Cayde-6 was the Hunter Vanguard in the Tower. Cayde-6 sold a variety of Hunter armor (including Vanguard armor) and emblems. All Guardians could purchase and own these items regardless of their class, but only Hunters can equip Hunter armor.
During the initial attempt by Guardians to retake the Moon from the Hive, Cayde-6 ended up in a most peculiar situation. Falling back from overwhelming Hive forces, he took cover behind a crashed jumpship, only to discover that a Fallen Baroness was there as well. As they both had a common enemy, the two opted not to kill each other, and continued to fight the Hive. After most of the Hive were killed, Cayde returned to the crashed ship, only to find the Baroness mortally wounded. In the end, he was forced to kill her.
After the death of his friend Andal Brask at the hands of Taniks, the Scarred, Cayde took on the Vanguard Dare. To his regret, he lost the bet, and was forced to accept the challenge of becoming the new Hunter Vanguard.
During some of Cayde's travels, he hid away stashes of information, clues to the past, and leads on rare and exotic weapons. One of the items he had hid away was a preserved 1883 copy of Treasure Island. The book was hidden in the Speaker's personal library and has drawings and notes from Cayde within the book.
Despite his diligence to his work, he longs for the opportunity to get back into combat. After speaking with Cayde-6, he will sometimes whisper, "Hey, take me with you," or, "I need to get back in the field." further reinforcing this idea. He also is a gambler, placing bets on the outcome of several events.

- "Need destruction at a distance? Nightstalkers are gonna need support against heavy armor while Bladedancers want it up close and personal. Find a Gunslinger. They'll know what to do."
- "A Hunter back from a quest? Now that's the best storyteller in the galaxy."
- "Sure, it was cold. But I'm an Exo. We keep going."
- "The Vanguard was the best bet I ever lost."
- Cayde-6 is voiced by Canadian actor Nathan Fillion, who had previously lent his voice to other Bungie games, Halo 3, Halo 3: ODST, Halo: Reach, and Halo 5: Guardians.
- On July 17th, 2018, IGN announced that voice actor Nolan North would be replacing Nathan Fillion as the voice of Cayde-6 in Forsaken due to Fillion being unavailable at the time to voice the role. In the announcement, Fillion expressed doubt over his character being dead despite Bungie’s previous statements over Cayde-6’s official death.
