Lucas & Oliver

Lucas & Oliver is the family ship between Lucas and Oliver from the The Promised Neverland fandom.

Canon
Although Lucas is not Oliver's biological dad, Oliver considers him as the only dad he has ever had. Lucas saved Oliver's life while he was running for his life in the Demons' hunting ground. And from then on, Lucas took Oliver "under his wing". He gave him a family in all the other Goldy Pond children he had rescued. He taught him valuable skills. And he was tender, caring and kind with him when Oliver needed it the most.

During the Goldy Pond battle against the Demons, Lord Bayon was planning to assassinate Lucas to eat him. As soon as Lucas realized this, he got in front of Lucas to protect him from Bayon's attack. Lucas was quick to shoot Bayon, however Bayon was able to insert his claws into Oliver's stomach before dying, which gravely injured Oliver. Extremely worried about him, Lucas takes him with the rest of the children, to treat his injuries and stop his bleeding. Despite all his stress and worry, Lucas smiles at Gillian who was also severely injured, and tells both her and Oliver that they'll do everything to save them both.

However, as more and more casualties ensue, and as a heavily injured Emma is brought to the cave by Yuugo, the team starts getting more and more desperate seeing they don't have much options of saving Emma. Oliver, who had already woken up from his unconscious state, then says he is willing to sacrifice himself to save the dying Emma, telling Lucas to leave him there to die. Shocked, Lucas firmly tells Oliver to quit it, thinking he'd never be able to do such a thing. And that's when Oliver tells him that he is incredibly grateful to Lucas for giving them a life, education, training, and more importantly, a reason to live and a family. With a weak smile on his face he asks Lucas if having a father would feel like what his bond with Lucas feels like. Oliver confesses that Lucas means the world to him and that he raised all of them like a father would. Although Lucas is deeply touched by his words, he reiterates that he would never let anyone behind and helps the children carry Oliver with them back to the Shelter, to be safe and to get healed.

After Lucas and Yuugo sacrifice themselves to save the children when their shelter is found by Peter Ratri's people, Oliver is devastated by the news. Later on, when they meet Peter Ratri again at the Grace Field House and he tells the children that he is their creator, and therefore their dad, Oliver is seen extremely angry and offended by this, thinking through gritted teeth that he is definitely not. Having flashbacks of Lucas and all the moments they spent together, Oliver thinks that the only dad he ever had was Lucas.

Fanon
Lucas and Oliver's father-son relationship is seen with tenderness within the fandom. Although it is not such a popular family ship like others are, like the family ships Isabella and the children have, it's very beloved overall since many have come to appreciate and love the father-son relationship the two of them have, especially considering Oliver is not Lucas' biological kid. Since most of this duo's scenes were not even animated in the anime, many fans felt sad and disappointed that they couldn't get to see many of their most memorable moments animated. One of the most loved moments between the two is the one where Oliver declares that his only dad is Lucas.

This father-son relationship currently has only 15+ works on AO3.
