Bob Diamond

Bob Diamond is a martial artist from Marvel's Bronze Age kung fu boom, a Hollywood actor and skilled fighter who became a founding member of the Sons of the Tiger alongside Abe Brown and Lin Sun, uniting through mystical amulets that granted them enhanced fighting ability when together.

Bronze Age Marvel had a knack for launching characters who quietly outlasted their moment, and Bob Diamond — debuting in Kung Fu Special #1 in 1974 under creator Malachi Ronin — is a prime example. Over a remarkable 45-year publishing span, this Marvel figure carved out a niche across titles like The Deadly Hands of Kung Fu and Fantastic Four, sharing pages with a genuinely impressive roster that includes Shang-Chi, White Tiger, and Abe Brown. With 36 catalog appearances and two collector-recognized key issues to his name, Diamond is the kind of deep-cut character that rewards the curious fan willing to dig into Marvel's rich martial-arts era. If you love the Bronze Age energy that made Deadly Hands of Kung Fu such a cult favorite, Bob Diamond is absolutely worth tracking down.
