Sean Cassidy

Sean Cassidy has been a fixture of the X-Men universe as presented by Panini Deutschland, debuting in their X-Men #1 in 1997 and maintaining a presence in the catalog stretching across nearly three decades into 2026. Appearing most frequently across X-Men, Die furchtlosen X-Men, and X-Men Special, this is clearly a character shaped by the German-language comics market, keeping remarkable company alongside icons like Wolverine, Cyclops, and Beast. With 2 collector-significant key issues among his 18 catalog appearances, Sean Cassidy is a rewarding find for fans who love digging into the international side of X-Men publishing history.
