Olkari Cubes were introduced by Coran in season 2 of Voltron: Legendary Defender in the episode Greening the Cube as floating cubes from Olkarion, echoing everything one says to the cube. In the episode, Commander Branko forces the Olkari with their capability to create powerful devices out of blocks of steel to create one gigantic cube as a superweapon to destroy Voltron.

Later in season 2, in the episode Stayin' Alive, Olkari Cubes are also used as a communication device between Allura and Coran, as well as between Slav and Coran. The depiction of the Olkari Cubes in season 2 is the premise of the game «Voltron: Cubes of Olkarion». In the game’s story, emperor Zarkon forces the Olkari not to create just one single cube, but various cubes with versatile capabilities to destroy the Voltron coalition.

In the series, the Olkari Cubes reappear in Season 8 in the episodes Battle Scars und Genesis where Honerva steals cubes from Olkarion to power a dimensional rift.
