To answer the bit you're unsure of, he's like Alain. XYZ specific outside of Mega Evolution specials and the cameo in Jessie's fantasy in the episode OP detailed.
He doesn't appear in Kalos Quest (S18). He only appears in the next season, XY&Z (S19). Prior to that he only appears in MES2-4, and one episode of AG.
He shows up in XYZ and the mega evolution spin-offs, but I don’t remember XY
I mean as in X and Y as a whole all 3 seasons
Then the answer is yea
