Stephen Shin is a marine biologist who befriends lighthouse keeper Tom Curry and his son with the sea-dwelling Atlanna, Arthur Curry, the future Aquaman. He has more knowledge of Atlantis than any other surface-dweller. Shin helps Arthur develop his powers, but turns on his protege when he refuses to reveal the location of Atlantis.^[2][3]

Some years later, Aquaman and Mera visit Shin, asking for his help to identify strange sea creatures. He does, but is angered again when Aquaman refuses to let him keep one.^[2][4]

Aquaman and Mera visit Stephen Shin to see if he can help figure out the Atlantean artifact that they have and if he knows of the identity of the person who sank Atlantis. Shin states that it was possible for someone to sink Atlantis and mentions that it has enemies due to it being the most powerful civilization in the world. Aquaman stated to Shin that he caused a volcanic explosion that trapped the Trench. Just then, a woman named Ya'Wara breaks into Stephen's house in order to kill him only for Mera to take action. When Aquaman breaks up the fight, Ya'Wara tells him that Black Manta killed Kahina, took the gold seal that she had, and believed Stephen told Black Manta about it.^[5] As Ya'Wara believes that Stephen Shin is in league with Black Manta, Aquaman says that they need him to find the missing relics as Aquaman has Stephen start looking. He does warn Shin that if he is in any way connected to Kahina's death, he will allow Ya'Wara to feed him to her pet jaguar. Shin returns to work on the Atlantean black box as Mera asks him about Black Manta and what he knows about the Others.^[3] When Mera keeps asking Stephen Shin about Black Manta, he states that he hasn't seen Black Manta in years and explains that he met Tom Curry and his son Arthur years ago when Tom saved him from an expedition that went wrong. While he did get the knowledge of Atlantis during that time, Tom refused to have Arthur's abilities revealed to the media as Shin states that it can save his career. Then he tells Mera about a treasure hunter that he found shipwrecked off the coast of Iceland and had fought off a group of pirates. Mera believed that the treasure hunter was Black Manta which Shin confirms. Though he denied that Black Manta had a hand in Tom Curry's death by stating that Tom died of a heart attack and Aquaman later killed Black Manta's father.^[6] As Mera still doesn't trust Stephen Shin after he revealed Aquaman to the public, he states that he is not the man that she thinks he is while also explaining that Aquaman attacked Black Manta's ship where it was revealed that the captain was Black Manta's father while Black Manta was the diver at the time when Tom's funeral.^[7] When Black Manta arrives to abduct Stephen Shin, Mera fights him until Black Manta stuns Mera and teleports away with Stephen. Black Manta tries to get Stephen to help him at King Atlan's tomb only for Stephen to decline as he does not want to betray Aquaman again.^[8] After getting information from the Operative on where Stephen Shin was taken, Mera heads to King Atlan's tomb where Black Manta has the Dead King's Scepter in his hand as he orders his men to kill Stephen only to Aquaman to fight Black Manta's minions. As Ya'Wara believes Stephen to be responsible for Black Manta obtaining the Dead King's Scepter, she starts to attack only for Vostok to stop her saying that Stephen has regretted his actions.^[9] Stephen Shin still feels remorse for what happened to Tom Curry only for Aquaman to tell him that what happened to Tom wasn't his fault.^[10]

As Aquaman faced off against Ocean Master during the "Throne of Atlantis" storyline, Cyborg is instructed to protect Stephen Shin.^[11] Stephen Shin and Nuidis Vulko watch the news about the war from the computers of the Justice League Watchtower. When the reporters claim that Aquaman will betray the Justice League, Stephen refuses to believe that fact. Vulko reminds Stephen about his past actions towards Aquaman. He then attacks and knocks out Stephen while ranting about how he was banished after Aquaman left Atlantis.^[12]
