The final episode of Batman: The Animated Series airs, concluding the original series before it evolves into The New Batman Adventures.
The theatrical film Batman: Mask of the Phantasm is released, based on the animated series and featuring the same creative team and voice actors.
Season 1 was one of my favorite anime binges in a long time. Such a fun mix of thoughtfulness (movement through time), silliness, and cool scenes (The Ruins of The King's Tomb). I can't wait to watch season 2. I know it's airing as I write this, but I like taking in entire seasons at once if I can manage it.
