Agents of S.H.I.E.L.D.’s Ming-Na Wen (Melinda May) has confirmed that the show’s 5th season is poised to bring back the Kree in a big way.
“We have the Kree to deal with [in Season 5].
We can actually mention that and how strong they are and how blue they are.
While those bigger things likely won’t come in the form of larger MCU crossover, maybe this just means that Marvel’s launching of more TV spin-offs like Inhumans and bringing the Kree in for AoS season 5 is all part of a larger payoff.
