I remember the white suit he had when he took over for the Wizard and Jr. had to step up as the new Captain Marvel, but then the whole Cry for Justice storyline happened and then the reboot.
Wasn't there a special issue between Final Crisis and Flashpoint where the wizard supposedly returned, depowered Mary and Billy before setting out to take down Freddy. I remember reading it and then the story vanishing unresolved with the New 52 reboot.
