What If? Planet Hulk #1 (2007) Leonard Kirk is an American-born comic book artist based in Canada whose versatile penciling work has made him a reliable presence across both major publishers for more than three decades. Active in the industry since 1991, Kirk has built an impressive body of work spanning superhero titles at both DC and Marvel, with credits as artist, inker, and occasional writer across nearly 400 issues through 2024.
Star Trek: Deep Space Nine #[3] (1995) Among his most prominent assignments are extended runs on Supergirl and JSA at DC Comics, where he demonstrated a knack for ensemble casts and character-driven storytelling. His Marvel work includes notable stints on Captain Britain and MI13, Fantastic Four, All-New Wolverine, and Squadron Supreme, showcasing a clean, expressive style well-suited to both action sequences and quieter character moments. Beyond the Big Two, Kirk has also lent his talents to licensed properties including Star Trek and Witchblade.
