The longer a character is used, especially when numerous creators are involved, the more likely it is that something will be added to their backstory that contradicts something else or comes across as pointless or convoluted. Provided are five examples of such presented throughout the history of the X-Men.
BANSHEE
Originally
Irish mutant Sean Cassidy was captured by the mutant group Factor Three and fitted with a headpiece that would explode if he disobeyed them. Placed under the care of the Ogre, Banshee became a small time crook until he went up against and was defeated by the X-Men, who freed him of his captivity. He became an ally until eventually joining the team.
It Eventually Became
Sean Cassidy worked as an Irish agent of Interpol for years. While on a mission, his beloved wife Maeve was killed and he left Interpol to travel the world. Eventually he settled in New York, joining the NYPD, but did not stay in the force for a lengthy time. After this period, he was captured by Factor Three.
What happened?
Wanting Banshee to serve as a more veteran presence on the “all-new” X-Men, it was written in a quick line that he had been an ‘ex-cop’. The NYPD part was added when he was seen wearing an NYPD shirt while on a picnic with Moira MacTaggert and the X-Men. The Interpol part was likely added in to keep the cop part going while playing up Banshee’s international heritage.
Why it Doesn’t Work
The Interpol/NYPD parts of Banshee’s origins overlook one of the main points of the character’s first appearance. While under the watch of Factor Three, Banshee willingly took the part of the petty crook, happily stealing fine tobacco and paintings for his own personal gain. Even his handler the Ogre chastised him for doing such crimes as it brought unwanted attention to their activities. Even when recruited to the X-Men, Banshee commented that it would be nice to “tread the straight and narrow” meaning to turn away from his former life of crime. By the time he had been established within Chris Claremont and John Byrne’s run on X-Men, this was all but forgotten, save for a single image on a Cyclops-narrated history of the X-Men.
