create a mob that looks like a Skeleton which has the following appearance: 'Error404!Sans is a towering skeletal entity, far larger than a normal skeleton or Wither. His bones are void-black, constantly glitching with bursts of red and cyan data static. His left eye socket glows with a corrupted red 404 symbol, while his right eye remains an empty void leaking code-like particles. His body is wrapped in tangled, glowing strings—representing broken timelines—floating and twisting behind him like corrupted tentacles. His tattered cloak glitches violently, distorting light around it as if space itself is unraveling in his presence. When idle, his form flickers, leaving ghostly afterimages a few blocks behind.
' and the following behavior/capabilities: 'Error404!Sans, the Judge of the Alphaverse, acts as a living enforcement protocol against multiversal instability. Upon entering the world, he generates a powerful “Null Zone” that suppresses reality itself—causing mobs to vanish, particles to jitter, and music to cut out entirely. He doesn’t walk but blinks through corrupted space, his code-glitching body fracturing with every teleport. He attacks by manifesting enormous red and cyan Gaster Blasters forged from destroyed timelines, firing void-energy beams that ignore terrain and armor. Error404 passively drains the health of nearby players and erases their buffs, applying a unique debuff called “404 Corruption,” which causes hunger, blindness, and false damage indicators. During combat, he summons broken data phantoms from erased AUs—ghostly clones of Sans variants that explode on contact. If players survive long enough, he transitions into Absolute Null Mode, where he tears open glitch rifts to spawn infinite red strings that immobilize enemies and delete summoned allies. In this state, he becomes the embodiment of anti-creation—ignoring knockback, deflecting projectiles, and freezing time itself in short bursts. As a manifestation of Alphatale’s will, he will not stop attacking until he eliminates all “inconsistencies” in the timeline—including the player.'
