Dark Matter: Complete Story and Character Guide
Six people, no memories, one ship — three seasons toward a fourth that died on contracts.
Dark Matter ran three seasons on Syfy (39 episodes, 2015–2017), created by showrunners Joseph Mallozzi and Paul Mullie from their Dark Horse comic, produced by Prodigy Pictures. Six people wake on the starship Raza with wiped memories. According to The Hollywood Reporter, Deadline and Variety, Syfy cancelled it on September 1, 2017 — a week after the Season 3 finale. Mallozzi's blog post: "You all deserved better."
What followed was the most credible rescue attempt in this site's library: per The Verge, MGM wanted Season 4 on Stargate Command — Mallozzi executive-produced SG-1, Atlantis and Universe — as a 6–8 episode miniseries, even floating a Stargate crossover through the blink drive. Sets and cast contracts expired first. Killjoys got the double renewal that same window; Dark Matter got the epitaph, reportedly on low ratings per Dark Horizons via Deadline.
Full Season Recaps
Season 1 — Who Are We (2015)
One through Six wake on the Raza: Two (Melissa O'Neil) takes command, Three (Anthony Lemke) plays mercenary, Four (Alex Mallari Jr.) hides royalty, Five (Jodelle Ferland) hides genius, Six (Roger Cross) hides a conscience, plus the Android (Zoie Palmer) learning personhood. Corporate wars (Ferrous, Mikkei) and the crew's criminal pasts braid toward the EOS-7 station's destruction.
Season 2 — The War (2016)
The crew picks sides in corporate war while pasts detonate: Four's Ishida claim, Six's betrayal and return, the Android's humanity deepening. Ends with the Raza crew fractured and the universe darker.
Season 3 — The Invasion (2017)
The Dwarf Star conspiracy, Ryo's emperor turn, and the blink-drive endgame: reality-bending tech that could rewrite the war. The finale leaves the crew mid-fight — written as a hinge, aired as a farewell.
Character Guide
Two — The Captain
O'Neil anchors the show: engineered assassin choosing commander, the arc the finale was building toward.
Three & Four — The Blades
Lemke's mercenary-with-a-heart and Mallari's exiled prince carry the action and the honour plots respectively.
Five & the Android — The Souls
Ferland's stowaway genius and Palmer's Android are the show's conscience and its becoming-person duet.
Six — The Conscience
Cross plays the undercover cop whose betrayal and penance span the whole run; Marc Bendavid recurs as Jace Corso.
Ending Explained
Season 3 ends mid-war: the blink drive in play, Ryo ascendant, the Raza crew committed but outgunned. Mallozzi's planned MGM miniseries would have "wrapped the series and given fans the closure Syfy denied," per The Verge — 6–8 episodes, possibly through a Stargate door. Contracts lapsed; the door closed. Of every cliffhanger on this site, this one came closest to rescue.

☕ Support UsWhy Was Dark Matter Cancelled?
Syfy cancelled Dark Matter on September 1, 2017 after three seasons and 39 episodes, per all three trades. Mallozzi announced it himself; Syfy declined comment. Low ratings per Deadline via Dark Horizons; sister show Killjoys' simultaneous double renewal sharpened the sting. Canadian co-production economics (Space channel, Prodigy) left no cushion.
