Angel is an alternate identity of Foop, used in order to break Chloe's kindness. Even though Foop is only 2 years old, Angel is in the form of a 10-year-old popular Elementary School kid. She sounds almost exactly like Foop, but slightly higher and with a stereotypical teenage girl voice.
She acts rude, just like her original identity, as she intends to steal all of Chloe's friends and make her look bad.
Being a disguise of Foop, she looks very similar. As she is an Anti-Fairy, she retains the pale-blue skin. She has the same Amethyst-colored eyes just like Foop, with more feminine eyelashes, along with fangs. Also, she still has his goatee and "F" shaped hair, but it is now in the form of a pony-tail. She wears a dark blue dress and sandals, with a heart-shaped pendant.
The power in Anti-Fairy World is being drained, all because of Chloe Carmichael's kindness. In order to restore the power to Anti-Fairy World, the Anti-Fairy Council summons Foop and commands him to break her kindness, making Chloe go from good to evil. In Foop's response, he grabs a magical to-die-for heart shaped pendant and transforms into a female.
Timmy is shown to have a crush on her. After he found out that he was actually Foop in disguise, he was disgusted as he kissed him.
This is also the second time Timmy kisses someone without knowing, the first was in Finding Emo where Timmy kisses Cosmo in a Missy disguise.
