Except for the horrible Strucker family, pretty much everyone on that show was gold. Emma Dumont as Polaris, Blair Redford as Thunderbird, Jamie Chung as Blink, Skyler Samuels as the Cuckoos, Grace Byers as Reeva Page, even Sean Teale as original character Eclipse. I would definitely not mind seeing most of them again, if those roles ever get a chance again. But I doubt it. None of those characters seem likely to be on the MCU shortlist, which will probably pull from O5 and All-New, All-Different era X-Men, with a splash of Kitty, Jubilee, etc.
