Season 1: The 1986 Ulrich (Ludger Bökelmann) is a rebellious troublemaker who grows up to marry his high school sweetheart, Katharina, and become both a father of three and a detective in 2019 (with the older Ulrich played by Oliver Masucci). By the end of the season, the 2019 Ulrich gets trapped in 1953 while searching for his son Mikkel — while there, he attempts to kill young Helge Doppler so that he can't be involved in Mads or Mikkel's future disappearances. He's arrested while running away bloodied from the scene with Helge by Egon Tiedemann, who is looking for information on the recently-discovered bodies of Erik Obendorf and Yasin Friese.
Season 2: After getting trapped in 1953 and arrested on suspicion of murder, Ulrich refuses to identify himself or confess and is placed in a psychiatric facility. Therefore, in the second season we see the 2019 Ulrich aged 33 years (played by Winfried Glatzeder) living in the hospital in the year 1986. He's visited by a then-retired Egon, who shows him a photo of a boy who recently mysteriously appeared in Winden: Mikkel. Ulrich breaks out of the facility and attempts to run off with Mikkel, but is caught and arrested again.
Season 3:
- Adam's World: In Adam's World, Ulrich is still living in the psychiatric facility in the 1980s as an old man. He's visited by 2020 Katharina, who travels to '87 through the caves at the end of season two, and has been looking for Mikkel, who's in protective custody following Ulrich's visit to him. She promises him she'll get him out of the facility, but is unable to, so the last time we see him, he's facing the door, waiting for her like a lost puppy.
- Eva's World: As of the fall of 2020, Ulrich is divorced from Katharina and married to Hannah, who is expecting the couple's baby soon. Ulrich still ends up suspecting Helge has something to do with Mads's disappearance in 1986, but this time, Ulrich enters the caves behind 2020 Helge, where he ends up coming face-to-face with 1986 Helge on the other side. Similarly to how he smashes in young Helge's ear in 1953 in Adam's world, Ulrich smashes in 1986 Helge's left eye and leaves him to die in the bunker, where, surprise!, 2020 Helge comes out of nowhere and kills him with, ahem, a crowbar.
- Origin World: Ulrich doesn't exist in the origin world, as his grandmother, Agnes, and father, Tronte, can't be born without time travel.
