Agree or disagree the current DCU is jammed packed with too many heroes filling the same roles. From the Flash family to the Bat family there are just so many characters that none of them really get a chance to stand out. Without just a wholesale slaughter what would be the best way in your mind to take some characters off the board at least for a while?
Robin 3 - Time Drake - Tim decides to hang up the costume once and for all and goes off to college
Spoiler - Stephine Brown - She decides to follow Tims lead and retires to go to college too
Flash - All of them besides Wally West - Flash (Wally) is forced to suck all the Speed Force into himself leaving the rest powerless.
Superman - Jon Kent - De-aged back to an 11 year old kid. Conner would take on more a big brother role for him.
What would be your ideas to thin things out a little?
