King Shark

King Shark, whose true name is Nanaue, is one of DC's most savage and unpredictable anti-heroes — a hulking, humanoid great white shark with a taste for destruction and, occasionally, his own teammates. Believed to be the son of a shark god of Hawaiian legend, Nanaue possesses a terrifying combination of raw physical power, near-invulnerability, and an instinct for violence that makes him as dangerous to his allies as to his enemies. His first appearance in Superboy #0 (1994) marked the debut of a character who would grow far beyond his origins as a simple aquatic bruiser, eventually becoming one of the most beloved and collectible figures in DC's roster of antiheroes.

Nanaue's early appearances pitted him against a young Superboy in the pages of the '90s ongoing series, establishing him as a genuine physical threat capable of going toe-to-toe with a Kryptonian powerhouse. His brutal strength, rapid healing factor, and animalistic ferocity set him apart from the typical DC villain, and readers quickly gravitated toward his unpredictable nature. His membership in the Secret Six — Gail Simone's critically acclaimed team book — is considered a career-defining run, showcasing a surprisingly layered and darkly comedic side to the character that elevated him from B-list monster to fan favorite.

King Shark's tenure with the Suicide Squad is where his collectibility truly exploded. His presence across multiple volumes of Suicide Squad, combined with widespread pop culture exposure through video games and television, sent back-issue demand surging for his key appearances. Collectors hunting his earliest issues — particularly Superboy #0 and his formative Superboy appearances — have found those books appreciating steadily as the character's cultural footprint has grown. His Secret Six issues under Simone are equally sought after, representing some of the best character work the villain has ever received.

For collectors, King Shark represents the kind of character whose books reward early hunters. His first appearance in Superboy #0 is an essential key issue, and the full run of the 2005 Secret Six miniseries and subsequent ongoing are must-haves for anyone building a serious DC collection. Suicide Squad appearances across multiple eras add depth and variety to any Nanaue-focused run, and his Legion of Doom ties connect him to some of DC's biggest event storylines. With a devoted fanbase, a growing media presence, and a charisma that leaps off the page — usually right before he bites someone — King Shark's back issues are as ferocious a collectible as the character himself.
