Coran (Voltron: Legendary Defender)

Coran (full name Coran Hieronymus Wimbleton Smythe) is Princess Allura's advisor, and currently the only known male Altean alive. This excludes King Alfor, who "survived" the genocide of Altea by having his memories stored in a device that would allow Allura to interact with him. However, she manually destroyed this device when the Galra crystal infected his memories.
