Thomas Kalmaku
Thomas Kalmaku is an Inuit aircraft mechanic who became the trusted best friend and confidant of Green Lantern Hal Jordan, serving as one of the few civilians who knew Jordan's secret identity and chronicling his adventures in a private journal.
A loyal fixture of the Green Lantern universe since his Silver Age debut in 1966, Thomas Kalmaku was brought to life by the legendary team of Gardner Fox and Gil Kane β two architects of DC's most imaginative era. Over nearly six decades, he's kept remarkable company, sharing pages with Hal Jordan, Carol Ferris, Arisia, and Kilowog across titles like Green Lantern, The Green Lantern Corps, and The New Guardians. With three key-issue appearances to his name and a publishing history stretching all the way to 2025, Thomas is one of those enduring supporting presences who quietly anchors a corner of the DC universe β the kind of character a true collector learns to appreciate the longer they dig into the mythos.
