Arrow: You could introduce a new hero. Doctor Mid-Nite, Geo-Force, or Black Lightning. And you could have the villain be one of those hero's enemies.

Flash: An episode focusing on Impulse, with flashbacks showing his backstory. The villain could be someone from the future, like Abra Kadabra or Chronos.
