Marvel fans will know that Kasius is the main villain in “Agents of S.H.I.E.L.D.” Season 5, where he was played by Dominic Rains. In the series, the team goes up against the leader of the Kree Watch because he forces the last remnants of humanity to live in squalor, as slaves for the aliens — and he constantly berates them by saying they’re lucky to still be alive. He’s drunk on power, and has bigger aspirations in the Kree Empire, so wants to leave the Lighthouse.
Even though Rains is only in eight episodes of Season 5, he easily cements himself as one of the most interesting villains of the series. However, as good as Rains is in this Marvel role, the part for which many TV viewers most recognize him from is that of the charismatic Dr. Crockett Marcel in “Chicago Med.”
The star joined “Chicago Med” back in 2019 for Season 5, and he has been a huge part of the series ever since, having starred in over 40 episodes so far (via IMDb). The Chief Surgical Resident is a bit rebellious when it comes to carrying out certain procedures, largely because he has faith in his own abilities — as well as being slightly egotistical, to say the least. Crockett also has some pretty rough edges when it comes to his love life — he even kisses Pamela Blake (Sarah Rafferty) in Season 7, even though he’s dating her daughter, Avery Quinn (Johanna Brady), a scene that many viewers felt went too far. In regard to that plot point, executive producer Diane Frolovhas told TV Line, “I think it’s pretty clear that Crockett is attracted to Blake and also to her daughter.” Well, that’s awkward — but at least they’re not trapped in space!
