* FanNickname: Some fans prefer to call Matt as [="BatMatt"=] since the release of New Power saga.
* PlayingAgainstType:
** Creator/SteveBlum as Blunk.
** Creator/DeeBradleyBaker as Cedric.
* ScrewedByTheNetwork: The ''creators'' of the series got screwed out of it halfway through the first arc! Disney Italia dismissed them, and thus the rest of the story went in a different direction then what was intended. If one reads Issue 7, this change becomes obvious (Elyon suddenly pulls a HeelFaceTurn and is revealed as "The Light of Meridian", she and Cornelia are suddenly said to be best friends, Caleb is introduced out of nowhere as Cornelia's literal dream man, Phobos comes out of the shadows sooner than one would expect, the general story changes it's focus to the Crown of Light, etc, etc.)
-->'''Alessandro Barbucci & Barbara Canepa:''' "We conceived of "W.I.T.C.H." together with Elisabetta Gnone, the then director of girls publications for Disney. We worked for three years in secret on it and she then presented the project to the big bosses at Disney. They thought that this project was crazy, a sure-fire bomb, complete waste of time, and that mangas wouldn't have a chance in Europe anyway (!!!). However, we didn't let ourselves be led astray and worked for another year on it anyway, with a tiny budget and without publicity. And then the series became a worldwide hit. The official version from Disney is, of course, that "W.I.T.C.H." is a product of their brilliant, visionary marketing strategy...the end of the series was then taken out of our hands, we actually had something a lot more intelligent planned for it. Now, as you can see, Elisabetta Gnone and the two of us no longer work for Disney...a really sad story."
** Meanwhile, low ratings foiled Greg Weisman's plans for a third season of the cartoon- as per usual for him.
* WhatCouldHaveBeen: Peter, Nigel, Eric, Martin and Alchemy were intended to play a larger role in the cartoon's cancelled third season.
** Back when the comic book was been created, there had been an attempt to put ''Daisy Duck'' among the characters.
** Also when the comic was being created, the original title was supposed to be [[FunWithAcronyms M.A.G.I.C.]] (later recycled [[WhoWouldWantToWatchUs when Will wrote a musical based on the fight against Phobos]] and [[ContrivedCoincidence the chosen actresses just happened to have names with those initials]]) and Cornelia (then called Maria) should have been the leader as the oldest.
** When Disney acquired Marvel in 2009, there was an attempt to merge ''W.I.T.C.H.'' into the mainstream Marvel universe, with that attempt and a 2013 attempt failing due the sheer difficulty of merging the ''W.I.T.C.H.'' universe into the Marvel continuity. Planned plot points and storylines included:
*** The Guardians would have teamed up with Franchise/SpiderMan to fight the Sinister Six, Venom, Carnage, the Kingpin and Green Goblin. Spidey would have been a big brother of sorts, teaching them to responsibly use their powers.
*** Other team-ups would have been with the ComicBook/FantasticFour (against SelfDemonstrating/DoctorDoom), the Franchise/XMen (who would have already met C.H.Y.K.N.) against SelfDemonstrating/{{Magneto}} (the enemy fought by C.H.Y.K.N.), Mr. Sinister, the Hellfire Club, the Sentinels and Apocalypse, ComicBook/DoctorStrange against Dormammu and Mordo, and the Avengers against Doom, Loki and Red Skull.
*** ComicBook/{{Galactus}} would have made an attempt to devour Kandrakar, with C.H.Y.K.N. ultimately driving him off. Galactus was described as one of the few Marvel villains (alongside the Red Skull, Dr. Doom, Apocalypse, Thanos and Dormammu) worthy of fighting either known incarnation of the Guardians.
*** Magneto would have felt responsible for Nerissa's fall, as it had been the introduction to his own extremist ideals that ended up fueling her ambitions.
*** Doormouse and ''Ben Parker'' would have been temporarily resurrected to help the Guardians and Spider-Man recovering after a difficult battle.
*** Thomas Vandom would have returned and been revealed as a cousin of [[Franchise/SpiderMan Norman Osborn]].
*** Phobos would have managed to will himself back to life and, once back to Earth, allied himself with Doom, Magneto, the Sinister Six, Red Skull and Hydra (secretly from the others) and Loki, and brought Nerissa back to life. Things would have turned sour when [[EnemyCivilWar Doom, Loki, Red Skull and Phobos tried to become the sole leader]] and Magneto and Nerissa, [[EvenEvilHasStandards who already felt their known allies were too imposing and greedy for power]], finds out of the Red Skull (Magneto's issues with Red Skull are already well known, and [[EvenEvilHasStandards Nerissa despises Nazis]]).
** There were two planned spin-offs in 2012, one concurrent to the main series and the other being a prequel starring C.H.Y.K.N. fighting an unknown enemy (that would play a role in Nerissa's corruption and fall). Both projects were shelved with the second attempt at a Marvel cross-over.
* TheWikiRule: [[http://witch.wikia.com/wiki/W.I.T.C.H.ipedia Here]] is the wikia for the comic/cartoon.
* WordOfGay: GregWeisman (Supervising Producer and Story Editor of the second season) [[http://s8.org/gargoyles/askgreg/search.php?qid=8857 believes Irma is a lesbian]], and that Nerissa is bisexual... once being lovers with Cassidy: "You have no idea what she meant to me."
* WordOfGod: Because Will controls Quintessence, she is the most powerful of W.I.T.C.H. and one of the most powerful beings in the universe.
** ...which is ironic considering she didn't have any offensive powers whatsoever in the first season.
