Crota

Crota, Son of Oryx, Heir to the Osmium Throne is a great Hive king and the final boss of the raid Crota's End. He is the son of Oryx and resides in Crota's Netherworld.

Biography
Crota wielded the Sword of Crota, which he used to kill a large number of Guardians and drive humanity away from the Moon. At some point afterwards, Crota fell into a deep sleep.

Eris Morn and a fireteam of five other Guardians once made a failed attempt on his life, and she was the only one to survive. With all that she learned, she helped another fireteam raid his lair underneath the Hellmouth and kill him.

After Crota's death, his father, Oryx, traveled to the solar system in order to exact revenge on the Guardians.

Gameplay
Crota shoots an Arc Fist of Darkness in his left hand, similar to the Darkness Blast used by Wizards, while using a cleaver with his right. If a member of a fireteam dies, he summons his Oversoul, which will kill everyone in the fireteam if it is not destroyed quickly enough.
