Temmin Wexley is a human male from Akiva, son of the New Republic pilot Norra Wexley, and — decades later — a Resistance pilot flying under the callsign Snap. Chuck Wendig introduced him in Aftermath (Del Rey, 2015), and Greg Grunberg plays him in The Force Awakens, released three months afterwards.
The Aftermath version is a teenager running a black-market parts business out of an occupied city with a repurposed battle droid for a bodyguard, furious with a mother who left to fight a war. When Norra returns to Akiva and assembles a team — Temmin, the droid Mister Bones, the Zabrak bounty hunter Jas Emari, an ex-Imperial loyalty officer and the New Republic commando Jom Barell — he is the reason the uprising has any local traction at all.
That team hunts Imperial war criminals across the trilogy and eventually supports Han Solo’s effort to free the Wookiees of Kashyyyk. It is the clearest demonstration of what the post-2014 publishing programme was for: taking a background pilot from a film and giving him thirty years of prior life in books that reached shelves before the film opened.
Snap dies at the Battle of Exegol in The Rise of Skywalker (2019). Readers who came through the novels felt that considerably more than viewers who did not — which is either the strength of a transmedia franchise or its central design flaw, and this site takes no position.
