Characters in Sense8 who live in Berlin, Germany, home city of Wolfgang Bogdanow.
Wolfgang's best friend and partner in crime.
- Childhood Friends: He and Wolfgang have had each other's backs since they were kids.
- Distressed Dude: Wolfgang has to protect him after he's shot by Steiner. He ends the first season comatose in a private hospital.
- Family of Choice: To Wolfgang, who considers him a true brother (unlike the rest of his family, whom he hates).
- A Friend in Need: As seen in the Christmas special, while on the run from gangbangers with Wolfgang, despite after already surviving being shot before, and even with Wolfgang demanding he split off and get to safety, Felix staunchly refuses to abandon Wolfgang.
- Genre Savvy: He's watched his fair share of action films, and is aware that he fills the "sidekick" role in Wolfgang's storyline.Felix: ...I can't get shot again, that would be terrible plotting.
- Heterosexual Life-Partners: With Wolfgang, since childhood.Wolfgang: He's my brother. And not by something as accidental as blood by something much stronger. By choice.
- Moment Killer: He's the one who interrupts Wolfgang and Kala's Almost Kiss.
- Nouveau Riche: After stealing the diamonds Steiner had planned to steal, Felix gets excited about all the money he and Wolfgang are going to get for them. When they go to dinner at a fancy restaurant, Felix orders "the most expensive wine [they] have".
- Only Friend: Wolfgang mentions that Felix was the only kid who didn't hate him.
A Russian mobster who also happens to be Wolfgang's cousin.
- Bald of Evil: Steiner doesn't have a single hair on his head or a single moral in his body.
- Big Brother Bully: He has this dynamic with Wolfgang, though technically they're cousins. However they were raised together after Wolfgang's father died, so Steiner is more like a (terrible) brother than a cousin.
- Gangland Drive-By: This is how he shoots and nearly kills Felix.
- Hair-Trigger Temper: His self-control is practically non-existent. There's not a single scene with him in which he doesn't threaten, insult, or shout at someone.
- Jerkass: He's a violent, vulgar, and all-around unpleasant thug.
- Large Ham: Tends to deliver his lines in an over-the-top manner, often accompanied by similarly melodramatic hand gestures. Actor Christian Oliver clearly has a lot of fun with his role.
- Oh, Crap!: He has an appropriately epic reaction to Wolfgang shooting a rocket at him.
- Politically Incorrect Villain: He makes a few homophobic comments when Lito in Wolfgang's body lies to him about how they obtained the diamonds. For bonus points, Lito is a gay man (although Steiner's unaware of his presence).
- Sir Swears-a-Lot: His speech is riddled with obscenities.
- Smug Snake: Steiner thinks he is far more clever than he is. Wolfgang shows him up from their first conflict.
- Tattooed Crook: His bald head lets him display his neck tattoo of the Virgin Mary holding a gun.
Wolfgang's paternal uncle and father to Steiner, seemingly the head of the organized crime unit Wolfgang works in.
- Ain't Too Proud to Beg: When Wolfgang comes to kill him, Sergei desperately tries to bargain for his life, first by apologizing for ignoring the abuse Wolfgang was subjected to as a child, then by offering him money. It doesn't save him.
- Affably Evil: In stark contrast to his thuggish son, Sergei is unfailingly polite in his interactions with Wolfgang.
- Betrayal by Inaction: He allowed Wolfgang's father to take his mother away without protecting her. This is why he wants revenge so badly.
- Boom, Headshot!: The cause of his death, although it's not a single shot, but a whole magazine worth of bullets. The result isn't a pretty sight.
- Crazy-Prepared: Wears a bulletproof vest at home. Wolfgang immediately lampshades how unlikely this is.
- Et Tu, Brute?: Sergei is genuinely horrified when Wolfgang betrays him and admits to killing Steiner and his own father.
- Even Evil Has Loved Ones: He obviously cares deeply about Steiner and has stated that he wants nothing more than to get revenge for whoever killed his brother (Wolfgang's father).
- Even Evil Has Standards: He may be a ruthless mobster, but he draws the line at killing family members. He is accordingly shocked when Wolfgang confesses that he killed both Steiner and his own father.
- Like a Son to Me: Implied as much; Sergei tells Wolfgang that he doesn't want to choose between Steiner and Wolfgang (who does not reciprocate the feeling).
- The Mafiya: A high-ranking member of the Russian mob in Berlin.
- Man of Wealth and Taste: He lives in a huge, opulently furnished mansion, smokes fine cigars, and wears expertly tailored bespoke suits.
- Multiple Gunshot Death: Wolfgang riddles him with bullets to prove to Kala that he's a terrible person.
- Softspoken Sadist: He rarely raises his voice, which only makes him more threatening.
- Villainous Breakdown: Once it dawns on him that Wolfgang killed Steiner, his self-control rapidly fades, until he's firing wildly at Wolfgang while screaming in rage and grief.
- Wicked Cultured: Seems to be a lover of the fine arts, judging by the numerous paintings in his mansion.
One of the four major Berlin crime lords. He approaches Wolfgang in season two.
