"Think of me as Yoda. Only instead of being little and green, I wear suits and I'm awesome. I'm your bro. I'm Broda."Are you a Chew Toy, A Woobie, a Dogged Nice Guy or just generally pathetic? Are women avoiding you like plague? Do you feel existentially lost in a cruel and uncaring universe? The Sensei For Scoundrels might be the answer to your prayers. He is everything you wish you could be as a man: strong, attractive, fearless and a huge success with women. Of course, he's also probably deeply disturbed, and possibly very evil. The main character winds up following The Sensei for Scoundrels in the hopes of becoming the kind of man he always wanted to be. In a Lighter and Softer story, the main character will very often end up rejecting the sensei's advice by the end and win the girl on his own terms. In Darker and Edgier works, the hero very often ends up becoming as bad as the mentor and loses all of his positive characteristics in the process. Of course, it's also possible the mentor is perfectly respectable and our protagonist will end up better for the experience. These guys also exist in real life, though they're usually not quite as psycho and probably are financially motivated. Compare and Contrast the Big Brother Mentor whose relationship with the protagonist is a bit more friendly and has fewer unfortunate drawbacks. There's a certain amount of overlap with the Manic Pixie Dream Girl, considering both are slightly unhinged characters who encourage a tightly-wound protagonist to relax and have a little more fun in his miserable life. See also Evil Mentor.

- Jack Rakan of Mahou Sensei Negima!. He might be smart, but he's definitely crazy and perverted, to the point that they only techniques he doesn't make up on the spot are the ones used to harass females. Of course, Negi specifically begins training with him because he wants to learn how to be more of an idiot.
- Considering how many girls are already tripping over each other just to be near Negi, he doesn't need the help.
- The Hentai anime The God of Groping.
- Kozue Takanashi does this for Yachiyo Todoroki in WORKING!! - Yachiyo is looking for advice on what she should do to get ready to hang out with a male co-worker, without any designs on romance. Kozue, a Hard-Drinking Party Girl who isn't shy about, well, anything, basically gives advice on how to get laid. Most of it flies over Yachiyo's head, though what doesn't manages to be useful.

- This trope was initially named for Tyler Durden in Fight Club who teaches the nameless protagonist to stop being so emasculated and to go Fight Clubbing as well as some other... matters.
- Tyler is an especially interesting example of this trope, as he's not actually a real person, but rather a wish-fulfilling, disassociated identity of the protagonist that does all of the things the protagonist wishes he could do.
- The Game is based off of Neil Strauss attending seminars on how to become a pickup artist. He eventually became one of the teachers himself.

- In Zap!, Gunner Strife tried to be one of these to Zap while training him in the use of psychic powers. It worked up until Gunner told him to use his psychic powers to make Leona fall in love with him. Zap decided to block Gunner from telepathically contacting him instead. Gunner didn't take it very well.
- Sam Starfall decides to take this role to Florence in Freefall, although by his scavenger species' Blue and Orange Morality, this is simply being a good mentor. Prior to the comic starting, he had also provided similar education to Robot Buddy Helix.
