While she has interacted with the X-Men and even joined them on a mission in the comics, she is primarily a member of the Avengers and other superhero teams.
Here's why:
* Powers: While Ms. Marvel's powers are related to shape-shifting and superhuman strength, they are not a result of the X-Gene mutation that defines the X-Men.
* Origin: Kamala gained her powers through a strange mist, not through a genetic mutation.
* Affiliation: Her primary superhero affiliation is with the Avengers. She has also been a member of the Champions and the Young Avengers.
So, while Ms. Marvel has worked with the X-Men on occasion, she isn't a permanent member of their team.
