David Hockney/History

History
Originally, David Hockney was an underling of Hell Joe. Alongside Yuliu Mata, he was tasked with searching for fragments of Enryu's Thorn in exchange for a way out of the Floor of Death. However, after he saw the first fragment, Hockney suddenly changed like he became a completely "different person" like he was possessed, and his soul was bonded to the "painting" that he drew at the site where the fragment was located. Afterwards, Hockney also refused to help Hell Joe. Enraged, Hell Joe violently took out Hockney's real eyes and tried to use them to find the rest of the fragments, but to no avail.

After being attacked by Hell Joe, Hockney's friend, Yuliu Mata took Hockney to meet Grand De Jah inside his castle located in the 43rd Floor North City and begged him to find a way restore his eyes. But it cannot be restored as Hockney's soul mysteriously vanished and was no longer contained inside The Spirit Room. Instead, De Jah offered his own "special eyes" to Hockney in exchange for him leaving the Floor of Death to find "The Savior" that everyone had been waiting for. However, after being implanted with De Jah's eyes, Hockney fell unconscious and lost all of his memories about the mission that De Jah gave to him. He later left the Floor of Death but continued to feel a sense of emptiness due to his incomplete soul, which was fragmented along with the painting binding it.

The Hell Train: Wangnan
Hockney first appears when the Hell Train enters the 40th Floor. He had been living near the station there called the Mushroom Farm. Hockney was seen observing the approaching Hell Train and when it finally arrived at the station, he left his residence and came to the Hell Express Altar to board the train's stairs, immobilizing his two old teammates, Jourdan and Arcu in the process as they were getting in his way. Sachi Faker who had heard rumors about him was surprised that Hockney got on board and asked if he had found who he was looking for, with Hockney clarifying that he was actually looking for the final piece of his original painting which was said to be on the train.

He is a native resident of the Floor of Death. He entered the Tower to reclaim a painting of his own making, the "Red Light", which was stolen from him and which he regards as his own soul. It was subsequently divided into six pieces, five of which he managed to buy back through special auctions reserved for Regulars. He eventually bought the very last piece and expects to obtain it on the Hell Express. Unbeknown to him, it is in the possession of Ha Yura. He then helped the others pass the final stage tests on the train before getting ready to go to the 43rd Floor.

The Hell Train: The Floor of Death
Having finally reached the Floor of Death, he and the others got ready to jump out of the train into the Floor. With Ha Yura and Karaka surprising everyone with their arrival and subsequent exit into the Floor, they all jumped in after them. While passing through the dead Guardian's blood, Baam suddenly fell unconscious and drifted away on another stream current with Hockney going after him.

Finding themselves separated, Hockney was soon encountered by his old acquaintance Yuliu Mata inside the giant creature that he controlled. Hockney told Mata of his plans to go to South City to retrieve the last piece of his soul, they were soon confronted by another Watchmen gatekeeper. Mata quickly defeated the hostile gatekeeper with Hockney's help to foresee the future. Travelling to the final gatekeeper's area, Mata told him to stay quiet so he could try and get the two in without them having to give up their souls.

Gakjadosaeng (Arc)
After the FUG forces crossed the second defensive wall of The Nest, they were forced to play Gakja Dosaeng game. All Baam's friends, including Hockney himself agreed to participate in the game so they were sent into The Cat Tower.

A Dark Twist
Inside the Cat Tower, Hockney ended up on the same location with Lo Po Bia Elaine and Rak Wraithraiser. The three of them visited Cat Tower Control Room and then played the Cat Tower Fishing Game. During the game, Hockney used his special eyes and imitation skill to gain as much Points as possible in order to help Baam and other FUG forces who were fighting on the Cat Map Floating Fields.

The Descent (Arc)
After the Cat Tower Fishing Game ended, Hockney and Elaine found themselves trapped in dangerous situation as Trughe explained the Cat Tower will self destruct by using the unknown bomb planted somewhere inside the area. They quickly try to figure out a way to escape. But Hockney suddenly felt a suffocating and ominous feeling due to the immense presence of Family Head Lo Po Bia Traumerei who at that time had arrived inside The Nest.

The Ten Great Family Leaders (Calamity)
After the Cat Tower exploded because Lo Po Bia Fucile committed suicide, all people inside the Cat Tower, including Hockney himself were all saved and rescued by FUG Elder Sophia Tan.
