You have no idea in the power that I myself possess.-Royal

Royal is a large fusion of Error404 and Error Sans, (while both of whom were fused as Error666, and King Multiverse (while in his Emperor Multiverse form), and is an utterly massive and powerful fusion to ever exist, similar to the Systematic fusion of Error404, Fatal_Error, and Error. Due to being formed from 2 strong Sanses and Error Sans, Royal is one of the strongest fusions to ever exist, as well as one of the most dangerous fusions.

Appearance:

Royal is a rather massive fusion, he possesses a black crown on top of his head with a red gem on the left part of the crown, a blue gem on the right part of the crown, and a purple gem in the middle, with the crown also appearing to be a bit larger then before, almost large enough to wrap around the skull itself, and floating above him like a halo. The face is shown to be grey, but it is in different hues or shades, with the right side being a light grey and the left side being a rather dark grey. He also has 2 sets of purple eyes sockets on his head, both of his eyes generating and making a dark blue eye light in each, the iris being the same shape of Emperor Multiverse's, with dark blue lines going down both of his eyes, as he also possesses 3 mouths that are a yellow color of sort on the right hand, but become black in the other half. The neck of the fusion is replaced with black chains that keep the head attached on the torso itself. He also possesses white hands that become black, grey, and red as it goes up to the tip, with the detached hands being kept onto the body by black chains that come out of the shoulders. Royal wears a black scarf that has the number 666 on it colored purple, as well a dark blue jacket that reaches down to the ankles. He wears a red sweater and dark grey vest over the coat and wears black pants that goes down to his ankles, as well as wearing dark red high heeled boots of the Emperor Multiverse form.

Personality:

Royal, somewhat similar to Systematic, is not really a person of a single individual personality. Rather, he possesses the personality of Emperor Multiverse and Error666 inside of his mind in a similar manner to a split personality of sorts. Meaning that Emperor Multiverse and Error666, which mainly has 404 in control of said form, will often switch control with one another, although Error will often wake up inside of 666's consciousness and take over, although that rarely happens. So, in a way, Royal has the cold, remorseless, and deceptive nature of Emperor Multiverse, the Manipulative, control-freak nature of 404, and Error's short tempter and the fear of being touched.

Powers and Abilities:

Mainframe Cannon: Originally needing to use the Ruler's Might power, Royal is now able to use the MainFrame Cannon, which allows him to destroy anything that's hit by it.

Master Chains: This power is a combination of the Master Cables and the Chains of Judgement. The chains will start off red and blue, chasing down the target and once latched onto something or someone, Blue Mastery is then initiated with the color Blue and Red mixing into Black, forcing the Object or person into a forced state of binding. Then, the chains will begin to absorb a person's HP and Mana, filling Royal up in a way. The final kill is when the black cables crush the opponent into dust using Blue Mastery as a type of heavy gravity crushing the opponent with sheer strength.

Servant Chains: Simply the upgraded version of the Green Chains, Royal can wrap these around an opponent in order to absorb and Inject Mainframe coding into something or someone, causing them to get more powerful then they were before.

Overthrow Button: This button allows for Royal completely take over the MainFrame in any Eden Orb, so long as he presses the button. This act allow him to be able to control any being connected to the MainFrame, such as a Loading or an Error404.

Disruption Button: This allows Royal to disrupt an entity connection to the MainFrame, causing their powers to combust a 404's body a bit and forcefully disconnecting them, forcing them to go to the MainFrame in order to reconnect with it again. This also extends to Loading as well, which can destroy their form.

Magic Reset: A special form of the Reset button as well as an upgraded version of the Asset Reset, if Royal presses that button, the magic of his opponent is quickly reverted to that of their undertale counterpart. The buttons effects last for four days with them slowly regaining their magic.

Pixel Manipulation: Royal is able to turn the air into pixels, allowing him to be able to make whatever he desires.

Scythe of Execution: This scythe was made by Error404 for King Multiverse to use himself. Now in Emperor Multiverse and fused with Error666 in order to make Royal, the Scythe is capable of cutting and slicing through anything, with only some exceptions.

Coded Wormhole: If Royal doesn't want to teleport, he can decide to use a wormhole of any size, allowing him to traverse across any point in time and space within a timeline. This is only if he decides to bring in more people than before.

Extendable Neck and Limbs. Due to the fact that he has chains replacing his arms and neck, Royal is able to extend and retract them in anyway he desires.

Bones of Imprisonment: Royal is able to make blue bones constantly appear from the ground in order to trap and freeze the opponent in place that so that he can take the chance to kill them effortlessly.

Mainframe Ray: Royal's version of the God ray. Royal can fire a purple blast from his fingers that will kill anything and anyone, regardless of what sort of code that they have.

Mainframe Ray First Shot: The first shot of the ray would completely shut down a person's abilities and magic leaving them as a powerless being for a temporary amount of time.

Mainframe Ray Second Shot: Upon the second shot, it causes a digital footprint over the victim which causes a mass of loadings to appear and destroy the person.

Kingship Whip: Royal can swipe his hand to make a whip of light appear from his hands, with the whip being longer than the Empress State building.

Flight: Royal is able to fly into the air without any sort of aid.

Fiberglass Soul: Royal's soul is resistant to most forms of attack, both Magical and Physical, making critical hits the ones that can cause him damage.

Weapon Modification: Royal is able to self-modify his own weapons and attacks in anyway he desires, such as make them inflict non-physical damage to the opponent.

NullVoid Infliction: This ability is an automatic, only caused from Royal entering a void. Upon him entering a void that isn't an anti-void and/or the Mainframe, the amounts of stray data in the area will begin to rapidly vibrate, rumbling and possibly even collapsing the void.

Mama's Boy: Something that 404 picked up from the Astral Mother subconsciously, which Royal now possesses, he gained this 'ability' through Astral Mother due to her influences to 404 when he was William. He is capable of instilling fear into any being that holds a soul, even if he doesn't want to.

Monarchical Multiverse: Royal's version of the True Multiverse, in which he can make a small orb appear in his hand, which then expands in size and consumes the opponent, trapping them inside of the Monarchical Multiverse. This Monarchial Multiverse  is a large-scale multiverse composed of a sea of code and a large number of multiverses, and each of the large number of orbs that cling onto the opponent in order to prevent their movement. The orbs would then explode the opponent once Royal fired his MainFrame Ray. Inside, Billions or Error404s, King Multiverses, and Errors appear inside of it. Inside of this Multiverse, Royal can do whatever he wants inside of it.

Coded Operation: it is a sort of code technique that Royal can use, sometimes to use it to speed up my natural healing, or he can infuse a character with codes of multiple AUs or Multiverses in order to explode then.

Coded Hades: This technique takes out and regenerates all the negative things such as the opponent's trauma, worst anxiety, shortcomings, mistakes, regrets, and makes the pain 400 times. The opponent is unable to move and unable to go anywhere, as they are literally hung in the air by their worst nightmares.

Transformation:

A.U.T.O.C.R.A.C.Y: Royal's own B.U.T.T.E.R.F.L.Y form, in which he can activate on his own. This forms allows Royal to become exceptionally powerful, allowing him complete control over the MainFrame in order to do what he pleases to do, as well as being able to grow stronger as time goes on.

NullNova: Royal can fire beams from his wings, which can burn through 2 realities at the same time and can destroy anyone weaker then him in a single blast, even groups of people at once.

Incomprehensible Speed: Royal is able to move so fast he seems to be in 4 places at once.

Multiverse MiniGun: Royal's most powerful attack, in which zillions of either MainFrame Cannons or Beams coming from A.U.T.O.C.R.A.C.Y's wings fire at the opponent. This attack is strong enough to destroy a reality.

Tyranny: This is a Malware-Possessed form of Royal. This is a form that Malware can take over whenever Royal feels negative emotions in an extreme level. When this happens, Royal's powers increase immensely.

Mainframe Eyes: Basically the God Eyes, Tyranny can fire them out of his eye sockets and can lock onto them, twisting and turning until they reach the opponent, in order to destroy them in their entirety.

Omniversal Wrecking Ball: Tyranny can make a ball that is made of chains that is attached to his hand, being bigger then it's Outversal version, and can use it to swing and hit the opponent with it.

Decaying Aura: Tyranny has a passive ability where he has an aura of decay around him at a distance of 4 meters, with anyone caught in it decaying, their death adding to Malware's power in his true form.

Eyes of Bael: Staring into Tyranny's eyes will force a person to see their worst nightmares and fears, amplified by 100 times. It is enough to drive a person insane and even make them hurt themselves.

D.I.C.T.A.T.O.R: This form is the result of Malware possessing Royal in his A.U.T.O.C.R.A.C.Y form. This form is much stronger than Just666 B.U.T.T.E.R.F.L.Y itself, due to utilizing the MainFrame's limitless power and Malware's nigh-limitless might, becoming a form of pure unstoppable discord and anarchy, allowing to do feats that Royal had never thought possible for him to do.

TransVoid Black Hole: D.I.C.T.A.T.O.R is capable of contorting his body into a large mass of shapes as he continues to grow endlessly, which also possesses a gravity effect that can pull people into him. Should they fail to escape and get caught into his mass, they will sink in it and they'll be transported to the Transvoid where the monstrous beings and entities would most likely give the victim a fate worse than death itself.

Multiverse Crockett: An upgraded version of the Multiverse MiniGun and the second stronger attack that he can use, D.I.C.T.A.T.O.R is able to summon zillions of either MainFrame Cannons or Beams, and they are fired coming from the wings. The attack is strong enough to destroy 2 realities at the same time.

Mainframe Breath: D.I.C.T.A.T.O.R can open all 3 of his mouths, in which he can fire an energy breath attack of sorts that can delete a person from existence, as long as the person he is fighting is weaker then him. To those that are stronger than him, all that this will do is cause unbearable torment and agony never felt.

Reality Control: D.I.C.T.A.T.O.R possesses confirm over all of reality, allowing him to make or destroy anything that he desires, including being able to freeze time, distort space, cause reality distortion, etc.

Scythe of Damnation: This Scythe is an upgraded form of the Scythe of Execution, in which when he slices someone, he can slowly decay and rot a person, which eventually causes them to die from the slash wound they're given.

NexusNova: D.I.C.T.A.T.O.R's most powerful attack. After letting his power grow enough to the point where he gains 24 wings on his back, he is able to make a spherical attack with his wings, the attack being so strong that it is capable of destroying 4 realities at the same time. However, this ability takes time to build up due to needing wings to grow into power with the MainFrame continuously increasing his power very immensely.

Notes:

This form is a combination of the Error666 form and the Regal form from Staffverse, which makes it have Error666's immortal regenerative nature of being able to deny death itself and Regal's powers which are amplified by the additional fusion of Error itself.

Royal and Systematic, if they were to meet, would sort of be friends in a way, due to the both of them being triple fusions.

In order to fuse with Emperor Multiverse, who is stronger then Error404's base form, Error404 had to fuse with Error to make Error666, which is stronger then Emperor Multiverse, in order to fuse with him. And due to Emperor Multiverse having a piece of Error404 inside of him, it made the fusion possible.

This form is much more stronger then Regal in the Staffverse, for very obvious reasons. And if they were to meet, Regal and Royal actually wouldn't like each other that much.

Royal's version of the MainFrame Ray is much stronger, due to both Error and King Multiverse having learned it in a much more earlier time, which increased the power of the ray itself.

The MainFrame ray is so powerful, he once used it to destroy 15 AUs at the same time by making a large digital footprint that covered them all, causing an exceptionally large mass of Loadings to appear and destroy the AUs themselves.
