The first pair, for the sake of naming I will call Pair #1, wasn't exactly established. The alias was used once before the the New 52, but both the characters' identities are original.

Pair #2 uses a villain that was introduced before the New 52 and a completely unrelated new character. Hint: these guys actually share real names.
