Since versions of the "DC Showcase: Green Arrow" and "Catwoman: Hunted" films are confirmed to have happened on Earth-16, does that also mean that the characters who have not yet appeared on Earth-16 (such Catwoman, Merlyn, Cheetah, Julia Pennyworth, etc.) also exist ? Also, in your headcanon, when exactly in the Earth-16 timeline did those versions of the events of the two films took place?
1. Versions of them, yes.
2. For the Green Arrow Showcase, check out Young Justice: Targets to get the timing. For Catwoman: Hunted, no spoilers.
