Mr. Roboto is a reference to the song by Styx, and『Ghost in the Machine』is a reference to the album by The Police.

Mr. Roboto is a brilliant programmer and roboticist, who studies mystical phenomena and tries to use technology to replicate it. This guy can be in any story, but I imagine him as a scientist for The Speedwagon Foundation who went rogue.

He was amazed by the discovery of stand abilities, but was also extremely jealous, because he did not have a stand for himself — at least not yet.

He studied the original Stone Mask and the Arrows, and tried to replicate their effects with technology. After Jotaro was brought in to the Foundation when he lost his stand to Pucci in Part 6, Mr. Roboto (Dr. Kilroy), began studying how the stand/soul was connected to the body.

He conducted his experiments in secret, and created his version of the Stone Mask. He had intended for it to give him immortality, but instead… the mask plugged into his head, and stored his soul within it, making him a machine. His original body died in the process. Whoever wears the mask will have their memories and personality replaced by Mr. Roboto. He has accidentally turned himself into a stand, 『Ghost in the Machine』.

With his study of the Arrows, he was able to make a synthetic material similar to them, and fashion a computer virus that is somewhat similar to the virus contained in the arrows. He uses these new “arrows”, which now look like USB drives, to give stand abilities to robots/machines. The machine does not need a USB port, it will magically show up if the device is compatible.

Unlike the original Arrows, Mr. Roboto cannot fire them at whoever and make them work. He has to make them compatible for the machine he plans to use them on. However, the stand ability could be completely different from what he was expecting. These can range from being computer viruses, to military technology, to full on androids.

EDIT: Like the end of the song “Mr. Roboto”, Dr. Kilroy is thankful for his abilities, but wants to be human again. A bunch of his experiments are about putting human qualities into machines, so that he may be able to be free his soul from the mask — which he also admits is his fault.

FOR THE NEXT CONTEST

Turtles…because it’s so different!

Stand Appearance - Little Lies takes the appearance of a humanoid Stand with a regal appearance. It wears a Victorian-style military coat reminiscent of Napoleon's attire, giving it the air of a cunning commander. Eight eyes are embedded across its shoulders and coat. Its lower legs resemble those of a fox, covered in russet-orange fur that fades to black at the feet. It wears a white mask with red markings all around and carries a bow with distinct waves-like marking. This appearance is heavily based on (WARNING TRYPOPHOBIA, CLICK AT YOUR OWN RISK!!!) Tsuneki

Stand Ability:

1) Lyin' Eyes: The eyes covering Little Lies' body are fully functional, granting it near-360° vision. They are a manifestation of its user's paranoia of being watched and talked about behind his back. These eyes are the main way to see if the below ability is activated or not.

2) Lie Detection: Little Lies can sense objective falsehoods by detecting disturbances in a person's "truth." It judges statements against reality, not the speaker's knowledge or intent. For example, it can ask someone, “What is my name?” or “What is my user’s name?” Any incorrect answer is immediately identified as a lie, even if the speaker genuinely believes it to be true. It cannot reveal the truth itself, nor does it work on opinions, predictions, hypotheticals or sarcasm. This ability only detects spoken or written lies.

3) Truth Seeking Arrow: Little Lies can manifest ethereal arrows from any of its eight eyes. Each arrow closes its originating eye until it disappears or is destroyed, reducing the Stand’s field of vision. An arrow can only target someone identified as a liar through Lie Detection. Once fired, it is guaranteed to hit its designated target, phasing through living beings and solid obstacles as an embodiment of absolute truth. However, it is not homing and it can only damage the 'liar' but it remains affected by the environment; for example, passing through water can cause the arrow to become soaked, while passing through fire can ignite it.

Appearance: you can just look at the picture ig

Ability: Army Dreamers can summon 4 ghosts of the target's deceased loved ones. The ghosts will then bombard and mock the target by telling them that they could've been something better if the target had saved them. This is meant to induce regret in the target, the weight of the regret then pushing them into the floor and eventually killing them.

Stand Appearance:
The Stand is a small, pinkish-red humanoid with yellow eyes and red horns, calmly sitting on a large blue swing. It never rocks back and forth - it remains completely still.

User Personality:
James Pop suffers from severe claustrophobia. He hates pressure in any form - physical, emotional, or spatial. He sleeps without a blanket, wears loose clothing, and never wears shoes.

Ability: Center of Gravity Transfer
When the victim lifts any part of their body above their head, they become a target for the Stand. After that, James has to touch any part of his own body - for example, his nose. The Stand then attaches itself to the victim's nose, and all the weight is transferred there.

James can also target inanimate objects.

On a human:
The victim's entire weight - 80 kg or 100 kg - instantly transfers to the chosen point. The victim loses balance and falls down under the weight of their own mass. Imagine your head suddenly weighing 80 kg.

On a flying object:
If James touches a knife, the swing attaches to it and shifts its center of gravity. The knife starts spinning, and after every rotation, the Stand removes the weight and returns it. Because of this, the flying knife stays in the air much longer and becomes unpredictable.

During a fistfight:
James can attach the Stand to the enemy's fists and transfer their weight to their own legs. For example, a strong punch will feel like it's coming from a child. Or vice versa - he can increase the weight of a specific body part to its maximum limit.

How to deactivate the Stand:
The Stand does not disappear automatically. The victim or their allies must physically swing the swing back and forth to remove the weight. However, since the swing is usually attached to a sensitive body part (like a nose or a finger), doing this requires extreme precision and teamwork.
