Zmey Gorynych (Three Heroes) vs Batman (DC Comics)
Zmey Gorynych (Three Heroes)
Batman (DC Comics)
Please let me know if I used the wrong image or tags for either character! I do my best, but I'm not in every fandom.
Propaganda for Zmey Gorynych:
Being a three-headed dragon, the boys are canonically mentioned to be plural by their best friend Dobrynya in their debut movie (Dobrynya Nikitich and Zmey Gorynych). They don't have designated roles, but the left head is often seen as the youngest in the crew (mentally), while the right head is the protector, often standing up for others or his mates when they get hurt. That leaves the center, who's the quiet (mostly) and very sensitive presumed host. One things for sure: he's the collective's CNS and pain holder (spoiler alert!).
Propaganda for Batman:
When Wonderwoman uses the lasso of truth on him, he says his name is "Batman". While this is often read as 'oh, Batman is the real person, Bruce is the mask' I think it could also very easily be interpreted as a separate person altogether. Bruce is the dad and the microcelebrity and Bats is the vigilante. Also the Lego Batman movie with the whole bit where Bruce and Bats are co-parenting Robin. ALSO Zur-En-Arrh was remade to be an alter of Bats in one of the comic series so it's canon in that universe.
