Recognized
is a Danny Phantom and Young Justice (2010) crossover where Danny is accidentally Zeta-beamed to the Cave... using Robin's credentials. A now complete sidestory called The Theorists deals with Wes Weston and Marvin meeting and sharing their theories.
The author has also written an unrelated Danny Phantom and Spider-Man: Homecoming crossover named Fire With Fire, which is ongoing.
Tropes:
- Blackmail: Danny and Robin use the footage of Lex shooting Danny from a body-cam to blackmail Lex.
- Book Ends: The story both begins and ends with someone entering the Cave via someone else's Zeta Beam ID, Danny at the start and Wes at the end.
- Canon Welding: Vlad has connections to Cadmus and the Light, mainly through Lex Luthor, which is where he got the technology to make Dani.
- Here We Go Again!: At the end of the story, Wes Weston manages to follow Danny and Robin through to Mount Justice because the Zeta Tube thought that he was Wally, the implication being that he's the clone of Kid Flash from Cadmus who was supposedly destroyed by Match.
- Hoist by His Own Petard: Lex Luthor tries to kill Danny with an anti-ghost weapon, but he survives, and because of that the body cam for the Robin suit he was wearing now has footage of Lex trying to kill a teenager.
- Hollywood Hacking: Tucker is the only person to have found the decoy Bat-Server.
- Identical Stranger: Danny being identical to Robin, even to the point of the Zeta Tube network mistaking him for Robin, is the major catalyst that gets the story going. They turn out to be twins Switched at Birth.
- Incredibly Lame Pun: When Danny gets his own Zeta Tube designation, it's B-00, or "boo", which Danny is not impressed by.
- Mix-and-Match Critters: The story starts with Danny fighting a winged ghost gorilla.
- Rewatch Bonus: Once it's revealed that Robin was replaced with a clone at Axiom Labs, everything from him waking up without a cut on his forehead on is taken in a whole new context.
- Sequel Hook: Besides the hints at the canonical arrival of the Reach, the last chapter of the story has Wes Weston follow Danny and Robin through the Zeta Tube to Mount Justice under Wally's designation, the implication being that he's the Kid Flash clone Match supposedly destroyed.
- Stable Time Loop: Clockwork sends Dani back in time to initiate the Swapped At Birth situation with the Grayson and Fenton sons, not just to preserve her own existence, but also to make sure that Danny Phantom and Robin come into being, in order to ensure that humanity survives, among other things, the Disasteroid and the Reach invasion.
- Switched at Birth: Thanks to a time-travelling Dani and Vlad, the real Danny Fenton was swapped with one of the Grayson twins... and the twins themselves were swapped around so that Danny is technically Richard Grayson and Robin is technically James.
