Cayde-6 was an Exo who served as Hunter Vanguard. Cayde was also the owner of the Ace of Spades. In Destiny, 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. 
Through the lore book, The Man They Called Cayde from Forsaken, many truths and insights into Cayde's character are revealed. Before Forsaken, there were many comments and several lore entries where Cayde detailed the personality of his wife and son from before he was a Guardian; however, in the final lore book he admitted those were lies. He said that he remembered nothing about them, save that he loves or loved them, ultimately chalking it all up to the fact that it was their memory. As false as it was that kept him going, building him into the beloved hero, ultimately advising the Guardian that it may be wise to do the same if it helps them hold true to their path.
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 hidden away was a preserved 1883 copy of Treasure Island. The book was hidden in the Speaker's personal library and contains drawings and notes from Cayde within the book.
Death and Legacy
At the beginning of Forsaken, Cayde, Petra Venj, and the Guardian attempted to stop a riot at the Prison of Elders. Cayde was separated from the others and found himself facing off against a horde of Scorn. Although he was injured in the fight, Cayde managed to beat the horde that was attacking him. Cayde's ghost, Sundance, was then suddenly shot and destroyed by Pirrha, the Rifleman, right as she had begun healing him. Cayde, now vulnerable, faced down the Scorn Barons and was smashed through a wall by Reksis Vahn, the Hangman. He eventually regained consciousness and was greeted by Uldren Sov. Still weak and powerless, and after a short conversation, Uldren dealt the final blow by shooting Cayde with his own weapon, the Ace of Spades.
Cayde-6 has four memorials dedicated to him in the Tower:
- A framed picture of him smiling and giving a double thumbs up in the spicy ramen shop.
- An engraving of the Ace of Spades that can be found right behind Zavala.
- His own cloak located behind Amanda Holliday.
- His pet chicken, the Colonel, standing where Cayde stood as a vendor in the Tower.
In Forsaken, it is revealed that Cayde hid 10 caches all throughout the moon Titan with pre-recorded messages addressed to the individuals whom he believed might have been the one who killed him, or that Cayde otherwise knew on a personal level (many of the recipients falling into both categories). These people included Eris Morn, Taniks the Scarred, The Drifter, Petra Venj, Suraya Hawthorne, any Hunter who killed him, Zavala, Ikora Rey, and the playable Guardian.
Despite his diligence to his work, Cayde longed for the opportunity to get back into combat (The cause of how he died, as he was murdered during a mission at the Prison of Elders, the event which started Destiny 2: Forsaken). After speaking with Cayde-6 in Destiny, he would sometimes say things like “I need to get back in the field.” or even whisper “Hey, take me with you.” which further reinforced this idea. He was also a gambler, placing bets on the outcome of several events. Despite being a skilled Hunter, Cayde is often facetious and makes flippant remarks, even in the face of his own demise. However, when aggravated, he abandons his carefree demeanor and becomes more thoughtful and even vengeful. He remembers that when he was resurrected as a Guardian, he awoke to nothing but sadness, loneliness, and pain; the destroyed journal he kept of his life before becoming a Guardian is the only hint as to who he was.
Cayde's personality before he was turned into an Exo is unknown, as he was transformed right around The Collapse, supposedly being part of a deal to get him out of debt. He does not remember the facility where he was transformed well, other than that it was a cold and dark place with pain.

- Cayde-6 was voiced by Canadian actor Nathan Fillion, who had previously lent his voice to other Bungie games, Halo 3, Halo 3: ODST, and Halo: Reach.
- 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.
