Flynn Rider, whose real name is Eugene Fitzherbert, is a character in Kingdom Hearts III.
Flynn has a somewhat selfish and narcissistic personality, although this gradually changes during his adventure with Rapunzel, whom he falls in love with. He was a cunning man who seeks to trick Rapunzel into escorting her back to her tower, forgetting about the journey to the kingdom due to him thinking this is all just a liability. Rapunzel's stubborn nature persists and she drags Flynn along with her. He is also seen slightly manipulative when he addresses Sora, Donald, and Goofy as his side kicks. His initial personality melts down and he shows a lighter and silly side after arriving in the Kingdom when he participated in the kingdom dance, only for him to be paired with Rapunzel at the last second.
Flynn is shown to be courageous, marching with Maximus by passing through a horde of Nobodies and Heartless that stands in his way to reach Rapunzel's tower. In his last breath, he cuts off Rapunzel's hair and confessed that she was his dream before dying, which shows the short adventure they had was enough to make him fall for her.
Flynn is of average height and build with fair skin, short dark brown hair, a scruffy goatee, and light brown eyes.
As far as attire goes, Flynn regularly dons a dark turquoise vest with a white long-sleeved shirt underneath, coupled with dark cream pants and brown bucket-top boots. He also wears a belt with a similar color scheme around his waist; connected to it is a miniature satchel.
Flynn flees from several Heartless in a forest, but is rescued by Sora, Donald, and Goofy. After his rescue, he slinks away and enters a nearby tower where he meets Rapunzel and Pascal. Using a tiara he stole, Rapunzel blackmails him to help her embark on a journey to see the flying lanterns. Wary of the Heartless prowling about, Flynn recruits Sora and company as his "sidekicks" to fight them off. Later, Flynn is persuaded by Rapunzel to let Maximus come along. At Corona, Flynn and Rapunzel are ready to watch the lanterns. Although Rapunzel is concerned it will not be like her imagination, Flynn tells her that she can find a new dream anyway. Flynn and Rapunzel have a nice time watching the lanterns fly. However, he mysteriously leaves with his crown on a boat, which breaks her heart. Unknown to Rapunzel, he has been knocked unconscious and tied-up by Marluxia. Eventually, Flynn is caught by the guards and is sentenced to death for his crimes by hanging.
The next day however, he manages to escape his death sentence with Maximus. While fleeing Corona, he sees Sora, Donald, and Goofy, and has the three of them ride on Maximus with him to rescue Rapunzel. The group returns to the tower, although Flynn gets there first. Inside, Flynn finds Rapunzel bound and gagged by Mother Gothel. As he enters, Gothel stabs him from behind, leaving him to die on the floor.
Rapunzel begs Gothel that if she lets her heal Flynn with the powers of her hair, Rapunzel will do whatever Gothel asks, even sacrificing her freedom for the rest of her life. Gothel accepts, and while Rapunzel tries to help Flynn, he tells her that if she heals him, she will die. Having realized that Gothel has used Rapunzel for her hair's healing properties, he chops off her hair with a mirror shard, causing her blonde hair to become brunette and destroying its power, which causes Gothel to die.
Rapunzel holds Flynn as he dies and they reveal to each other that their new dream was being together. As Rapunzel, Sora and the others mourn for Flynn, Rapunzel's tears allow her remaining power to revive Flynn. Flynn takes Rapunzel back to the Kingdom to see her real family, after revealing his real name Eugene Fitzherbert to Sora and his friends.
Sometime after Xehanort's defeat, Rapunzel and Eugene embrace in the town of Corona.
Flynn Rider is one of the main characters in the 2010 Disney film Tangled.
