Jonas Kahnwald, better known as Adam, is the main antagonist of the German 2017 Netflix-series Dark. He is the future self of the main protagonist Jonas Kahnwald, who wants to end the so-called time knot, which is a time-loop that has caused many problems and misery for people. While he isn't actually evil, Adam believes that the only way to end it is to end the universe altogether, and takes extreme measures to do so, so people don't have to experience the misery caused by it.
He was portrayed by Dietrich Hollinderbaumer in most of his appearances, and Andreas Pietschmann as his younger self in Season 3.
Adam is highly intelligent and conniving in nature, due to the knowledge of future events. He also doesn't hesitate to manipulate his staunchest allies to do whatever he wants to let things be as they were. Due to which, he doesn't value their lives very much, demonstrated when he orders his former best friend Bartosz's death due to his disillusionment regarding Adam's plans, and directly causing his parents' deaths to perpetuate the Knot.
That said, he doesn't hold any personal malice towards his enemies due to considering them equal sufferers in the Knot, demonstrated when he aids his younger self and Claudia eventually to escape the misery of the endless time loops. He is also immensely nihilistic, truly believing the end of his universe is the only way to escape the machinations of time, and eager to go any lengths to achieve it.
When Jonas, whose is one of the many whose existence is dependent of the time knot, tried to find a solution for making things go back to the way they used to be before him and his friends entered the time loop in a cave in the town of Winden.
Jonas found out that his father is Mikkel Nielsen, a missing child from his timeline who accidentally went back in time through the cave. (Adam, as Jonas, will eventually cause his disappearance.) Eventually after growing old and escaping the Apocalypse with his friends, he decides to end the knot. Knowing that ending the time knot would erase his and many others existences, he traveled through different timelines, recruiting different people from said timelines, and formed the cult known as Sic Mundus, also known as The Travelers, and adapted the name Adam with the goal of ending the universe, to end the time knot.
In 1911, Stranger Jonas (now completely becoming Adam) received 2 guests, his mother Hannah Kahnwald and her daughter Silja, sent there with the help of Eva. In order to test if his mother's presence will deter him from ending the Knot, he personally kills Hannah and sends his half-sister Silja to 2041.
He convinced Hanno Tauber, the son of his half-sister Silja and his friend Bartosz, to kill Bartosz, and convinces his older self from 2041 to adapt the name Noah and adapt the facade of a priest, and use the chair as an experiment, resulting in the deaths of 3 children. But instead of ending the universe, he said that their goal was to elevate humanity using time travel, to re-arrange event for their wishes. Adam promised Jonas when he came from 2053 that saving Michael will end the knot, while he was setting him up to cause Michael's suicide. Adam also promised the older Noah that this would lead to him eventually reuniting with his girlfriend Elisabeth and daughter Charlotte, while Adam himself orchestrated the kidnappings and blamed Claudia. After taking the missing pages of the triquetra notebook after killing the old Claudia Tiedemann, who is against Adam's plan, Noah found out that he had been used by Adam and that his goal he told him was a lie. Noah went to the headquarters and tried to shoot Adam, but Adam explains that he can't be killed by him since his fate is predetermined, and it isn't to be killed by Noah. Becoming a liability to him, Adam has Noah killed by his own sister Agnes.
Adam later travels to 2020, in time for the reunion of his younger self with Martha. Jonas, now fed up with Adam blames him for the misery around them. Adam agrees, but states everyone is the trigger, as he shoots Martha to influence Jonas to become him. Adam circles the calendar at his house, stating his victory, and leaves them. Martha dies later in Jonas's arms.
Adam goes to 2053 to manipulate Martha Nielsen from Eva's World into working with him, and allows his younger self to begin the time-travel experiments. Then he sends his agents to various points in time, to perpetuate the time loop, while planning to end everything. Adam eventually betrays Martha to kill their unborn child in order to end the time knot, but fails due to the realities overlapping.
- Jonas's goals in time-traveling were to retrieve Mikkel, stop Michael's suicide, prevent the Apocalypse and prevent Martha's death. In a cruel twist, Jonas later became the cause and reason for all of them.
