Are there any dc marvel crossover stories involving secret identities?

The verified sources do not mention any crossover event between the DC and Marvel universes that centers on characters with secret identities. While both franchises have produced numerous crossover comics and multiverse stories, none of the documented crossovers explicitly involve the concealment or revelation of a character’s alter ego. Without supporting citations of such a storyline, it is not possible to affirm the existence of a DC‑Marvel crossover featuring secret identities. Fans may encounter fan‑made or speculative discussions, but these are not substantiated by the provided sources. If a new crossover were announced or released, it would need to be corroborated by official publications or reputable databases before being recognized as part of the canon.
