Basic Trope: Character's new love interest turns out to be evil.
- Straight: Bob's new crush, Evi Lynn, is later revealed to work with the Big Bad Emperor Evulz.
- Exaggerated: After that, Bob gets several more love interests but they also turn out to be evil.
- Downplayed: Only "evil" insofar as being unkind to the point they can't get along.
- Justified: Evi figures she can play a long game by integrating herself into Bob's social circle in order to mislead him for as long as she needs to.
- Inverted: Bob turns out to have been the villain all along, seducing the new love interest.
- Subverted:
- Evi turns out to be genuinely nice despite appearing evil.
- Evi reveals herself to be a doppelganger to Bob after betraying him, and also reveals that she murdered the real Evi.
- Evi was evil but ended up Becoming the Mask and does a Heel–Face Turn.
- Evi is Good All Along and has a plan to take out the Big Bad, but for her plan to work, she has to get close to him and get him to lower his guard. To make her Face–Heel Turn seem real, she pretends to betray the good guys.
- Double Subverted:
- ...but then it later turns out that she was only faking being good.
- The Big Bad manages to get her to see things from his perspective, so she pulls a Face–Heel Turn for real.
- Parodied: Evi Lyn lets out an Evil Laugh as soon as Bob asks her out, and he notices nothing.
- Zig Zagged: ??
- Averted: The new love interest genuinely is a good person.
- Enforced: The author wants to make a point about how love can sometimes blind us to who someone really is.
- Lampshaded: "Wow, the new love interest was bad all along? What are the odds?"
- Invoked: ??
- Exploited: ??
- Defied: Bob makes sure everyone he gets involved with is good.
