In the film, when a regular guy (Wilson) dumps a superhero (Thurman) for her neediness, she uses her powers to make his life a living hell.

After several dates, Jenny displays increasingly neurotic and aggressive behavior, becoming more demanding and ultimately injuring Matt and destroying his bed the first time they have sex.

Soon after, Jenny reveals to him that she is in fact the voluptuous blonde superheroine G-Girl, who received the powers of flight, superhuman strength, speed, heightened senses, invulnerability, super breath, and heat vision after being exposed to radiation from a crashed meteorite as a teenager.

She uses her superpowers to publicly embarrass him, throwing his car into space and eventually causing him to lose his job as an architect by stripping him naked during an important meeting.

Fed up, Matt contacts Professor Bedlam; at his house he accidentally sees a room in which he has a shrine showing his secret continuing adoration of Jenny.

Professor Bedlam appears, but reveals that he has no intention of keeping his promise to retire from villainy and in fact plans to take the powers for himself.

She saves Matt, and the second fight between Hannah and Jenny is a full-on super-brawl, destroying part of the neighboring properties.

The website's consensus reads: "My Super Ex-Girlfriend is an only sporadically amusing spoof on the superhero genre that misses the mark with a nerd-turned-superwoman who embodies sexist clichés.
