Error404 sans

Before the destruction: Before the Void claimed him, 404 was William Ding Gaster of AlphaTale. He lived with family and friends in a world drowned in grief and constant war, which forged him into the coldest, most serious version of Sans. Even through the suffering, he built deep trust and love with those around him. But everything broke when his mother, the Astral Mother Wendy Ding Gaster, forced him to choose: sacrifice his brother Jacob, or lose the freedom they fought for. William chose the rebellion. That decision won them the war, but it sparked an eternal rivalry with Jacob. When Jacob returned years later to destroy AlphaTale, William and Adam confronted him. Adam died in the fight, and William unleashed a strange, ancient power from within - ending Jacob, but dragging them both into the anti-void. Victory, but at the cost of his world, his brother, and his soul. After the destruction: He had won the battle, but at what cost? He had become a very corrupted monster and had gone insane, thinking of the most darkest deeds. Error!404 hid away in a special part of the Anti-Void that only he can access, called the Mainframe. It is a place where he can see all activity in and out of the Anti-Void. He has been there ever since, never to be in contact with other AUs, slowly driving himself more and more insane with grief in his isolation, only accompanied by "one other". Until, he eventually found a way out, and from there on, worked to rebuild his world and fix his mistake, and had met many people along the way. Some enemies, others allies. Some friends, other puppets, and even frenemies. Puppet Series/Error and 404 adventures AlphaTale: A New Puppet Book 1 AlphaTale: A New Puppet Book 2 AlphaTale: A New Puppet Book 3 404 Catastrophe.

Role title: Error!404 is a core entity in AlphaTale and is the self-proclaimed 'God of The Multiverse' mainframe destroyer. Abilities: Mainframe Strings / Black Strings - Added in Puppet Book 3. Not his first choice, but a tool he uses. They don’t just bind and control targets; they twist instincts so victims betray themselves. Even soulless entities get puppeteered as the strings rebuild mind, spirit, and primal functions, forcing them to work against their own will. Reincarnation - Triggers when 404 dies or takes lethal damage. The Mainframe uses a stored copy of his code to rebuild and revive him. Revival time scales with damage. The more destroyed he is, the longer it takes. Immortality - 404 is functionally deathless. Alphatale code + Mainframe code work together to prevent death by any means, even forced death. His mind is equally fortified, reinforced to resist and often ignore lethal mental attacks entirely. power/combat: 404 isn’t a brawler. He fights from range, overwhelming foes with tricks and out thinking them. Fighters in Reality 6 and beyond, like Malware, know he’s dangerous. He uses clones and dirty tactics with no honor. Post–Blue Dragon Arc he’s more hands-on, but still prefers distance. Blue Mastery: Peak Blue SOUL Alteration. 404 moves any visible object, living or dead, from any distance. On living targets he can crush their SOUL instantly, rip out Determination, or manipulate minds. He can sever coded beings from their code for erasure, link multiple minds, and create black/white holes, singularities, even reverse the Big Bang into a Big Crunch. Master Eye: 404’s unique version of the Gaster Eye all Sanses have. It lets him read Code like an open sky. He can see someone’s last bathroom use, age, LV, and Code amount. It grants access to restricted zones across the Multiverse and reality itself, even barriers others make. If a place is locked by “only with permission,” 404 can still enter. Mind Manipulation: He seizes control of others’ SOULs. He can alter, distort, and warp their thoughts, usually forcing them to serve him. Great knowledge: Centuries in the Multiverse gave him deep insight. He knows when the second AU, Underswap, was created and has predicted events years before they happen. Dark Blasters: Weapons built by the Astral Mother. They delete almost anything hit — person, object, essence, regular or glitched code. As a child they leveled mountains easily. With Mainframe upgrades, they now erase Universes and Multiverses with ease and can delete ordinary code too. relationship: Error!Sans: Mentor-student bond. They clash constantly but watch each other’s backs when it matters. Dark Nova: 404’s Giga Blaster that triples the power of his regular dark blasters. God Ray: fires in 2 shots: 1st shot freezes the target in place until the 2nd lands or they’re hit. 2nd shot kills on contact. Anyone with normal, glitched, or unordinary code gets deleted instantly. For beings with Cosmic Code, Mainframe, Nullvoid, Nexus Code, or no code, it works as a lethal death beam instead of deletion. MFTL+ Speed: - Immeasurable Speed: 404 has speeds so fast he can reach the center of universe in a matter of second to him showing feats of Immeasurable speed as shown from him standing in the absolute void a place vacant of everything.Fiberglass SOUL: 404's SOUL is deflective against any form of attack energy our magic manipulation our reality bending, making his critical hits only ones that are physical. Pixelation Manipulation: 404 can manipulate the very air, turning the particles into small pixels, allowing him to form things out of any physical material. He can also use this on himself as a substitute to teleportation. Mainframe SOUL: Ever since 404’s first contact with the Mainframe, it has given him increased strength and durability. Although once a weak passive ability, it has grown with 404 and due to the Mainframes influence on 404’s soul, it had made him immune to all magical and physical attacks from those who are weaker or near his level. Mainframe calling: Mainframe calling, allows 404 to summon the mainframe to wherever he is . this ability is useful to get more Unbound Power. This ability only lasts for as long as 404 needs it and giving boosts through out the fight soon he will overpower the enemy when don't need anymore the Mainframe take half the power also codes. Then 404 be in pain for few mins but stronger then before because 50% Strength left behind. King Multiverse: A cover “created” by 404, used as a pawn. Mutual resentment, passive-aggressive dynamic. Alpha!Chara: First love. Met in Hotlands over ice cream, 4 years chara is a male wife together, nearly official before the siren. 404 never moved on; refuses other romance.Usually 404 affairs. Alpha!sans: his ghost phantom beloved brother who got killed by infected back in alphatale. Player/UnderPlayer: Broke his no-dating rule. Years together, nearly married before he remembered his purpose. Another affairs. Null: Smartest, most dangerous foe. Only one who truly makes 404 cautious. Total ideological clash.

Source of deepest pain and his need to prove himself — a chokehold he can’t escape. Infected: Bleeding, wordless hatred. Loading: Wants his Multiverse energy. Constant conflict. Abyss!Sans: Annoying AU protector who blocks him from the Abyss. Many fights; Abyss always escapes. CORE!Frisk: Intriguing.

Later on, however, he is proven wrong. -Error!404 hates pranks because they're childish and a waste of time to him. -Error!404's Realm is a giant cliff side that leads into the very core of the Multiverse and has an endless ceiling covered with scenes of AUs, visions of those he has control over, and drawings that Ink has made. -Error!404 has watched anime with Error a few times and also forced him to watch "dirty anime" to improve Error's mental resistance against disgusting things.

Error404's domains realm sanctuary:

Nexus Void: The Nexus Void isn't empty — it's too full. A drifting, starless limbo where broken doorways, dead gods, and lost data hang suspended like dust in still water. Gravity forgets itself here, time stutters, and everything that ever fell through a crack in another realm ends up washing ashore. Travelers use it as a crossroads, because if you know the right currents, you can step from anywhere to anywhere, but stay too long and the Void starts remembering you as one of its lost things. Null Sector: If the Nexus Void is the ocean, the Null Sector is the trench. A cold, black, anti-signal zone where light, magic, and code all go to die. No stars, no noise, no background hum. Just perfect geometric ruins — vast black cubes and silent server-spires — half-buried in static ash. Things that live here have learned to live without being perceived at all. It's where exiles hide, secrets are buried, and anything that needs to truly disappear is thrown. Mainframe: The Mainframe is the opposite — a vertical, living city-realm of light and order. An infinite lattice of crystal towers, data-rivers, and humming transit veins, all orbiting a single white core that ticks like a heart. Everything is connected, everything is logged, everything runs. It's where the architects, archivists, and high protocols live, building realities the way you'd compile software. Beautiful, brutalist, immaculate — and utterly intolerant of the glitches that leak in from the Void and the Null.
