- Damon Gant accuses Miles Edgeworth of this in Ace Attorney. He says that they both have the same hatred of crime, and that eventually, Edgeworth will cross the line just to seal away someone he knows is guilty. Edgeworth, thoroughly rattled, leaves the prosecutors' office and doesn't come back until he's certain he can prosecute a case and seek the truth, not just a Guilty verdict or another "win" for his record.
- Justice For All hints at this between Phoenix and Franziska von Karma. Acro, in the third case, remarks that the two are remarkably similar, that they both see the world through the same rose-colored glasses. Phoenix vilifies her for manipulating evidence in her favor, telling witnesses not to discuss things that don't make sense with her theories. However, Phoenix willingly defends a client he knows to be guilty, even accusing an innocent woman and using the evidence against her, albeit under threat of his friend Maya being killed.
- In Ace Attorney Investigations 2, Franziska comes to sympathize with Yumihiko after seeing how terribly his father treats him, and in the ending, expresses concern for him, as he will have to live up to his father just like she will have to live up to hers.
- This pops up a lot in Fate/stay night and the prequel Fate/Zero as well. To name just a few examples;
- Fate/Zero's Kiritsugu and Saber get along very badly despite being Master and Servant, and there is repeated emphasis on how much they're at odds because of their differences, but they are fundamentally very similar deep down; Kiritsugu is very much Saber's Shadow Archetype. Kotomine and Kirisugu subvert and then invert this; Kotomine initally thought Kiritsugu, who was an enemy master that has nothing in common with him at first glance, was the same type of person as him, but it turned out that he was his Foil in all respects.
- Fate/stay night, taking place ten years later, has the main character Shirou and Big Bad Kotomine again, playing it perfectly straight this time, and with the character in question being Shirou's Shadow Archetype / Evil Counterpart to boot. And, as if to complete the cycle, Saber and Shirou are this too. Although they get along for most of the series, there's conflict between them early on in the series which is caused by this.
- A few cases come up in Katawa Shoujo:
Hisao: Competitive until the last. Maybe Lilly and Shizune aren't so different, after all.
- Hisao notes that, like Hanako, he has allowed his disability to define him, preventing him from opening up to others or thinking about his future.
- Shizune and Lilly, may be at odds over how to run the Student Council, but at heart, Lilly is almost as competitive as Shizune. This is particularly evident in the fishing scene in Shizune's route, and when after they reconcile in Lilly's route, Shizune lightheartedly challenges Lilly to do better at her new school, a challenge Lilly accepts.
- Ikemen Sengoku has several cases:
- Nobunaga and Kennyo, despite being mortal enemies, have a surprising amount in common: both are called "demons" by others because of their ruthless killing of anyone who stands in the way of them achieving what they view as a greater cause, and both also believe themselves to be Necessarily Evil monsters unworthy of love.
- Hideyoshi and Mitsuhide, in spite of their otherwise polar opposite personalities, share the same unconditional devotion to Nobunaga and willingness to sacrifice their well-being to further his ambition.
- Shingen, despite loathing Nobunaga, turns out to have a lot in common with him on his route: like Nobunaga, he's a charismatic leader who has a surprising Sweet Tooth and is willing to resort to ruthless methods to achieve noble goals and makes a bet with the main character with the initial goal of making a game out of getting her to willingly submit to his advances until he realizes to his dismay that he's fallen hopelessly in love with her despite not believing himself to be deserving of her love. Chapter 10 of his route even has the main character deliberately "lose" their bet to demonstrate the depth of her feelings for him in a fashion similar to how she does it in Nobunaga's Ch 10.
- Kenshin's Romantic route has Kenshin himself acknowledge that he's not so different from Kennyo in how his hatred and desire for revenge threatened to consume the better, more moral side of him, and say that Kennyo might have been able to pull himself back from the path of destruction like he did if he had received the support and love of someone like the MC.
- In the H-Game Lucy Got Problems, Ellie mentions that the Angels caught wind of some Demons living in her home forest, so they dropped about a million pounds of holy fire on it. She states that it doesn't matter if the fire is infernal, mundane, or heavenly to anyone or anything caught in the middle, and the end result is always ashes.
