Both Star Trek: Lower Decks and Star Trek: Prodigy are both viable options for him given that they’re both animated, or Star Trek: Picard or any other series could just write a role that he deems worthy enough to hop in the makeup chair for.
If there’s any upside to Michael Dorn’s recent comments about appearing in Star Trek, it’s that there are two shows he could reprise his role as Worf in wearing absolutely zero makeup.
I’m eager for whatever solution that can be worked up soon because I’ve been jonesing to see Worf acting grumpy on a starship lately.
