VHS Vanya (human)

Vanya is unique in that, as a human, he has a colossal amount of health (HP) or determination, which, combined with his insane code-breaking powers, makes him a virtually unbeatable boss.

As in the original VHS!Sans trilogy, the fight with Vanya is divided into three stages:
• Phase 1: "Now You'll Never Leave" - ​​Vanya is calm, confident, and uses basic attacks. He looks human, but has a creepy grin and glitchy eyes. He warns that no one will leave this place alive.
• Phase 2: "Better Start Running" - His human body begins to deteriorate greatly from the magic overload. His skin turns pale, and streaks of glitches run across it. His attacks become frantic, chaotic, and incredibly fast.
• Phase 3: Inner Torment - The final stage, where Vanya's human shell is nearly destroyed by the hacker's code. He turns into a creepy digital silhouette, and the entire arena around him becomes a continuous, unstable glitch space.

Since Vanya has inherited VHS!Sans' powers, his magic relies entirely on reality hacking, glitches, and "system errors":

1. Glitch-Gaster Blasters: Instead of the usual skulls, Vanya summons enormous blasters distorted by interference. Their beams don't just burn, they "erase" space and cripple the enemy's code itself, causing lag in their movements.
2. Distorted Bones: He attacks with sharp bones that constantly change texture—from black and white to composed entirely of television static. Hitting an enemy with one of these bones disorients them.
3. Breaking Teleport: Unlike Sans's classic stealthy teleport, Vanya's teleportation appears as a sudden glitch (the frame cuts off and then re-cuts). At this moment, the characteristic screeching sound of a broken tape can be heard.
4. Gravity Manipulation ("Soul"): Vanya can hurl enemies against walls by changing their gravity. However, in his case, this is accompanied by a visual effect of an "inverted screen" or a drop in the victim's FPS.

Unlike Sans's skeleton, Vanya initially appears like a normal guy. But due to "code corruption," his human body begins to behave abnormally:
• VHS Effect: From time to time, its outlines "twitch" like when the signal is bad on an old TV. Pixels and digital noise may fly around it.
• Anatomical Glitches: When Vanya uses his powers at their maximum, his face and body may become unnaturally deformed and stretched (as happens with VHS!Sans during combat). His eyes may turn into static white noise or screens with the word ERROR.

VHS Vanya is an original character (OC) for your own universe or fanfiction, created at the intersection of human nature and creepy digital mysticism from an alternate Undertale universe called Undertale: The Hackers End.
Since he's a human with VHS!Sans' powers, his appearance, abilities, and combat phases can be incredibly dark and epic. Here's a detailed concept of how his abilities work in a human body:
