So like you said, Gan-Q became a fairly major recurring monster in the franchise, starting with Mega Monster Battle. He notably made reappearances in Ultra Zero Fight, three episodes of Ultraman Ginga S (including the fan favourite episode Gan-Q’s Tears) and the Ultraman R/B movie.

And as the kind of guy who keeps track of that sort of thing, in the “Ultra Monsters” setting some of Ultraman Trigger’s Hyper Keys have containing the cries of the Ultra’s most iconic foes, Gan-Q is one of the few monsters to be featured in two different Keys (others being Red King, Pigmon, Gubila, Mefilas/Uringa (which are different monsters with the same cry, but are otherwise unrelated), Windam, Miclas, Agira, Nurse, King Joe, Bemstar, Gymaira, Golba, Deathdrago and everything in the Zoffy Key except Dreamgillas)
