Joker will take Zombozo's place in the episode, The Last Laugh.
- Due to the story being an amalgam of both the Ben 10 and DC universe, there's a chance that the heroes will have a run-in with the Joker, who is gassing young children, which would cause Ben and Robin to run into Batman, who is trying to capture the clown prince of crime.
More members of the Teen Titans will show up.
- Considering that we already meet Robin and Starfire at the beginning, the rest of the Titans will show up as well. Raven may show up to help the heroes stop Hex and Charmcaster from getting the charms of Bezel.
