I don't mind her. The psychic soul mate love story 'we can never be together' thing was annoying as ****. You run an empire, you can make a transgalactic booty call if you want. Loved that they got the Imperial Guard with it as I love that group, especially Gladiator.
I liked how every time something bad happened with them coming to Earth over Phoenix or whatever, she'd always have the hologram show up and Chuck would just be like "Really? You can't ever just show up and make a nude skype call or something? You always gotta be trying to murder someone I know? Why can't you ever show up and make it happy fun times???"
She was dumb as bricks sometimes though, she'd be overthrown by her sister or something AGAIN and she'd do nothing but boot them to some out of the way place until they got it together to do it again then the X-Men would show up and wreck **** until everyone surrendered.
All in all I don't care how helpful the X-Men or Avengers were at one time or another, Earth has caused so much trouble and stirred up so much **** and destroyed reality multiple times that she should have gotten together with the other empires and just blown up the solar system or something. Even just doing it on her own with the Guard making the sun go supernova would have done it.
All in all, love the empire but she's an idiot.
