10 Best Superman: The Animated Series Episodes
6. "Speed Demons"
The Flash is always saying he's "The Fastest Man Alive" and the comics have entertained readers with a few issues putting this claim to the test. Who better to race the Flash than Superman, the guy who can fly circles around the planet faster than the speed of light?
"Speed Demons" is the fourth episode of the second season and is often considered a fan-favorite thanks to the race to determine who is truly the fastest man alive. Unfortunately, this is the DCAU so there can't be a race without a supervillain mucking things up a bit.
While the race was established as a charity event, it was just a hoax to push the two speedsters into generating enough energy for the Weather Wizard's evil ploy. His plan was to use their energy to power his machines and change the weather anywhere on the planet, but the two superheroes band together to defeat his evil plot.
This episode was a lot of fun to watch thanks to the friendly rivalry between the Flash and Superman. After defeating the Flash's nemesis, things wrap up rather nicely, but the two heroes couldn't finish the day without completing their race so the episode closed with them continuing to see who was the fastest. Unfortunately, that question was left unanswered, leaving the audience to continue guessing just who really is the Fastest Man Alive...
