Originally known only as a "spear" (槍, yari), it posses a double-helical shaft and a defined spearhead implanted with a green gem and it is first seen at the lunar Tabgha Base in a shroud. During Near Third Impact, it is used by Evangelion Mark.06 to terminate the event and Unit-01's evolution into an energy being.
The Spear is colored red in Evangelion 2.0/2.22 and promotional materials for the film; however, in a promotional illustration for Evangelion 3.0, along with an Unit-06 action figure, it is colored black or dark gray instead.The reason for this discrepancy is currently unknown.
In Evangelion: 3.0 Kaworu and Shinji head down into terminal dogma to retrieve the Spear of Cassius along with the Spear of Longinus from Lilith's corpse. Kaworu implied that both spears in concert could rebuild the world. However, what they found were two Spears of Longinus and no Cassius.
