The Tatsunoko vs. Capcom: Ultimate All-Stars guide for Gold Lightan has received heavy revisions courtesy of Nyoronoru.The difference between Gold Lightan and PTX-40A Giant-wise is that Lightan is more of a poking, combo-centric character with a lot of far-reaching normals, where as PTX relies more on his special moves to achieve victory.
Lightan also relies more on creating openings in defense with pressure where as PTX relies more on mixups and juggles to deal damage. When faced together in battle, Lightan has a slight advantage because most of PTX's moves are ground-centric, where Lightan excels.
