Dr. Cassandra Knox

A product of the Modern Age's reinvigorated G.I. Joe universe at Devil's Due Publishing, Dr. Cassandra Knox made her entrance in 2004's G.I. Joe #36, brought to life by Brandon Jerwa, Tim Seeley, and Jason Millet. Her brief but intriguing run places her in remarkable company — sharing pages with the likes of Storm Shadow and Dashiell Faireborn, figures at the very heart of the Joe mythology. With only four catalog appearances across 2004–2005, she's a rare find for the dedicated completist, a tantalizing glimpse into a corner of the G.I. Joe world that rewards deeper digging.
