3 Jokers 1

You know...when DC Rebirth began...Batman was in the mobius chair and it revealed that there are three jokers. It was a surprise twist, and its still one of the mysteries in the DCU That still needs to be resolved. But...surprisingly enough...The three jokers thing...it also works for every animated BATMAN Shows since the DCAU Batman. 
In Batman the animated series, we had the joker voiced by Mark Hamill. This Joker was inspired by the bronze age joker, and jack Nicholson's portrayal. one thing about this joker is that he also had the real name "Jack Napier" And he was a hitman for the Valestra Mob. 

in the new Batman adventures. The joker was back, but..he looked different. Completely Black eyes, and no red lips, he had a different suit and was a bit skinnier. Aside from that...he was very similar to the joker from TAS...except for two things. Here...he had no real name. Nobody knows who he was, while in the animated series they knew that Joker's real name was Jack Napier. And in the episode joker's millions, when the joker gets a huge fortune in money..he completely retires from crime altogether. He doesn't even want to fight batman anymore. Does that sounds like the same joker from TAS? the Joker that said "Without Batman...crime has no punchline.." 

Then...in Justice League and Batman beyond...the joker had gone through yet again a new redesign..Here he was less skinny then how he was in The New Batman adventures. He wore the same suit as "The New Batman adventures" but he had very dark red lips, and his eyes looked more normal, and wasn't completely black anymore. But...this joker here...he had no ties to the mob anymore. It was never mentioned again. and in the movie Batman beyond: Return of the joker, this joker took over Tim Drake's body, so you can say he literally became a new person. 

See? Three Joker designs. each a little different from one another. THREE Jokers.
