“All it takes is one bad day to reduce the sanest man alive to lunacy. That's how far the world is from where I am. Just one bad day. You had a bad day once. Am I right? I know I am. I can tell.

The Joker is one of the main playable characters of a crossover between Lego Batman (hence the title) and Lego Marvel. He is one of the supervillains led by Lex Luthor to take down Hydra - Luthor not wanting to be outclassed by Baron Zemo. This group ends up teaming up with the main heroes - consisting of the founding members of the Justice League, Robin Tim Drake (who's also part of the League), several of the Avengers, Spider-Man, Wolverine, the Thing, and Deadpool - for the final battle against Zemo.
