"This time, you're the only Superman we need."
Lillian Luthor to Jeremiah Danvers[src]

Dr. Jeremiah Danvers (died 2020) was a scientist, the husband of Eliza Danvers, the father of Alex Danvers, and the adoptive father of Kara Danvers. While seemingly dead for 12 years, he was in reality made an unwilling member of Project Cadmus.

In 2020, three years after his family learned of his survival, Jeremiah was found dead, due to being killed by Eve Teschmacher under the orders of Lex Luthor.


Original multiverse

Early life

Jeremiah was a brilliant scientist living with his wife, Eliza, in the small town of Midvale. In 1989,[1][2] the couple had a daughter together, Alex Danvers.

At one point in time, Jeremiah and Eliza met Superman, whom they helped to understand his own abilities.[3]

Taking in Kara

Eliza and Jeremiah Danvers welcomes Kara into their family.

When Superman discovered his cousin Kara Zor-El, he and his wife took her into their home. He asked Alex to be a sister to Kara.[3]

Kara was enrolled at Midvale Junior High School along with Alex. Kara was freaked out by her new world along with her developing powers. When they went to the beach, she embarrassed Alex by staring at the birds as they did not have them on Krypton. When a car crashed close by Kara ran to the rescue saving a mother and her child. However, Alex was injured by a car door when it exploded. Jeremiah spoke with Kara telling her that Alex was fine and it was just a few stitches. After that Kara decided to hide her powers, with Jeremiah telling her that they already have a Superman and to just be herself. He gave her a pair of lead-lined glasses to help her control her visual powers.[4]

Joining the D.E.O.

One evening Eliza went outside to the porch to get her husband Jeremiah to keep her company while she worked on her dissertation. On the roof, Kara convinced Alex to sneak out and go flying with her, despite the latter's initial protests. While holding onto Kara as she flew, Alex told her that it was amazing. Kara and Alex were caught sneaking in by Eliza and Jeremiah, and lectured about the rules. After someone knocked on the door, the girls were sent up to their room, with Eliza telling Kara not to use her super hearing to listen in on their conversation. Answering the door, Hank Henshaw along with two associates requested to speak with the two. They gave him an ultimatum: work for the D.E.O. or they would take Kara into custody.[1]

Apparent death

Jeremiah meets J'onn J'onzz.

While on a mission to locate J'onn J'onzz in a remote location in Peru, he realized J'onn wasn't a threat but a refugee. Jeremiah tried to stop the mission but Hank became obsessed and refused to. When Hank finally trapped J'onn, Jeremiah sacrificed his life to stop Hank. As he apparently died, J'onn made a promise to take care of Jeremiah's daughters.[5]

Project Cadmus

Jeremiah's body as well as that of Henshaw's was subsequently found and taken by Project Cadmus. The group forced Jeremiah to reanimate the former director of the D.E.O. with cybernetic parts, turning him into a cyborg. Jeremiah attempted to escape multiple times but was always captured by Cadmus' guards and tortured as a punishment. When Cadmus threatened to hurt his daughters if he refused to comply with his demands, Jeremiah surrendered[6] and forcibly became one of their agents, receiving some cybernetic enhancements as well.[7]

When J'onn later tried to erase Jim Harper's memories he learned that Jeremiah Danvers was still alive and being kept at Cadmus.[4]

When Kara and Mon-El were captured by Cadmus and imprisoned in one of their hidden bases, Jeremiah, who had access to Cadmus IDs, rescued them. After removing some lead from Mon-El's injury, he helped the duo escape but chose to remain behind for unknown reasons.

Afterwards, Kara and Alex led a team of D.E.O. agents to where Cadmus imprisoned Mon-El and Kara, only to find the site empty, with no sign of Jeremiah.[8]

Return and betrayal

Jeremiah reunites with his daughter and the D.E.O.

The D.E.O. got an alert from one of Cadmus' suspected bases and found that they were moving a weapon in a convoy. Supergirl and Martian Manhunter went to stop them and saw that what they were transporting was really Jeremiah. Jeremiah was welcomed back to the D.E.O. with cheers and was happily reunited with his daughter Alex. He told them that Cadmus took him from the rainforest and forced him to enhance Hank Henshaw for their own ends but said that he did too good a job and kept him to enhance others as well as build for them. He tried to escape a few times but punished him when they did. Alex saw that his right arm had extensive nerve damage to it. He then told everyone that Cadmus now had a new fusion bomb that they made when they took Kara's heat vision when they captured her and would use it on National City and blame hostile aliens for the devastation.

He was then reunited with his wife Eliza and everyone decided to celebrate at Kara's apartment.

Jeremiah met Alex's girlfriend Maggie Sawyer and watched as Alex and Kara were with their new relationships and told Eliza that he really missed a lot. Eliza told him that they would just have to start over, even when it came to the two of them. J'onn then announced that Jeremiah would be re-instated back with the D.E.O. but Mon-El thought that Jeremiah returning to having his old job and access was a little too fast. Kara pulled him aside to wonder why he was being so suspicious of Jeremiah when the man offered to walk Mon-El out. Mon-El tried to apologize but Jeremiah told him that he knew who Mon-El really was. He also told him that he didn't think Kara would be happy when she learned the news as well. With that, he then left Mon-El in the hallway and returned to the others.

J'onn took Jeremiah to the D.E.O. where he saw that the place had changed and J'onn said that it was thanks to his daughters. Jeremiah told J'onn that its natural for the young to demand change but J'onn was the one that was opened to it. J'onn then left Jeremiah to go and oversee the hunt for Cadmus' weapon and he went to try and access the D.E.O. mainframe and was caught by Winn. Winn had gone to Mon-El and they went to Kara about his suspicious behavior and Kara went to confront Jeremiah about it and he told them that he just wanted to try and catch up with all the things that had happened while he was away.

When they had a lock on the weapon, Jeremiah stayed with J'onn to oversee the operation but when Kara, Alex and Mon-El got there, the place was empty.

Jeremiah then moved to slip away but he was noticed by J'onn who wondered why he couldn't read Jeremiah's mind. Jeremiah made his way to the mainframe when J'onn confronted him and saw that his injured arm was actuality cybernetic. Jeremiah said that he'd changed before he then attacked J'onn, Winn and the D.E.O agents that tried to stop him from trying to copy some files. J'onn saw that Mon-El was right about him but Jeremiah said that it was more complicated than that before he seriously injured J'onn and fled after sabotaging the mainframe to cover his tracks.

He then met up with Lillian Luthor and Hank Henshaw at the woods outside National City but they were found by Kara and Alex due to Winn having placed a tracer on Jeremiah. They then revealed that they had placed bombs on a train track which Kara went to try and save. leaving Alex to confront her father. Alex told Jeremiah that he was bringing him in but Jeremiah said she wasn't going to. He claimed that what he was doing had been for her, but she pointed out that he betrayed the D.E.O. and their family and he said that it was complicated. He then stood out and told Alex to shoot him if she wanted and he would understand if she did. However, she found that she couldn't and Jeremiah walked off, leaving her brokenhearted. It was later discovered that what he had stolen from the D.E.O. was the registration list of all the aliens living in the country.[7]


Jeremiah was classified by J'onn as a threat to the D.E.O. and was ordered to be arrested and detained on sight. Alex went off on her own to find Cadmus and discovered their base of operations, but was quickly found and detained by Jeremiah. He showed her a space frigate (type Hoshin, "best in the Karark fleet") that Cadmus was using to conduct Operation Exodus. They were taking all the aliens in the registry and putting them on board a ship, which would make a hyperspace jump to the other side of the universe, where the aliens would receive shuttle back to their home worlds.

Alex was shocked that her father was helping to forcibly deport all the aliens but he explained that Lillian wanted to have them killed before he convinced her to do it this way instead.

Jeremiah still claimed that he was doing this for her, to protect her and Kara from Cadmus. When Lillian returned, she revealed that Kara had printed an article online that exposed their whole operation and they needed to send all the aliens they had away now. However, Alex revealed that she had planted explosives throughout the base and detonated two to show she wasn't bluffing. She pleaded Jeremiah to help her stop Cadmus' intentions. When Lillian started the launch, Jeremiah moved to help Alex. Lillian then set Hank Henshaw loose upon him. After a brief battle, Jeremiah was thrown from the scaffolding they were fighting and taken again.[6]

A couple months later when Alex confronted Lillian, demanding to know where her father was, Lillian claimed she didn't know.[9]

Anti-Monitor Crisis

During the Anti-Monitor Crisis, Jeremiah as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019,[10] only to be restored a month later, after the Paragons and the Spectre created a new universe.[11]

New multiverse

Jeremiah gave Alex the responsibility of protecting Kara Zor-El when the Danvers family adopted Kara.[12]


Lex Luthor lied to Eve Teschmacher stating that a man under the name "Jason Ford" killed her father. In return she killed the man in the Peruvian Andes. Lex Luthor then told her that it was Jeremiah Danvers and not Jason Ford.[13]

In early 2020, Alex received a call from her mother, Eliza, informing her that Jeremiah had been found dead from an apparent cardiac arrest (heart attack) inside his apartment, leaving both Alex and Kara angry and upset. [14]


Jeremiah's murder led both his daughters astray from each other; being taken back by his demise, Alex fell into alcoholism just like the aftermath to his first presumed death, and the use of the Obsidian Platinum technology. She used it to cover up her pain of losing Jeremiah, but eventually she realized she was just ignoring the reality of it.[15]

Both Kara and J'onn had also dealt with this loss in their own way. Greatly saddened due to all the good Jeremiah had done for her in making her feel human, Kara, frowning often, spent time mainly to herself away from the Superfriends.

Lex's plan that the assassination of Jeremiah would distance Lena and Kara was unsuccessful because their friendship was too strong.[13]


Jeremiah was proven to be a loving parent willing to protect his family.

Jeremiah was one of the few humans who did not have an anti-view on aliens in general; as evidenced by the fact that Jeremiah raised Kara Danvers as his own daughter, despite the latter not being human, as well as the fact that he was forced to work for the D.E.O., in order to prevent Hank Henshaw from taking Kara away, in attempt to use her and abuse her as their own weapon.

Jeremiah had later felt that the ends justified the means as Cadmus caught up to him, even battling his friends and family, and deporting the aliens of the Earth to their home planets forcibly. He was eventually forced to rethink this way of thinking, but even when doing these extreme measures, he always did so for both his daughters.
