My Super Ex-Girlfriend

A film from the director of Ghostbusters starring Uma Thurman and Luke Wilson. The latter plays Matt Saunders; your basic everyman, who unwittingly ends up dating Superheroine G-Girl's alter ego. He finds out her secret, but soon also discovers that she's a Clingy Jealous Girl and breaks up with her for being controlling and dangerous.

She doesn't take it very well. Meanwhile, her nemesis hatches a plan to use this domestic dispute to depower her, and enlists Matt to spring the trap.

Tropes used in My Super Ex-Girlfriend include:

Acquired Situational Narcissism: Jenny acquires this along with her superpowers and became G-Girl, leaving poor Barry alone and embittered to become Prof. Bedlam.
Any Torment You Can Walk Away From. She ruins his entire life AND his car. She offers to pay for the car she ruined. He's somehow okay with that.
Alliterative Name: G-Girl's Secret Identity is named Jenny Johnson. It gets a Lampshade Hanging near the beginning.
Animal Assassin: G-Girl throws a live shark through her ex's bedroom window.
Applied Phlebotinum: The source of G-Girl's superpowers. (Specifically, Green Rocks.)
Beware the Superman: Particularly if they're a Clingy Jealous Girl and you're planning to break up with them.
Breast Expansion: Happen's as part of G-Girl's origin story.
Captain Ersatz: G-Girl is basically a female Superman, complete with a copy of Lex Luthor.
Casanova Wannabe: Matt's friend Vaughn. He finally gets laid after the credits.
Cat Fight: G-Girl and Hannah after the latter gets superpowers.
Clark Kenting: Wig + Nerd Glasses = Instant disguise!
Clingy Jealous Girl
Dating Catwoman: In the end, G-Girl and Professor Bedlam. He's implied to have switched sides though.
Destructo-Nookie
Do Not Call Me "Paul": Professor Bedlam does not appreciate being referred to as Barry.
Double Standard Abuse (Female on Male): The Movie. The film basically portrays a manipulative, controlling, physically and emotionally abusive relationship enhanced with superpowers, as a comedy. A Gender Swap would be the stuff of nightmares.
- Not that it's portrayed as exactly okay - but definitely less shocking/dramatic as it would be if gender-swapped.
Everyone Can See It: Between Matt and Hannah.
Everyone Loves Blondes: Includes the main guy going from the superheroine G-Girl to his crush, Hannah. What is odd is that, while G-Girl's hair turned blonde with her new powers, Hannah's hair actually turns from blonde to redhead.
- Justified, because Heroes Want Redheads.
- It seems the power turns redheads blonde and blondes into redheads.
Everything's Even Worse with Sharks: When G-Girl turns on Matt, she throws a shark at him. It almost kills him, despite his apartment being on dry land.
Exactly What It Says on the Tin: Guy dates a super-girl. Guy breaks up with super-girl. Super-girl is angry. Hilarity Ensues!
Eye Beams: On lower settings, they're useful for Face Doodling. Nothing wrong with shooting people in the head, right?
Fan Service Pack: An effect of the Green Rocks.
Finger-Suck Healing: Hannah sucks on Matt's finger to remove a splinter.
Flying Brick
Good People Have Good Sex: Subverted when we see Matt and Hannah have sex, after Hannah gets superpowers, in exactly the same way as Matt and G-Girl used to have sex.
Heroic Comedic Sociopath
Hypocritical Humor: Carla. Throughout the film, she practically considers men as always sexually harassing women, and pushing for the woman to file a complaint against the guy despite the guy doing nothing. During the credits, Carla goes up to a male employee and grabs his butt.
~~Kick the Dog~~ Burn The Fish
Kryptonite Factor: Played with. G-Girl's "kryptonite" comes from the same meteor that gave her her powers in the first place.
Mad Scientist: Professor Bedlam.
Magic Meteor
Man of Wealth and Taste: Lampshaded.

Professor Bedlam: I'm not a Super Villain! I'm just smarter, wealthier, and have better taste than you.

Most Common Superpower: Exposure to Green Rocks made G-Girl grow a few cup sizes.
Mundane Utility
Nigh Invulnerable: Even her hair. One wonders how she gets it cut.
- Her heat vision?
Psycho Ex-Girlfriend: with SUPERPOWERS!!!
Right Through His Pants
Romantic Comedy: With superheroes!
Sassy Black Woman: Carla, in a weird pseudo-Straw Feminist sort of way.
Shamu Fu: Again, G-Girl threw a LIVING shark at her ex. That'll learn 'em!
Shaped Like Itself: One character describes G-Girl as "spinning like a spinny thing."
Shiny Midnight Black: The Romantic False Lead in the way of Matt and Hannah's relationship has hair like this. Probably due to the lighting but the trope is much in effect.
Stephen Ulysses Perhero: Professor Bedlam's real name is Barry Edward Lambert.
Super Speed
Super Strength
Suppressed Rage: When Matt first mentions "needing space", Jenny's OK with it...until he mentions dating other people, when she slams the knife she is chopping carrots with into the board. And then frighteningly, bends it with her bare hands.
Victorious Childhood Friend: Professor Bedlam.
With Great Power Comes Petty Revenge
Yandere - and a super-powered one at that.
