==Villains Unite!==
Bill Cipher appears as the main antagonist of Villains Unite!. Having been imprisoned in an interdimensional cell by Dr. Doofenshmirtz and his alliance of villains, Bill Cipher impersonates Major Monogram to manipulate the protagonists into freeing him. After the player reaches his cell, Bill Cipher reveals himself and attacks them.
===Boss Fight===
Bill starts the battle by creating a row of acid pools between him and the player above which a row of barrels spawn. His main attack is to fire a laser the length of the arena from his eye, which he sweeps in an arc in front of him. After doing this a couple of times, he will teleport into the main part of the arena, and drop red sparks, before teleporting to another part of the arena. He does this five times before teleporting back behind the wall of barrels, after which all the sparks will explode.
He has a purple forcefield during his attacks, so he can only be damaged while he is moving in-between each attack. The barrels he spawns before fighting also block your attacks, so until a hole is created he can only be hit for a brief moment after placing a spark.
Once his health has been reduced under a third, he will enter his second phase; his body turning red and the colour of his features inverting. The acid will disappear, and he will begin chasing after the player, trying to deal collision damage. Should the player run underneath Bill, he will fire a laser in the same way as in the first phase, having the purple forcefield while firing it.
When his health is nearly depleted he will teleport to the four corners of the arena and fire a shorter laser in a longer arc. Enemies will also exit the gates around the room and begin chasing the player. Once Bill has fired a laser in each corner, he will return to chasing the player until he is defeated.
==Gravity Falls: Take Back the Falls==
Bill Cipher appears as the main antagonist of Gravity Falls: Take Back the Falls. In a cutscene before Level 12, Bill captures the player characters and exchanges them for access to Ford's mind. He is pursued inside the mindscape by Dipper and Mabel, who battle him.
===Boss Fight===
Bill Cipher is fought as the game's final boss in Level 12, set inside Stan's mindscape. Bill teleports around the arena, using one of several attacks:
*Bill creates seven blue fireballs that revolve around his body for a few seconds. He then moves back and forth for several seconds, trying to ram into the player, before firing the fireballs out around him. He will then be vulnerable for a few seconds before teleporting away. He surrounds himself with an two additional blue fireballs with each third of health lost, and his movement speed increases.
*Bill summons four screaming heads that drop from the top of the screen, and harm the player on contact. Bill will be vulnerable for a few seconds, after which he will teleport away and the heads will erupt into blue pillars of flame. An additional two heads are summoned after each third of health is depleted.
*Bill teleports several more times, before creating an explosion around himself.
*After Bill has under a third of health remaining, he can teleport next to the player and attempt to poke them. If he is successful, they will be transformed into a gold statue, which he uses as a backscratcher before tipping his hat to them as they turn back to normal. Bill repeats this several times.
Bill will rarely forcibly interrupt combos by turning black and drawing energy into himself, which knocks back the player if they are attacking him.
If the player runs out of lives. Bill Cipher begins dancing before the game over screen appears.
If the player successfully depletes his health, the other player character appears behind them as the mindscape begins to shrink. Bill creates a massive explosion around himself that knocks out both Dipper and Mabel, and he begins dancing. Grunkle Stan then appears and Bill begins to panic as Dipper and Mabel are teleported away. Stan punches Bill in the eye, destroying him as the mindscape continues to shrink until Stan is engulfed in blue flames.
