Barbara Gordon as Batgirl really stole the hearts of fans. There are whole tribes of fans that can see the mantle with no one else, and this guy probably creates a few more, every time he walks down the street. Batman is a tattoo no one wants to mess with, and that's exactly how the Dark Knight should be! Look at how well those colours have come out - that's Skin Art Masterclass right there.
Catwoman the first of two back tattoos, is based off promo art for the video game Mortal Kombat vs DC Universe.
A twist on the feline's popular purple dress mixed with her modern combat look - and enough 'cats eyes' to lose yourself in - means one massively effective tattoo.
Finally, what is Batman without The Joker? In what seems like a nod to Brian Bolland's Joker in Batman: The Last Laugh, with the styles of Mike Deodato Jr added in, if I was going to ask any guy to take his shirt off, it would be this dude right here.
As far as back tattoos go, this is stunning stuff.
