Played by: Charlie Cox
- Action Hero: In the climax.
- Adaptation Name Change: Originally Tristran in the novel, but changed to the more conventional sounding Tristan for the film.
- Deadpan Snarker
- Expository Hairstyle Change: Shakespeare gives his hair extensions when he starts his training with the pirates and he takes a level in badass.
- Nice Guy: Despite the incredible Belligerent Sexual Tension between Yvaine and his rude behaviour toward her (of course, she doesn't make things any easier), Tristan is a very sweet and romantic guy.
- Snarkto Snark Combat: With Yvaine.
- The Reveal: He's the son of Princess Una, and therefore an heir to the throne of Stormhold. Everyone (barring Una) was completely unaware of this fact until the end of the movie... after all of Tristan's uncles have been killed, making him the only remaining heir and therefore the new king of Stormhold.
- Took A Level In Bad Ass: Halfway through the movie when he gets training from Captain Shakespeare and his crew.
Played by: Claire Danes
- Breakthe Haughty: A large majority of the movie is this for Yvaine.
- Deadpan Snarker: For a star who spent most of her life by herself in the sky, she sure can be quite snarky.
- Defrosting Ice Queen: Initially is very cold and rude to Tristan, but eventually warms up to him and even falls in love with him.
- Fish out of Water: She is quite naive and not exactly well-versed in human behaviour; for example she has no idea what a massage is.
- Power Glows: Her ability to shine when she's happy. However, it's more for than just aesthetic purposes, as Yvaine completely vaporises Lamia when she really shines.
- The Powerof Love: What allows her to defeat Lamia.
- Snarkto Snark Combat: With Tristan.
- Stars Are Souls: And in this case people, when they fall to Earth.
Played by: Michelle Pfeiffer

Empousa and Mormo
Played by: Sarah Alexander and Joanna Scanlan
- The Beastmaster: Mormo's main power. Though unfortunately, the animals eventually turn against her and maul her to death.
- The Hecate Sisters: Mormo takes the role of the Matron as she is rather plump and motherly-looking while Empousa takes the role of the Crone, as she is more spindly in appearance and seems the most bitter and sarcastic of the three.
- Impaled with Extreme Prejudice: Empousa gets stabbed through the chest by Septimus.
- Playing with Fire: Empousa's specialty.
