Revamped, Killed Off, or Limbo

Which comic book characters do you believe need some major changes.

Rogue (killed off or revamped into someone less whiny)
Wally West ( needs to come back . Barry not interesting)
Mikaboshi (makes a good foil for loki in his first incarnation )
Xavier (Should have just died from Bishops bullet to the dome)

Mikaboshi needs to stay dead/trapped after the fail that was Chaos War

Both Mikaboshi and Sentry must stay dead.

Cyclops needs to be what he was pre-Fraction. Definitely.
Colossus needs to be non-Juggernaut.
Green Arrow needs a major overhaul.
