"I hate you, Joker."
"I hate you too."
— Batman and The Joker
Lego Batman is, among other things, a Romantic Comedy about Batman and The Joker. No, seriously.
- The conflict starts because Batman won't admit that The Joker is his "best enemy".
- The Joker: Okay, look, I-I'm fine with you fighting other people if you wanna do that, but what we have is special. So when people ask you who's your number one bad guy, you say...Batman: Superman.The Joker: Are you seriously saying that there's nothing, nothing special about our relationship?!Batman: Whoa! Let me tell you something, J-Bird. Batman doesn't do ships.Joker: What?Batman: As in relationships. There is no us. Batman and Joker are not a thing.
- When The Joker turns himself in, he tells Batman he won't be able to "fight any of this anymore", while rubbing his hands down his body.
- Harley Quinn tells The Joker that if Batman doesn't appreciate him, he needs to move on.
- Not to mention the Phantom Zone villains root for him to move on and the Daleks even shout "He's not worth it!"
- The Joker: "Do you realize that you have never once said the words, "I hate you, Joker"?"
- The Joker tells Batman he refuses to stay in a "one sided relationship".
- Batman: “You’re the reason that I get up at 4:00 in the afternoon and pump iron until my chest is positively sick. You’re the reason I’ve given up a life spent with Russian ballerinas and lady active-wear models. And if it wasn’t for you, I never would have learned how connected I am with all these people, and you. So if you help me save Gotham, you'll help me save us."
- At the end, they tell each other how much they... "hate"... each other.
- For most of the movie, Dick Grayson is deluded into thinking that he has two dads; Bruce Wayne and Batman.
