The Marvel Cinematic Universe has fully embraced long-form storytelling with its new Disney+ series, including WandaVision, Secret Invasion, and Loki. However, these streaming series are far from the franchise's first foray into the world of television. Years ago, Marvel Studios' most inventive television storylines came in the form of series like Agent Carter.

Following the exploits of Hayley Atwell's Peggy Carter after the events of Captain America: The First Avenger, ABC's Agent Carter ran for two seasons before being abruptly canceled. Nevertheless, the series still managed to deliver some truly terrific television episodes in its short time on the air.

10 Now Is Not The End

Season 1, Episode 1

Agent Carter's pilot episode, "Now is Not the End" kicked off one of the MCU's best non-Disney+ series by reintroducing Hayley Atwell's eponymous character after the end of World War II and the events of Captain America: The First Avenger. Now working for the Strategic Scientific Reserve, Peggy Carter looks for new meaning in life while struggling with the rampant misogyny she faces in the office.

The pilot episode gives audiences a fresh perspective on Peggy Carter's life after the war, including how she coped with the loss of Steve Rogers, a.k.a. Captain America. It also introduces audiences to the lovable cast of the series, including Enver Gjokaj's Daniel Sousa, Chad Michael Murray's Jack Thompson, and James D'arcy's Edwin Jarvis.

9 Hollywood Ending

Season 2, Episode 10

The final episode of Agent Carter's second season also acts as the series finale. Entitled "Hollywood Ending," the finale depicts the final battle between Peggy Carter and Whitney Frost, who wields a terrifying amount of Zero Matter. Carter and her allies eventually emerge victorious, but only barely.

After a satisfying conclusion to the ongoing conflict with Frost, Agent Carter's final episode finally gives viewers what they had been waiting for: the beginning of Peggy and Daniel Sousa's romantic relationship. However, Agent Carter also ends on a massive cliffhanger, as Agent Jack Thompson is gunned down in his hotel room by an unseen assailant.

8 A Little Song And Dance

Season 2, Episode 9

Agent Carter's penultimate episode, "A Little Song and Dance," features the villainous Whitney Frost as she attempts to absorb the remaining Zero Matter, which will only grow her incredible set of powers.

"A Little Song and Dance" includes some of the most dramatic storytelling in the entire series, showcasing just how exciting Agent Carter could have become had it been renewed for future seasons. The episode also ends on a massive cliffhanger, as massive amounts of Zero Matter are unleashed into the world.

This episode has some fun with the dynamics between its characters and Dottie Underwood, who constantly keeps audiences guessing as to her true allegiance.

Agent Carter's second season premiere ups the ante, as the series tackles a much bigger storyline and a much more exciting villain than in its first season.

All seems lost for Peggy Carter's team in "Monsters," the seventh episode in Agent Carter's second season. The episode features the fallout of Whitney Frost's big power grab at the end of the previous episode as she begins to grow into one of Peggy Carter's most lethal villains in the MCU.

As dire as the situation for Carter's team may be in "Monsters," it is nevertheless endlessly entertaining for viewers to watch Whitney Frost's rise to power. After killing the Council of Nine and establishing herself as the season's true villain, Frost becomes one of the most entertaining antagonists in the entire series.

Action is heavy and emotions are high in Agent Carter's first season finale.
