Cassie Sandsmark

Few characters have made a debut as memorable as Cassie Sandsmark, who burst onto the scene in Wonder Woman #119 in 1997, the creation of writer-artist John Byrne. Born in the Modern Age of DC Comics, she's gone on to rack up 126 catalog appearances across nearly three decades — a testament to how deeply she resonated with readers from the very start. Her world is populated by some of DC's most beloved young heroes, sharing adventures with the likes of Robin, Superboy, and Wonder Woman herself, and she's most at home in the pages of Teen Titans, Young Justice, and Tiny Titans. With six key-issue appearances to her name, Cassie is the kind of character collectors circle and newcomers quickly fall for — a genuine cornerstone of DC's younger generation.
