For the people who watched Suicide Squad and are looking for Joker/Harley stories here we have a list of recommended comics.

The characters have many different designs in different stories.

>Batman confidential (issues 7-12): Madmen and Lovers
>Arkham City (2011): Comic by Paul Dini, it’s not the comic called Arkham Unhinged
>Gotham Adventures #10 and #14 (part1 and 2)
>Batman The White Knight (focus on them completely, recent)
>Batman The dark prince charming (recent, if you like SS you want this one)
>Gotham City Sirens vol1 issues #3, 4 and 5 though the vol is good
>Harley Quinn (2000-2004) #32 : This one isn’t the comic called Harley Quinn nowadays.
>Batman Adventures #3 (2003-2004, there’re 2 series with the name batman adventures) “my boyfriend’s back”
>Batman Adventures #16 (2003) : “A wedding to die for”
>Joker/Mask
>Harley loves Joker: Recent series of mini stories by Paul Dini in the last pages of Harley Quinn (2016-) issues #17-25

Just funny things with them together, kisses here and there.

>Gotham Knights #14: Has a short story in the last pages, very recommended
>Batman and Robin Adventures #18
>The Batman Adventures #28 (1992-1995)
>Justice League Unlimited #41

The art was a little ugly cause they’re old but those were very good for our intended purposes

>The code: Batman #570 (part1), Detective comics #737 (part2)
>Batman #663 by Morrison: the art is ugly and the story is strange but Harley was the incarnation of Joker’s humanity in this one.
>Joker: last laugh: issues #3 and 5, though you should read the rest to know what’s happening.Mini with 6 issues
