Knights of Sidonia (Seasons 1–2)

Knights of Sidonia (2014) is a Japanese science-fiction anime you can watch online on iFILM. Polygon Pictures built it in full CG from Tsutomu Nihei's manga, with Kobun Shizuno directing.

Earth is gone, wiped out by the Gauna — massive alien creatures that are almost impossible to kill. What's left of humanity has spent a thousand years fleeing through the void aboard a hollowed-out seed ship called Sidonia. A young man named Nagate Tanikaze spent his whole life hidden in the lower decks, living on synthetic rice and flying mechs only inside an old simulator. When he's finally dragged to the surface, the Gauna reappear, and the rookie is strapped into a real Garde unit.

The show blends grim deep-space survival with surprisingly grounded school-life drama: cloned pilots, a crewmate who survives by photosynthesis, and a love triangle in the middle of an extinction war. The creature design is its own draw — eerie, biological, nothing like the usual anime monster. Stream every episode of Knights of Sidonia online on iFILM.
