Professor Sycamore features in "Pokémon: Mega Evolution Special II" within Alain's memories and communications. He acts as Alain's mentor and employer at his Kalos research laboratory, dedicated to studying Mega Evolution. Sycamore authorized Alain's departure from the lab to conduct extensive field research on Mega Stones, establishing a professional dynamic where Alain periodically reported his findings.
During one such update from Hoenn, Alain informed Sycamore via video call about his Charmander evolving into Charmeleon. Sycamore received this news, though Alain noted he had not discovered any new Mega Stones yet. This exchange underscores Sycamore's continued role as Alain's guide and point of accountability.
Furthermore, Sycamore's lab served as the origin for Alain's quest. It was there, during Sycamore-authorized investigations in ruins, that Alain first met Lysandre. This encounter ultimately led to Lysandre recruiting Alain to collect data on Mega Evolution battles, a subsequent arrangement in which Sycamore played no part.
