Back in the 80s Marvel tried to make Dazzler a real popstar, Basically during the 80s they will launch a popstar named Dazzler and they will sell her music and comics. But no Music company wants to make that happen. SO Dazzler remained in the comics.
Her Powers is to turn sound and music into laser and lightbeams, she can use her powers to fight villains but also enhance the visuals of her concerts.

Back in 2012, Marvel attempted to make a Dazzler movie with Lady Gaga as the lead but it never happened. Dua Lipa was also offered the role, because the concept of a Popstar who is a superhero can sell more than movies but also music too. Now MCU and Taylor Swift are undergoing negotiation to make Dazzler finally real.
Dazzler left X-men because she hates Rogue. Rouge use to be a supervillain and during her times as a villain, Rogue attempted to kill Dazzler 8 times.
So is Dazzler going to write songs about her X-boyfriends and enemies too.
Angel from X-men is her boyfriend, I think Dazzler movie is the best way to debut Rogue before an X-men movie. Start her as a villain like the comics.

Dazzler appeared on the Last Bryan Singer X-men movie for few seconds.
She use to date Cyclops
