— Foop, to Anti-Wanda (These are also his first words)
Foop Anti-Cosma-Anti-Fairywinkle is the Anti-Fairy counterpart and side effect of Poof and the son of Anti-Cosmo and Anti-Wanda. He is supposedly the first Anti-Fairy baby born in thousands of years, after his father Anti-Cosmo. His name is the same as Poof's, but backwards. He has become in one of the main antagonists of the series since Season 7 onwards. He first appeared in "Anti-Poof". It is possible that he has taken over his father's army of anti-fairies, since he is no longer seen leading them.
Foop appears in "A Fairly Odd Summer" in CGI, and also in live-action, played by Scott Baio. He's the first character other than Timmy's fairies to be rendered in CGI in the movies.
Since every Fairy has an Anti-Fairy counterpart, Poof's Anti-Fairy counterpart was born to Anti-Wanda and Anti-Cosmo, with the mother giving birth since in Anti-Fairy Pregnancy females do so, as opposed to males giving birth in Fairy Pregnancy. Because Poof is so nice and attracts so much positive attention, Foop is evil and is extremely jealous of his counterpart. Foop wants nothing but to destroy Poof, and he cares not for anyone who gets in his way including his fellow Anti-Fairies. Unlike Poof, who causes bad things to happen when he cries, Foop causes good things to happen when he cries. Foop is the only Anti-Fairy known to not have his name starting with the prefix "Anti-" (possibly due to no Anti-Fairies being born in milleniums as the Fairies decided not to have babies after Cosmo). Foop is also a lot like his father, Anti-Cosmo. He also suffers from a split personality; that of a kind and sensitive side opposed to his evil, maniacal self, to which he argues with on a regular basis. He would even kill Poof just to get him attention.
Foop resembles Poof, but he is shaped like a cube rather than a sphere. He also was born with a black mustache and goatee on his face, the kind typically seen on stereotypical villains or drawn on pictures as vandalism. It is interesting to note a goatee on a doppelganger insinuates its the evil one. His pajamas are slightly darker blue than his skin, and they have a skull symbol on them. Foop has bat wings and a black crown like all Anti-Fairies. His wand is a baby bottle with blue bat wings on the side, as opposed to Poof's baby rattle. He also speaks with a stereotypical British gentleman's accent like his father Anti-Cosmo, who apparently grew to dislike him soon after his birth. Foop's tears are also made of acid. He inherited the same set of fangs and pointed ears from his father, and has the same eyebrows and eyelashes his mother has.
As the series goes on, he has been getting more stupid and making mistakes that his mother would make. Some examples are: In Timmy's Secret Wish!, he didn't realize that he would disappear with Poof due to his uncontrolled arrogance. In When Losers Attack, he didn't notice that there was a spider on his tongue.
He was born by Anti-Wanda in the episode, Anti-Poof. The first sentence he said was "Hello Clarice, I mean mother." He wants to destroy Poof because Foop doesn't want to "share the spotlight" with him (he wants to be the only fairy baby born in thousands of years, not the 2nd.) His name is the word "Poof" spelled backwards which is because they are total opposites. He thinks Poof's name is more masculine than his own.
Foop didn't want to share the spotlight with Poof and aimed to destroy him, he set out to find Poof and conquer the world, but not before absorbing the magical power of the Big Anti-Wand in Anti-Fairy World and using his magic to turn Anti-Fairy World into a cute storybook land, and the Anti-Fairies (including Anti-Cosmo and Anti-Wanda) into stuffed animal like creatures. Foop also destroyed the planet Burger World when he learned they were selling Poof toys in their "Peppy Meals".
"I've waited my whole life for this moment! All 6 Hours and 45 Minutes of it!"
Tracking Poof to Fairy World, Foop proceeded to drain away all the color and magic from the landscape and Fairies, even Jorgen. Luckily, Cosmo, Wanda, Timmy, and Poof managed to escape to Earth before they could be affected. Foop soon learned Poof's location and came after him, the two fought a pitch battle and seemed equally matched, however, Poof and Timmy noticed that Foop was extremely tired due to not having a nap, claming he did not need them. Thinking quickly, Timmy summoned the Fairies and Anti-Fairies (and one Burger World Employee), who proceeded to sing a lullaby, which successfully made Foop fall asleep, causing him to fall into his Mom's arms.
Everyone then tries to figure a way to undo all of Foop's evil deeds. Timmy then figured out, that since Foop was the opposite of Poof, and bad things happen when Poof cries, that good things happen when Foop cries, Poof proceeded to swipe Foop's bottle, causing him to cry (but not before he says "You took my bubba?"), which reversed all the damage he had done and reverted everyone back to normal.
Foop was then locked away in a maximum security time-out playpen in Abracatraz, but vowed to escape and seek his revenge against Poof.
Later he did escape in the episode, "Playdate of Doom" he attempted to destroy Poof once again by fooling Cosmo and Wanda that he'd reformed. However, he planned to send Poof to an alternate dimension. He tried to make Poof look bad to Wanda so he could achieve this, but Foop was tricked by Timmy into going inside the playpen, which was actually the dimensional door, stranding Foop in the parallel universe still vowing revenge on Poof.
"It's Foop, you triangular twit! One F, two Os, one P! It's not that difficult!!" - Foop
Going to Spellementary School
After he somehow escaped his previous imprisonment in a parallel dimension, Foop went to Spellementary School and made many attempts to become the most popular kid in school. They all failed miserably, so Foop transformed the school into his own version of the school (Smellementary School). After fighting Poof, he sent Spellementary School into a black hole, but he failed a third time due to the old saying "saved by the bell", when the school day ended and everything was changed back to normal. Foop was given detention, but Poof pardoned him, upsetting the Anti-Fairy that he was saved by his nemesis "yet again". When Foop got outside, he was slammed in the face by Cosmo with a shovel as he tried to swat a sprite on Foop's face.
At his next appearance at school, Foop seemed to be forming a buddy relationship with Poof, but when a new student is brought in for the school play, a beautiful young fairy named Goldie Goldenglow, Foop's dangerous side reemerges once more, and he and Poof begin to compete for Goldie's affection! They face off against each other for the lead role in the play, and Foop manages to win it, but to his surprise the third role player that neither wanted to be was the true hero of the play and Poof got to kiss Goldie .Foop bagged the idea of winning the heart of Goldie because she kept on getting his name wrong.Poof and Goldie are later seen sharing drinks, with Foop attempting to sabotage their moment from under the table before he is attacked by his own traps.
Timmy's Secret Wish
Foop was the prosecuting attorney in Timmy's Secret Wish!, having gotten his degree while imprisoned in Abracatraz. Foop reasons that if Timmy loses his trial then that means Poof would no longer exist because all of Timmy's wishes would have to be undone, and Poof was born from one of Timmy's wishes. Foop also chose to become an attorney because he wanted to be even more evil.
Foop manages to win the case, and is ecstatic, until Jorgen points out as Poof's Anti-Fairy counterpart, Poof disappearing means Foop disappears as well. Shortly after that is said Foop disappears.
Poof and Foop are both later rescued from a place where undone wishes go (The Hocus Poconos) and brought back when Timmy proves himself to the Fairy Council that he is not selfish after they found out he made a secret wish.
Home Sweet Home?
Throughout the series his home has changed as well become a mystery.
He originally lived with his parents at Anti-Cosmo's Castle when he was born. But soon after he was sent to Abracatraz. Since his escaped his home has been a mystery. Twice it has been suggested that he lives with his parents again. One time was in Love Triangle when he mentions that his mother had packed chicken nuggets and snake venom antidote in his lunchbox. The other time was in Scary GodCouple when he mentions that he had an accident on the ride over, suggesting that one, if not both, drove him. However, Anti-Cosmo and/or Anti-Wanda has/have been seen with him, not even during the play scene in Love Triangle. There is another scene in The Terrible Twosome where Foop is seen in a castle, but this is unconfirmed if it is Anti-Cosmo's Castle.
Since he was born he has disliked Anti-Wanda stating "I am bored with you already" after their first hug. However, he seems to appreciate her because she helped him to find the nearest power source (the Anti-Big Wand). Also, in the episode Love Triangle, he appreciated that she packed snake venom antidote with chicken nuggets into his lunch. It is likely that Foop has a normal relationship with Anti-Wanda like any mother and son would have.
Foop does not like his father's authority and wishes to be left alone. Although, he has taken a few tricks from his father. He used a sling shot in the episode When Losers Attack, just like his father did in the episode Fairly Odd Baby. He also speaks with British accent like Anti-Cosmo and has inherited the same set of fangs his father has.
Foop and Poof
Upon knowing about him Foop wanted to destroy him. But after Anti-Poof and Playdate of Doom Foop warms up to Poof (but still tries to destroy him.). Eventually, after School of Crock, Foop and Poof are finally cool with each other and Foop apologizes for trying to destroy Poof.
Foop and Vicky
Foop is crazy terrified of her because she can do bodily harm to him. Vicky is so deranged she lets Fruit Bats nest in her room which makes Foop question "What are You???" In the end he stands up to Vicky (getting zapped twice by his baba in the process) and zaps her.
Foop and Timmy
Timmy first thought Foop wouldn't do much harm because he was a newborn but was later proved wrong. Foop's revenge is now redirected towards Timmy (probably because Foop can't destroy Poof without wiping himself out too).
Foop and Crocker
Crocker was amazed that a baby was evil (and pretty scary). Foop visits Crocker for help sometimes too but in School of Crock he didn't know Crocker but he did comment on how terribly mean he is.
Foop and Anti-Sparky
Foop couldn't keep watching the happiness Sparky was bringing to the Turner family, so he decided to replace Sparky with an evil creature from Anti-Fairy World pet store. There, he met Anti-Sparky and chose him. Anti-Sparky succeded in making Timmy and his parents' lives miserable but kept threatening Foop for looking at him in the eye, correcting him and raising his voice at him. Foop, fed up with the dog's attitude, attempted to blast him but Anti-Sparky reacts quickly and eats him. Cosmo kicks Anti-Sparky in the back (in an attempt of taking off the shoes he was wearing) and freed Foop, the Johnsons and the wands. Cosmo and Wanda use their magic to send Anti-Sparky back to Anti-Fairy World while Sparky (who was missing by trying to catch a ball that his Anti-counterpart threw around the world) stops Foop from annihilating Timmy and the Anti-Fairy Council punishes Foop for failing to complete his mission of replacing all the good pets for evil ones.
Foop and Chloe
Upon meeting Chloe, he tried destroying her, Timmy, Cosmo, and Wanda in The Big Fairy Share Scare. Later on in future episodes Chloe was nothing but an obstacle for Foop, until in another episode when Foop tries to break Chloe's niceness as it is corrupting his home. In Certifiable Super Sitter Foop warms up to Chloe as they hugged and Foop began to cry.
