!!The first series contains examples of:
* MisBlamed - There was no PanderingToTheBase to bring Jean back. Nor was it ExecutiveMeddling. It was simply that they finally figured out a way she could return ''without having killed five billion people''.
** In fact it was executive meddling that kept her from returning until they found a way (Madelyne Pryor was even supposed to be Jean reincarnated until that was nixed).
!!The second series contains examples of:
* MyRealDaddy: PeterDavid is the man behind both the second and third series, and the title's name is now always linked to him.
* RescuedFromTheScrappyHeap - Madrox, who annoyed writers and artists alike for starting life as a visually boring and bland character whose superpower was to create visually boring copies of himself. It took PeterDavid's addition of creatively using his powers, a sense of humor and a philosophical side for the character to take off, and even after that, most writers ''still'' don't know what to do with him.
!!The third series contains examples of:
* NightmareFuel: Jamie Madrox [[spoiler: absorbing his own son.]]
** Also the mutant internment camps of the future.
** [[spoiler: The birth of Rahne's son.]] Just..... [[spoiler: Rahne's son]].
* DieForOurShip: Some fans of Rictor/Shatterstar REALLY hate Rahne, especially after she tells Rictor he's the father of her baby.
** She never specifically stated he was the father, he just assumed. Mind you, she ''encouraged'' that assumption because she had religious problems with his relationship with Shatterstar and was trying to CureYourGays.
* GodModeSue /MaryTzu: Layla, especially at the beginning. She knows everything everyone is going to do, outwits every enemy, pulls multiple gambits and eventually [[spoiler: it turns out it was all thanks to [[TransferableMemory memory uploading]] by her future self and her REAL power is ressurrection]]. While much of it can be explained by her knowledge of the future allowing her to prepare for a given situation, sometimes it seems the world simply works in her favor, most egregious example is satellite just happening to fall at the fence of the prison she was held in, allowing her to escape. [[JerkSue Her dickish attitude]] doesn't help.
* MyRealDaddy: Layla Miller was introduced in ''HouseOfM'' by Creator/BrianMichaelBendis as a living DeusExMachina, but her more well-known "I'm Layla Miller. I know stuff."-persona & subsequent CharacterDevelopment was the work of Peter David here.
* RescuedFromTheScrappyHeap: Layla again. She was previously regarded as nothing but a human DeusExMachina for ''HouseOfM'', but ''X-Factor'' has turned her into a genuine, interesting character.
** Shatterstar as well.
* RonTheDeathEater: Rahne seems to be the most common target of this. She's either a kind-hearted woman with some [[BreakTheCutie very serious]] [[TheWoobie emotional issues]], or an [[BitchInSheepsClothing evil manipulative]] she-bitch out to ruin everything.
