Bill Cipher

"Oh! Hey, Mickey! How do you like my new...Firebird? Yep, straight from Fantasia 2000! Anyway, have fun! Muhahahahahahaha!"-Bill Cipher, Epic Mickey 3: Eye of the Storm, First Boss: Firebird.

History
Bill first appears in Gravity Falls. He then threatens to destroy multiple worlds, so Dr. Doofenshmirtz builds a machine to summon bad guys to stop him. After his defeat, Bill breaks the fourth wall and hides out at Disney World while the events of Kingdom Keepers go on. Years later, he comes out to destroy and corrupt Disney's long-loved world, but is stopped by Yen Sid with the power of the Painter's Blade, the paintbrush used by him and Mickey. Bill is banished to Wasteland, but not before becoming a half-Blot by spilling Magic Paint and Thinner on himself. This then triggers the events of Epic Mickey 3: Eye of the Storm as he tries to take over Cartoon Wasteland. He is thinned out by Mickey, but returns in Epic Mickey 4: Fate of Three Worlds as a optional boss. Later Blot Bill (Bill Cipher's Wasteland nickname) returns in Kingdom Hearts vs. Mortal Kombat as Shao Khan's assistant and secondary antagonist.

Becoming the Boogieman
As we all know, Bill becomes the Oogie Boogie, the alter-ego of Dr. Facilier, (What do you think his shadow is?) and becomes the Nightmare King, with the Headless Horseman and the Firebird at his fingertips, and an army of Dream Hipsters waiting. As you can see, many defeats bring you a long way.
