It's based on amazing Phil Bourassa's work on Young Justice [link]
And Rymslim ([link]
made me want to do kind of the same thing with Batman.
So, for fun, I used Young Justice Batman and Nightwing to recreate some of the most famous Batmen (past bat-suit or else worlds batmen).
I used a lot of artists' work to make them. For exemple, the Cavern Batmen's head is almost completely based (lets say copied) on Chris Sprouse's drawings.
From left to right, downward : Vampire Batman, Bruce Wayne wearing Batman Beyond's suit, Justice Lord Batman, two different designs for a Sinestro Corps Batman, Dark Knight Returns Batman (two versions), an old Elseworld Green Lantern Batman, Batman from Gotham by Gaslight.
Soviet Batman (from Superman Red Son), Flashpoint Batman and an unmasked Thomas Wayne, Terry McGinnis from Batman Beyond, Damian Wayne as Batman (Batman #666) masked and unmasked, Adam West's Batman and Nolanverse Batman,
The first Batman, 70's Batman, Batman Animated, Classic Batman, PHIL BOURASSA's Batman and Bruce Wayne, Green Lantern Batman, Zur-En-Arrh Batman, Black Lantern Batman, Batman Incorporated, DC new Universe Batman.
Cavern Batman, Azrael Batman, Jason Todd, Tim Drake & Richard Grayson as Batman.
It's for fun only.
Batman belong to DC Comics. Original design were made by Phil Bourassa !
