10 Best 100th Episodes Of TV Shows Ever
9. Arrow - Invasion
Like Batman and Smallville before it, Arrow became the latest DC Comics show to reach three figures in its fifth season, and it celebrated in style.
The episode, Invasion, was part of that year's epic Arrowverse crossover, which this time was dealing with an alien invasion. For Arrow's instalment, it really decided to go heavy on homaging the past while doing everything the show had become known for.
Key players from throughout the show's run returned, including Laurel Lance and Oliver's parents, helping to give the hour a strong emotional core, and that was accompanied by a great action set-piece and some incredible Easter eggs.
