Question: do any of the cheers characters appeared on frasier?
Answer: Although all living major characters of Cheers had an appearance in Frasier (except Kristie Alley), the only one that appears in more than one episode is Frasier's ex-wife Lilith. Norm, Paul, Phil, Walt, Carla, and Cliff all appear in the season nine episode "Cheerful Goodbyes".
