Many loose ends and cliffhangers from Marvel Television's Defenders projects can now be resolved in the MCU as Marvel Studios has hinted at the Defenders Saga officially being canon. While Marvel Television shows such as Agents of SHIELD, Agent Carter and Runaways appealed to a family-oriented audience, the Defenders Saga, which aired across six series between 2015 and 2019, told more grounded and mature stories. The Defenders Saga's shows were canceled in 2018 and 2019 ahead of Marvel Studios developing its own TV shows for Disney+, but the six Netflix series may now be a crucial part of the MCU.
