If Negaduck was kidnapped and imprisoned in a dungeon by someone who wanted to take over his criminal operation and Darkwing Duck rescued his villainous double by leading him into an escape route he made, how would DWD's doppelganger repay him?
Would Negaduck make a permanent truce with his heroic counterpart (as well as the hero’s families and friends) on not reeking havoc anymore....albeit for one day? …Or would the vill just try to kill his alternate universe counterpart out of anger for saving him once they both escaped from the dungeon?
