You defeated the villains who Cursed You With Awesome—saving your loved ones in the process, turning some cynics into optimists, and using the only antidote for your mutation to selflessly cure the Littlest Cancer Patient. Your love interest still wants to be with you, even with your transformation and new powers... but you don't exist anymore. You're a freak. You tell her the man she loved is gone, you're something else now, and you leave. She cries your name as you walk away into the night - to save the innocent and help the helpless.
Type 1 - Physical: The protagonist either is a newly-minted superhero or has transformed into a hideous yet benevolent creature. He must abandon his initial goals and romance to either walk the hero's path alone or find a means to counteract his current transformation (good luck with that). The hero must tell his love interest that the man she loved is gone; only the heroic persona or hideous yet benevolent creature remains.
The hero must abandon his love interest because his very presence will deprive her of the normal life the love interest deserves. In the more optimistic and less creature-related examples, he must also leave because their love interest will never be safe from villains if he stays.
Type 2 - Social: The hero purposefully denies or is denied acknowledgement of his actions for the greater good of society.
Whatever type is invoked, it's helpful if it is followed by an emotionally resonant and important monologue.
Anime and Manga
- The OVA Guyver: Out of Control features Sho Fukamachbi playing a variant on type one. After rescuing his Childhood Crush Mizuki, he brings her to a small overlook where she awakens to see him, in Guyver form, and almost instantly manages to deduce who's behind that odd alien mask. (and bear in mind in Guyver form the guy is at least seven feet tall, not counting the horn on the head of the armor from all we can see) He stands up and looks into the sunset, then turns around, and walks off not saying a thing to her as she desperately screams/pleads for him to come back. The epilogue says Mizuki went back to school and was fine after that, but Sho himself is never seen again. Presumably he and Guyver III continue their war against Chronos in secret but nobody knows it.
- Tengen Toppa Gurren Lagann, with, of course, Simon in type two. Course, he's actually just leaving his more responsible friend in control of the government because he's a wandering hero type.

- Aya in Weiss Kreuz walks away from his beloved little sister and the girl who has a crush on him at the finale of the first series, after saving both of them from the Ancient Conspiracy and their Psychos For Hire, because it's the only way he can protect them from the life he leads as an assassin.
- Inverted with Ben Grimm/The Thing of the Fantastic Four. He constantly deals with the fear, rejection and scorn of the world at large because of his rocky exterior, however he actually found love after the transformation into the Thing with blind sculptress Alicia Masters. Though he is very protective of her, as a Super Villain's daughter her odds of an uneventful life are already low.
- Also, in at least a few stories, he's less likely to terrify passersby than he is to be mobbed by people wanting his autograph; being a member of one of Marvel's most prominent superhero teams for a couple decades does that to a person.
- Ben Grimm is often known as 'The Idol Of Millions', and is one of the most popular heroes in the Marvel Universe. His fear of rejection mostly stems from self-loathing due to his appearance, and early encounters before his fame took off.
- Batman - At the conclusion of Batman: Year One, Batman (who is unmasked) saves Jim Gordon's Baby. Jim Gordon has suspected Bruce Wayne of being Batman throughout the whole arc.

(Since Our Vampires Are Different, a person who has been turned doesn't become a full vampire until they feed for the first time. Until then, they're still themselves, and though the hunger is felt, they don't have to feed to survive.)
- Harry Potter himself attempts this with Ginny Weasley when he chooses to leave her to finish the job of destroying Voldemort, even doing the walk-away. However, Ginny is Genre Savvy enough to know what he's doing and why, and more or less pledges to wait until he's finished with what he needs to do.
- Stationery Voyagers runs the whole gamut with this.
- Inverted in that Arnold "Pextel" Rubblindo faces constant rejection from his mother over the fact that he was turned into a robot.
- Subverted to Hell when Pextel not only can't use it on Pinkella due to her being a core team member, but when it would do absolutely no good because she doesn't care if domestic partnership to a robot means perpetual virginity.
- Totally averted with Rhodney, Oceanoe, and Marlack.

Wanda finds that Cyan is holding onto the wedding ring, she realizes that somehow the "sad man" is her dead husband. Spawn watches Wanda's reaction from afar, and then executes a textbook example of turning away.
