wings and a blue, magical collar with the Anti-Fairy star on it.

History
She appears in the episode "Fairly Goth Pet", where the Tang family had enough of their yapping poodle named "Fifi" and decided to get a cat instead. Being trusted to get the cat, Trixie was about to make her way to the pet store, but notices Timmy Turner with his Fairy Dog and Cat. Intrigued that magical pets existed, Trixie ends up in the Anti-Fairy World Pet Store, who was run by the Grim Reaper. The Reaper then introduces Anti-Felicia to Trixie, who she found out was an Anti-Fairy Cat.

When finally brought home, the Tang Family fell in love with Anti-Felicia and enjoyed much of her company, except Trixie's mother, who preferred to keep Fifi.

Little did they realize that Anti-Felicia had a strategy to rid herself of Felicia once and for all, in which she demands the aid of Foop. Foop nervously agreed to help Anti-Felicia, but secretly teleports Timmy and his Fairies somewhere in Aisa (Hong Kong, China) and replaces them with life-like sculptures in Timmy's room.

After the dummies were taken care of, Foop casted a sleeping spell on Anti-Felicia and brought her back home, who convinces her that the events that took place were all a dream.

Anti-Felicia's Relationships
Relationship with Felicia As many Anti-Fairies, Anti-Felicia cannot stand her Fairy opposite and wants to destroy her mercilessly. However, she is under the rehibilitation of Trixie Tang and Anti-Cosmo.

Whenever she sees Felicia, her blood boils with rage and hisses at her. She also seems to hate Felicia's owner, Timmy Turner.

Relationship with Trixie Tang
Anti-Felicia grew to tolerate and slightly respect Trixie Tang and her band of Anti-Fairies. Anti-Felicia will only sleep on Trixie's bed and converse with Trixie in her room. Whenever she tries to destroy her archnemesis, Felicia, Trixie would get in the way and stop her. In response, Anti-Felicia will stop whatever it is she was doing. Where as if any one else gets in her way, she would either ignore them, for scratch them and continue on with whatever it is she's doing.

Relationship with Foop
Anti-Felicia sees Foop as a perfect henchman for pranks that involve Timmy and his Fairies. She dislikes the idea that Foop was rehibilitated and tries to persuade him into doing acts of evil.

Relationship with Anti-Cosmo
Anti-Felicia has little to no respect for Anti-Cosmo, considering that Anti-Cosmo isn't the pet type and the fact that Anti-Felicia can't stand his fits of irritation and lectures. To her, she sees Anti-Cosmo as nothing but a very irritable, floating, scratching post. There are tims where the two will get along, but otherwise, they can't stand being in the same room with each other.
