The Grandmaster

Few figures in Marvel's Silver Age carry quite the cosmic gravitas of The Grandmaster — a being of almost unfathomable age and power who burst onto the scene in The Avengers #69 in 1969, conjured into existence by the legendary Roy Thomas and Sal Buscema. Over more than five decades of publication, this enigmatic schemer has woven himself through landmark titles like Contest of Champions and Hulk, racking up three key collector issues along the way and sharing the page with titans like Captain America, Tony Stark, and Bruce Banner. His affiliations with both the Avengers and the Squadron Sinister hint at the sweeping, morally complex scale on which he operates — a player who moves heroes and villains alike as pieces on a board. With 56 years of continuous relevance and nearly 60 catalog appearances, The Grandmaster is one of Marvel's most enduring cosmic presences, and any serious collector would do well to seek him out.
