Bill Cipher

**Bill Cipher** is a crossover boss. He is fought in "Weirdmageddon Waltz". He is fought on land in all phases, except for the fourth phase (which makes the player use a plane).

## Description

### Appearance

Bill Cipher is a triangular dream demon with yellow skin, brick lines on the lower half of his body, a single eye in the middle of his face, visible eyelashes, white sclera, and a black pupil that is either shaped like an oval or a slit. He has thin black arms and legs, and he has four fingers on each hand, while his feet do not have toes on them. He wears a black tophat that floats slightly above his non-discernible head (so he's technically not actually wearing it), and a black bowtie on his brick lines. He also has an tan-and-white glowing effect on his body, and he hovers above the ground (since he's capable of flight). His body glows when he speaks, due to him not having a mouth.

When he is in his angry form, his skin turns red, his sclera turns black, and his pupil turns white. His outline, limbs, and accessories are also white. He has a dark red glowing effect on his body.

When he possesses Dipper (while using the alias of "Bipper", courtesy of Mabel), he wears a black reverend outfit that is reminiscent of his default form's "gentleman aesthetic". Bipper's sclerae is yellow, his pupils are shaped like slits, his skin is extremely pale, and his eyes slightly glow. He also wears brown shoes.

During his fourth phase, there are some minor differences between the two variants of his default form. Unlike his default form in the first phase, this one has white brick lines (instead of yellowish-beige), and his glowing effect moves when he speaks (instead of his body glowing). Other than that, his appearance in his first and fourth phases are nearly-identical.

Bill's final form is complete body horror. His final form has a massive resemblance to a spider. He is depicted as a giant red pyramid with a black shading effect on the bottommost tier, four eyes with each one on all four sides of his non-discernible head, and black sclerae. He has eight glowing yellow arms, with a pair of them acting as legs, and another pair of those arms emerging from his bottommost mouth-like growth. Both of his mouth-like growths have a pitch black interior, yellow razor sharp teeth, three black tongues in both of the growths, and they're located on his body (instead of his face). He also has glowing yellow slit-shaped pupils, and he can retract his legs to give him a more spider-esque appearance. He wears a glowing yellow recolor of his tophat and bowtie. His tie is located on his middle tier, and his brick lines are still visible. There is no visual indicator of him speaking, as his body does not glow and his mouth-like growths do not move to articulate his speech (as they do not count as actual mouths, despite looking like them).

At the very end of his Regular and Expert Mode knockout (right before the screen fades to black, while the player waits to see their results), Bill Cipher dies, and he is turned into a gray statue with his hand being held out (while his other arm is absent). Only one layer of his brick lines is visible as a statue, and his tie is missing. There's an abundance of moss and vegetation covering small portions of Bill's statue, due to it being placed in the woods. His statue also represents his boss level in the overworld.

### Personality

Bill Cipher's personality is about the same as the personality that he had in *Gravity Falls*.

## Battle

### Intro

Bill teleports into the mindscape, as the background becomes greyscale, and the background's animation is paused. He grabs his cane, and tips his hat to the player. He also says "Welcome to the mindscape, kid(s)!", as his dialogue overlaps with the announcer's speech before the fight begins.

### Phase 1

"Well, well, well! Someone's looking desperate!"

—Bill Cipher, Phase 1 Death Screen

Bill levitates on the right side of the area, while the player(s) stand on a large platform. Bill has four attacks in this phase.

* **Deadly Deals** - Bill's body is surrounded in a large blue flame, and he puts his hands up. Then a barrage of blue deal-making flames are lobbed at the player in three directions: arch, straightforward, and downwards-diagonal. Some of these flames might disappear from off-screen, then come back to attack the player from behind later. Some of these deal-making flames can be parried.
* **Hat's Off to You!** - Bill takes off his tophat, which rotates the screen. When the screen is rotated, the player could be pushed back into a deal-making flame or taking fall damage from sliding off of the platform, similar to Croaks' wind when he turns into a fan. The screen being rotated is only for a brief moment, as it will go back to normal, when Bill puts his hat back on.
* **Traumatic Teeth** - Bill chuckles mischievously, before he throws a bunch of deer teeth into the air. Then the teeth rain down on the platform that the player is standing on, and a small opening in-between the scattered deer teeth allows them to remain unharmed by this attack, similar to Pirouletta's roulette balls.
* **Classic Cane** - Bill Cipher has a ranged attack, where he attempts to jab at the player with his cane, if they're close to him. Staying far away from him is recommended to prevent him from using this attack.

After taking enough damage, Bill teleports to the other side of the battlefield, where the player(s) are standing. His eye twitches, before he finally snaps as his reaction towards the player outlasting him. Then he turns into his angry form, and a fire ring surround the area where the player is standing. A larger platform based on a stone carving of Stan's head is risen up into space, within the mindscape. Bill Cipher grows to a massive size, thus increasing his hitbox. Lightning briefly surrounds Bill's body, as it's emerged from his hands, while the player(s) reuse their scared animations from losing a level in the Mausoleums and at the beginning of The Devil's intro. Then the second phase commences.

### Phase 2

"Do you have any idea what it's like... WHEN. I'M. MAD?!?!"

—Bill Cipher, Phase 2 Death Screen

Bill Cipher and the player(s) are now on the opposite sides of the screen in his second phase. The player has more room to move around, now that the platform is bigger. Bill has three attacks in this phase, and he also summons an enemy.

* **Laser Cannon** - Bill's eye extends, as it turns into a black laser cannon. The direction of the laser always faces downwards-diagonal. The player can either duck under the laser to avoid it, or to fire an EX move at Bill's eye to stun him for a few seconds, while smoke comes off of his eye, and he's groaning in pain. Briefly immobilizing Bill with an EX move prevents the laser from moving any further, as he stops using the laser cannon, the moment he takes damage from the EX move.
* **Flames of Rage** - Bill Cipher uses his pyrokinesis to unleash a swarm of flame projectiles at the player. Some of these flames can be parried.
* **Nightmare Laser** - Bill points at the player, before a red-and-white laser (that is capable of making people's worst nightmares come to life) is shot out of his finger. If the player gets hit by the laser, the screen will glitch and the color aberration will briefly increase, similar to Cagney Carnation's pollen projectiles in his final phase. Every other laser can be parried.
* **British Dog Man** - This enemy is occasionally summoned by Bill to compensate for his lack of close-range attacks in his second phase. The British Dog Man will poke at the player with his cane, if they're too close to him. If the player is far away from the British Dog Man, then he will not attempt to attack them and will ignore them. He doesn't have a lot of hitpoints, so he can be quickly destroyed. Bill doesn't summon British Dog Men very often, so it's only a minor nuisance to the player(s) attempting to bypass Bill Cipher's other attacks.

After taking enough damage, Bill reverts back to his default form, and he shrinks down to his regular size. He snaps his fingers, which takes himself and the player(s) to a theater setting. The stage is briefly greyscale, before it gains its colors back, when Bill Cipher possesses Dipper Pines, and becomes "Bipper". Bipper laughs maniacally, while Mabel Pines is worried about the player's safety in the background of this phase. The third phase begins.

### Phase 3

"You can't stop me! I'm a being of pure energy with no weakness!"

—Bipper, Phase 3 Death Screen

Bipper is on the right side of screen, and he can actually move in this phase, so the player(s) have to dodge one of his attacks that makes him move to the other side of the stage. Bipper has three attacks in this phase.

* **Utilized Utensils** - Bipper thinks pain is hilarious, to the point where he has stabbed himself in the arms with forks and knives. Bipper pulls up his sleeve, before a bunch of utensils are launched at the player(s) in a spread formation, similar to Werner Werman's scrap attack. Some of the knives and forks can be parried, and there may be two parry-able utensils right above and below each other, so the player might get a chance to parry both of them at once.
* **Rush Attack** - Bipper runs as fast as he can towards the player(s), so he can change positions to attack from the opposite side of the screen, similar to Werner Werman's charge attack. The player has to jump and dash over him (or dash through him, if the Smoke Bomb is equipped) to avoid taking damage, since there aren't any parry-able objects that could be used to assistance the player towards gaining a higher jump height to bypass Bipper.
* **Slamming Shockwave** - Bipper slams his foot on the floor, which releases a massive shockwave that prevents the player's straight-shooting weapons from passing through it for a few seconds, similar to Dr. Kahl's Robot's laser in his first phase. The Chaser and Charge are unaffected by the shockwave, so they can be used to damage Bipper.

After taking enough damage, Bipper is exhausted, while he's sweating, his hair is unkempt, and his eyelids darken in color. Bipper passes out, before the background turns greyscale again. Bill flies out of Dipper's body, before Dipper's mindscape ghost enters his passed-out human body to become mortal again. Bill announces that the world will be his, as Mabel and Dipper are terrified. The twins quickly leave, before Bill gains a corporeal form, and Weirdmageddon begins. The player is forced to use a plane for the the fourth phase, as it commences.

In Simple Mode, the battle just ends with Bill flying out of Dipper's body, and he ends up flying off-screen, as Weirdmageddon never occurs.

### Phase 4

"Welcome one and all to Weirdmageddon!"

—Bill Cipher, Phase 4 Death Screen

The player flies a plane during the fourth phase, due to the fire obscuring the ground, and they would be unable to walk on it. Bill Cipher hovers on the right side of the screen, and he has three attacks in this phase. He also summons a few enemies. This phase is not available in Simple Mode.

* **Here Comes the Giant Fist!** - One of Bill's hands enlarges in size, as he is about to slam his fist at the player. When he is about to use this attack for the first time, it is identified by Bill briefly straightening his tie, before slamming his fist on the ground. This brief animation is no longer seen, if he decides to use this attack again. When Bill slams his fist, several triangular wood chips are sent out in a spread formation from the bottom of the screen. Some of these wood chips can be parried.
* **Laser of Vaporization** - Bill points at the player with an angry expression on his eye, before he fires a massive turquoise laser beam in the middle of the screen, hoping to vaporize them. The laser is not fired at the top or the bottom of the screen, similar to Grim Matchstick's blowtorch in his final phase, so the player needs to be on either untargeted portion of the screen to avoid getting hit by the laser.
* **Weirdness Bubbles** - Bill Cipher raises his hands in the air, as multiple weirdness bubbles float up from the bottom of the screen. If the player flies into a weirdness bubble, they will be teleported out of another one. However, the player might get teleported too close to Bill (so they would take damage on contact from him), or into a projectile that was spawned. It is best to avoid flying into the weirdness bubbles at all costs.
* **Eye-Bats** - Flying eyeballs with yellow irises and reddish-black bat wings. The Eye-Bats create a pinkish-red tractor beam from their eye, and the player will be turned into stone for a few seconds if they get into contact with the beam, similar to Cala Maria. Eye-Bats with pink irises can be parried. The Eye-Bats are very frail, so they can be quickly destroyed.
* **Water Tower Monster** - Bill laughs maniacally, as the ground is seen shaking abruptly, before a giant Water Tower Monster walks across the screen from the left side. The player can't get hit by the Water Tower Monster's legs, but they will be damaged if they fly towards its head. It can only be attacked, if it's shot at its head.

After taking enough damage, Bill teleports himself and the player(s) inside the Fearamid, as they return to normal ground and they no longer fly their planes. Bill sits down on his throne made of petrified humans in the background, before an arrow with the word "GO!" is located on the left side of the screen, where the player is. Then a dark amount of glowing eyes spawn on the right side of the screen, and the player(s) will take damage if they touch them. The numerous eyes disappear, when the player follows the arrow to start the next phase. Bill notices that the player(s) are getting away from him, so he turns into his final form and pursues them, as the fifth phase commences.

### Phase 5

"I GOT MY HANDS ON YOU, AND I DISASSEMBLED YOUR MOLECULES!!!"

—Bill Cipher, Phase 5 Death Screen

The player is back on land, during this phase. Bill Cipher chases the player(s) throughout the Fearamid, as the background moves, similar to Baroness Von Bon Bon's final phase. There are three brick-shaped platforms that the player can stand on, with one of them being a bit higher up than the other two. Bill Cipher has two attacks in this phase, but he gains a few more later on. This phase is not available in Simple Mode.

* **Sinister Swat** - Bill uses his multiple limbs to swat at the player. Since the hitbox of his arms are quite big, it's hard to not take damage from this attack. He can also extend his limbs to the left side of the screen to use this attack against the player(s) from there.
* **Bashing Bricks** - Bill punches a large hole in the wall of the Fearamid, as the background briefly stops moving when he does this. A ricochet effect lasts for the entirety of this attack's duration, until it ends. Multiple bricks from the Fearamid fall to the ground from the top of the screen, starting on the right side (where Bill is at), and ending on the left side (where the player(s) are). Some of the bricks can be parried.

Bill can only be damaged in this phase, by shooting his eye, as shooting at his body does *nothing.* The platforms can be used to get a better aim at his eyeball to properly hit him. After taking enough damage, Bill growls in aggravation, before he starts to move a bit faster throughout the Fearamid, so the player(s) need to be more cautious this time. Bill Cipher gains two more attacks, while he keeps his Sinister Swat and Bashing Bricks attacks, prior to this damage threshold.

* **In My Grasp** - Bill briefly stops moving (so does the background), before he attempts to grab the player(s) by putting two of his final form's hands out, so he could capture them. He can only use this attack, if the player is right in front of his face, while they're not standing on any platforms. The player needs to jump and dash towards the opposite direction to avoid this attack, due to Bill's enormous hitbox. If Bill Cipher fails to capture either of the player(s), he groans in annoyance, before he continues chasing them.

* **Dark Fire** - One of Bill's final form's mouth-like growths extends, before dark purplish-black fire is released from the growth. Either the top growth or the bottom growth can unleash this attack. If the player gets hit by the fire, the screen will darken for a few seconds. The stream of dark fire that Bill sends out from his mouth-like growths is pretty long, so the player(s) should keep their distance from him, if he's going to use this attack.

After taking enough damage, Bill Cipher reverts back to his default form, and teleports away. From off-screen, he can be heard yelling "NO, NO, NO, NO, NO!!!" in frustration. The background changes to Stan's mind, while it's burning up in blue flames, due to Ford using the memory gun to erase Bill's existence. Bill teleports into the damaged mindscape, and he's terrified of his eventual fate. The sixth and final phase ensues.

### Final Phase

"This isn't the last you'll see of me, Cuphead/Mugman! I'll be back!"

—Bill Cipher, Final Phase Death Screen

*(single player only, depending on who the player is using)*

"Neither of you can defeat me, even when I'm on the verge of DEATH!"

—Bill Cipher, Final Phase Death Screen

*(multiplayer only)*

Much like the third phase, Bill is capable of moving across the screen, but he is on the left side of the screen by default. The player(s) have a lot of room to move in this phase, since Bill hovers above the ground instead of standing on it for the most of the final phase. Bill reuses his Deadly Deals and Classic Cane attacks from his first phase, but he gains two more attacks that are exclusive to his final phase. This phase is not available in Simple Mode.

* **Glitched Teleportation** - Since Bill is starting to glitch out, as he begins to deteriorate, he will randomly teleport to the opposite side of the screen. If the player gets hit by his abrupt teleport, the screen will glitch and the color aberration will briefly increase, while also randomly having the player(s) use a random weapon from the entire game until the "switch weapon" button is clicked (even if the player has not previously equipped the weapon that was forcibly given to them for the time being). Bill's location after the teleport varies from the left side from above, the right side on the ground, the right side from above, and the left side on the ground. It is recommended to stay in the middle of the screen, when this attack is done.

* **An Eye on You** - Bill briefly turns into his angry form and his increased size makes him tower over the player(s), as a form of intimidation. Suddenly, several eyes emerge from behind and above the player(s). Then blackish-red dark lasers are shot out of the eyes, thus giving limited room for them to traverse through, until they're retracted. The player can avoid this, by dashing out of the way, right before the lasers spawn from the eyes. Bill Cipher reverts to his regular size and form, when the eyes are off-screen. However, if the player dashes away from the eyes, it is possible for them to unknowingly inflict contact damage from Bill (if he's on the ground while he's using this attack), and accidentally get hit in the process.

When defeated on Regular Mode and Expert Mode, Bill Cipher glitches into various warped versions of himself, as he says "A-X-O-L-O-T-L! MY TIME HAS COME TO BURN! I INVOKE THE ANCIENT POWER THAT I MAY RETURN!" in reverse. Then Bill is hovering with a black-and-red color scheme and a shocked/scared look on his eye. As a part of the cutscene, the player (or one of them, if both players are alive after the knockout in multiplayer mode) will use the Peashooter EX move that is aimed right at Bill Cipher's eye to shatter his body, and erase him from existence. After that happens, Bill's statue is seen in the middle of the woods, signifying his death.

## Trivia

* He is the only boss has more than one death quote for one of his phases. In this case, he has two variants of his final phase death screen, with one of them being for single-player, and the other one being for multiplayer.
* The quote that he says before the fight begins ("Welcome to the mindscape, kid(s)!") has a subtle change in wording, depending on whether or not the player is in multiplayer mode. If the player is using single-player mode, then Bill would just say "Welcome to the mindscape, kid!" during his intro.
* He is the first crossover boss on the Cuphead OCs Wiki.
* He is one of the few bosses, who actually speaks during their battle, with the other two bosses being Werner Werman and Sally Stageplay.
* He is the only boss to lose three phases on Simple Mode, thus splitting the simple version of his Regular and Expert Mode battle in half.
* Due to balancing reasons and the large number of phases that Bill has, he is the only boss whose hitpoints do not double in multiplayer mode. However, the number of hitpoints that he has still changes, depending on the difficulty setting.
* Dipper and Mabel make cameo appearances during the third phase.
* He is the first crossover boss to have his level be a land-plane combination.

### Inspirations and Similarities

* He is based on the main antagonist from *Gravity Falls* with the same name and appearance.
