Haggar

Honerva, formally the Galran Empress and the witch Haggar, is a powerful witch, and loyal to King Zarkon. She is responsible for the creation of many of Voltron's Robeast opponents. In Voltron: Legendary Defender, she was an Altean user of dark magic and the former high priestess of the Druids serving the Galra Empire. She acted as an advisor to Zarkon and later recalled her memories as his former wife. She helped save him and keep him alive with her magic, yet Zarkon was still killed by his son Lotor, who hated Haggar almost as much as Zarkon. Following the loss of her son at the hands of Voltron, Haggar, now reverted back to Honerva, withdrew from the Galra Empire, taking the Alteans from the colony formed by Lotor and training them to hate both Voltron and the Galra. She had them Pilot her Komar Mechs and sent one to Earth.
