- In the Book 2 premiere, Korra hasn't had a good opinion of her father Tonraq since she learned he was one of the people behind the compound (Tenzin had a hand in that too) along with his exile from the Northern Water Tribe, and the fact he is treating her like a child. But later on, Korra swears off loyalty to Unalaq once it's revealed he not only fixed her father's trial to send Tonraq to prison and also to appear "merciful", but also caused Tonraq to be banished so that he could become chief of the Northern Water Tribe.

- In Avengers, Assemble!, Spider-Man suffers this towards Captain America when the latter quits and forms his own team after Ultron made fools of everyone.
- Batman: The Animated Series does this to some extent in "Beware the Gray Ghost". The eponymous character (voiced by Adam West) was the hero of an in-universe TV show that Bruce Wayne loved as a child, and an inspiration to the latter's own vigilantism. The actor, although not mean, is a bitter old man who has suffered from longterm unemployment, and briefly grows to hate his old role. Batman is quite disappointed when this Reality Ensues, but once it turns out that rediscovering the past is vital to solving a crime, the actor fortunately rediscovers his passion, aids Batman on his quest, and the episode ends on a very high note.
- Bob's Burgers has "Torpedo", where Bob meets a baseball player he's always been a fan of, though everyone keeps pointing out that it's a little weird that his hero is the same age as him.

Throughout the episode, Bravestarr often tells Jingles "You were my hero..." in a mournful tone of voice. Upon Jingle's arrest, he attempts to understand why his idol attempted to kill him (you see, it was a test of his ruthlessness to join Tex Hex's gang), only for Morgan to show how far he has fallen from the beloved Jerk with a Heart of Gold Bravestarr remembers by saying "I never asked to be your 'hero'". After he's taken away, Bravestarr tells his deputy (who looks up to him) that "If anyone ever, ever lets you down, just... remember them for what they did right, and not what they did wrong."

- Codename: Kids Next Door:
- Cree was formerly Numbuh Five's mentor, her Cool Big Sis (literally and figuratively) and one of the best operatives of all time. As you might expect, then, the fact that she turned traitor made her one of the worst examples of this trope, becoming the Cain to Numbuh Five's Abel in the process. To make it worse, if Operation: M.A.U.R.I.C.E. is any indication, Cree seems more than willing to reconcile with her sister, but only on her terms; she seemed overjoyed when Abby briefly seemed to be willing to join her. Fortunately, Abby's other idol convinced her otherwise.
- A strange example would have to be Chad Dickson, f.k.a. Numbuh 274 and Soopreme Leader of the KND. Both his debut and his final appearance had shown him to be downright idolized by his subordinates (he had trading cards, for God's sake), making his betrayal downright heartbreaking in hindsight. Numbuh 1 deftly points this out in their final confrontation, having been one of the ones most affected by this betrayal as Chad was both a mentor and a dear friend to him, only for his former comrade to shout that he doesn't care. While Chad being a teen spy like Maurice has somewhat redeemed him, Nigel's forlorn expression at the end of the episode expresses how that doesn't detract from his legitimate negative qualities or what happened between them.

- In the DuckTales (1987) episode "Where No Duck Has Gone Before", Huey, Dewey, Louie, and Doofus idol worship Major Courage, hero of the TV show Courage of the Cosmos.

When they realize that they have really been launched into outer space and real aliens have captured them, Courage panics, and the boys see what a coward he really is ("real heroes just do their jobs!").Courage: What happened?

He sent Spitfire away with a fake note that her mother was sick and framed Rainbow Dash by cutting off some of her hair and planting it. Why? Because he was afraid Rainbow Dash would break his flight record, and with her out of the way, his record would be totally secure. If lying and screwing around with Spitfire's personal life in order to sabotage Rainbow Dash's future for such a petty and selfish reason wasn't bad enough, Wind Rider is also revealed to be an extremely narcissistic Smug Super who self-admits he isn't above playing dirty to get ahead, even if it means screwing over his teammates.

Millennia ago, they were both heroic until Orion Pax's becoming Optimus Prime caused Megatronus' jealousy to lead him to becoming the villainous Megatron. When Optimus loses his memory, Megatron quickly resumes the master-pupil relationship for as long as he can until Orion starts figuring out that Megatronus isn't quite as noble as he remembers.
- The Venture Bros.:
- Brock Samson's mentor Colonel Hunter Gathers is thought to have gone rogue and Brock is sent on a mission to hunt him down and kill him. Brock is disgusted to find that his mentor, who insisted on never killing women or children, apparently killed the woman he'd slept with the night before (she turns out not to be dead, but Brock doesn't know that). In the end, we see that his mentor ran off to get a perfectly innocent sex change, and the morals he passed down to Brock invalidated the now-female mentor as a target. Though as it turns out in season 4, he really did go rogue... but he wanted to do things his own way rather than following OSI's strict policies. And with the Season 4 finale, it appears that Colonel Gathers is the new commander of OSI, letting him come full circle.
- Season 3 showed flashbacks where Dr. Jonas Venture Sr. was either a complete Jerkass or just too naïve to realize the damage he was inflicting on his son due to his womanizing and seeming disregard for human life.
- Whatever pedestal Jonas Venture Sr. had left was broken, crushed, and pulverized into dust by the season seven episode "Arrears in Science."
- Inverted in the Wander over Yonder episode "The Good Bad Guy" when Big Bad Lord Hater finally gets to meet his inspiration and idol: Major Threat. Unfortunately for Hater, the once ruthless tyrant has become a hippie who would rather go by Jeff, and this change of heart was caused by Hater's arch-enemy: Wander! So Jeff still falls under this category in a Bad is Good and Good is Bad kind of way.
