- In the "Galactic Guardians" series, there's "The Fear". Egad, "The Fear". It's not the first animated rendition of Batman's backstory for anything. Especially when we see the flashbacks to pre-teen Bruce crying after his parents are killed off-screen, and then his first visit to Martha and Thomas Wayne's graves alongside the faithful Alfred.
- "The Death of Superman" is a very powerful episode. The fact that Superman died, the other heroes seriously mourn the loss of their friend, and the entire world deals with the lack of Superman all happened in a Super Friends episode is still quite the shock to first-time watchers.
- "The Krypton Syndrome", where Superman painfully realizes that if Krypton's destruction is prevented through time travel, then he would never have been sent to Earth, and the Legion of Doom will win.
Superman: When Krypton was saved, my father never sent me to Earth. So, to this world, there never was a Superman.
