Basic Trope: A character from game X makes a special guest appearance in game Y.
- Straight: Darrin and Stella from the Fighting Game Generic Fighter III appear as guest characters in Destiny Duel II.
- Exaggerated: The roster of Destiny Duel II consists of 30 characters, out of which only 5 characters are original, the rest are guest characters from Generic Fighter III (Again, Darrin and Stella), Cruisin' and Bruisin' in New York (Nico Forelli and Xian), and even non Fighting Games such as the Tales of Troperia series, which are all RPGs (featuring their classic Rival Final Boss Claidheamh), and Super Troper Land, a Mario-styled Platform Game, among others.
- Downplayed:
- Destiny Duel I - V never have had guest characters, and Darrin ocasionally appears as a background NPC, but finally, in Destiny Duel VI Darrin appears as the only guest character in a cast of 40 fighters.
- Darrin and Stella are referenced in costumes for some of playable casts in Destiny Duel II.
- Justified: Generic Fighter III and Destiny Duel II take place in the same universe (Or at least, developed by the same company), so, both games donating Guest Fighters to each other comes as no surprise.
- Inverted: Original Generation.
- Subverted:
- Fred from Destiny Duel I, appears in Destiny Duel II as a DLC character by popular demand. He doesn't have a prominent role, even a chapter in the Story Mode of the game. He just doesn't appear anywhere within the story. But he's not exactly a guest character because he's part of the world of the franchise after all.
- Charlie, The Hero of Destiny Duel II, discovers that Darrin is actually Rick in a Paper-Thin Disguise, thus exposing his cover-up.
- Double-Subverted: But then it is revealed that this Rick was only an illusion, and the real Darrin comes out of nowhere to challenge Charlie.
- Parodied: Darrin is a Creator Cameo, who paid a lot of money so the developers included him in Destiny Duel II, because he wanted them to make him a Badass... And he got what he asked for, they made him "Bad" and "Ass".
- Zig-Zagged: Even-numbered games of Destiny Duel (II, IV and VI) have guest characters from the Generic Fighter series, whereas odd-numbered ones (I, III and V) don't.
- Averted: No guest characters at all. The whole roster of "Destiny Duel II'' is original.
- Enforced: Darrin is an Ensemble Dark Horse, and the developers of Destiny Duel II want to keep appealing to the fanbase of the Generic Fighter series, even after its Grand Finale. The solution? Make Darrin appear in Destiny Duel II as a guest character.
- Lampshaded: "Who is this Darrin guy? I have never heard of him around here."
- Exploited: Knowing (read: blindly judging) that Darrin is a Naïve Newcomer, Sergey picks a fight with him, in hopes of an easy victory in his first turn.
- Invoked: The sponsors of the Destiny Duel II tournament send an invitation to Darrin from Generic Fighter III, as they've seem him in action. Darrin accepts.
- Defied:
- Darrin rejects the invitation.
- Alternatively, Destiny Duel II fans decide that they've had enough of Darrin. The developers take note of this, and for the sequel, they put Darrin on a bus.
- Another alternative: The idea of having Darrin as a Guest Character was on the paper, but it's discarded at the last moment.
- Discussed: "Darrin, you have been chosen to represent your region in the Destiny Duel tournament. Do you have what it takes?"
- Conversed: "Did you know that Darrin is going to appear as a Guest Fighter in the new Destiny Duel tournament?"
- Implied: Thanks to Laura, the other characters of Generic Fighter III learn that the rumor of Darrin being invited to the Destiny Duel tournament was true.
- Deconstructed:
- It's made clear that the rules and gameplay of Destiny Duel II are different from those of Generic Fighter III; because of this, when Darrin makes his guest appearance, he's at a very low level compared to the rest of the cast, and he gets demoted to Joke Character status, keeping fans from choosing him in Tournament Play.
- Alternatively, when Darrin makes his guest appearance, he's at a very high level compared to the other characters, so he becomes a Game-Breaker, gets banned from Tournament Play, gaining the hatred of his fans.
- Reconstructed:
- Darrin returns again as a guest character in Destiny Duel IV, where it's revealed that Darrin has been training and taking several levels in badass, appearing this time as a decent fighter, or at least, a Difficult, but Awesome Lethal Joke Character, regaining the love of his fans.
- Alternatively, Darrin returns again as a guest character in Destiny Duel IV, where it's revealed that he was slacking off, and did nothing to improve between games, whereas the other characters were training, and caught on with him. So, this time, he appears as a Mid-Tier, and regaining the love (Or hatred, depending of your interpretation) of his fans.
- Played For Laughs: Destiny Duel II is Lighter and Softer compared to Generic Fighter III, so, when an ultra badass stoic Darrin makes his guest apearance, he finds it hard to adapt to the campiness and silliness of this new setting, with hilarious results.
- Played For Drama:
- Destiny Duel II is Darker and Edgier and/or Bloodier and Gorier compared to Generic Fighter III, so, when a Badass Adorable Cute Bruiser Stella makes her guest appearance, she suffers a Heroic BSoD on her first day when seeing herself exposed to all that amount of darkness, tragedy and violence, losing almost all her optimism.
- Alternatively, Darrin is killed in Destiny Duel II, so, his son Darrin Jr. makes a guest appearance in Destiny Duel IV so he can find the one who killed his father and enact his revenge.
- Destiny Duel II is Lighter and Softer compared to Generic Fighter III, but also has lower overall power levels. Darrin thus shows up as an Outside-Context Problem whose brutality and might make him a nightmare to face.
