The Virtual Genocide System (VGS) is a headset designed by Dr. Kuseno. The headset is meant to catalog the data and simulates battles between the wearer and monster data stored in VGS.

Overview

The VGS works by reading the brainwaves of the wearer, and simulates battles between the wearer and monster data stored in VGS. The wearer pictures the scenario and the scene of the fight in their head and VGS will carry it out in the simulation, with the resulting battle is visualized on an external monitor.

Another feature of the VGS is the ability to create ghosts of the user. This is done by downloading the data of the user into the VGS and having the user fight his own ghost with the intention of strengthening the user's abilities. However, the VGS is incapable of registering certain abilities into its system, and it is also heavily affected by the user's thoughts. Examples of this are seen when Metal Bat fights Carnage Kabuto in the virtual simulation, but the battle ends when the VGS deems Metal Bat's injuries too serious to continue, failing to register Metal Bat's fighting spirit. Another example is when Zombieman's body is destroyed, leaving nothing but his head, yet the VGS continues to go on because Zombieman doesn't think his injuries are very grave. When Saitama fights himself from the day before based on the data collected, Saitama defeated him in a single punch. This could signify a few things:

1. Saitama truly became significantly more powerful than he was yesterday, but this assumes that the VGS is capable of fully simulating Saitama's full power.
2. The VGS is incapable of properly registering and downloading Saitama's power and thus created a ghost with only a fraction of his true power; however, it registered the actual Saitama as far more powerful than the ghost, so it is capable of registering more power. This begs the question of why would it hold back on the ghost when it could have made it stronger.

Regardless of what actually happened, Saitama believes the data is unreliable.

Plot

Before Genos meets Gouketsu, Dr. Kuseno invents the VGS and gives it to Genos. Genos easily defeats all enemies in VGS artificially created by Dr. Kuseno. Once he defeats them, he takes his training to the next stage by uploading data collected on monsters he fought and collected data on into the VGS and engaging in simulated battles with them.

Once the simulated battles are finished, Dr. Kuseno advises him to create a ghost of himself by uploading his battle data onto the VGS. Genos does as he says, and he trains diligently with his ghost. After spending some time training with his ghost, Genos wants to see his improvement and aims to test his ghost against Saitama. So he takes the VGS to Saitama's apartment and asks Saitama to test the headset. Saitama is reluctant at first, but he eventually agrees and tests out the VGS.

After Saitama finishes the battle simulations, Genos is disappointed by the anticlimactic results, but realizes that it was naive to think he could understand Saitama's power through a simulation. Meanwhile, Saitama realizes he punched holes through his apartment wall during the simulation and becomes enraged.

Genos wants to get more data and see the VGS work in-depth, so he contacts Hero Association and sent out a call for powerful heroes to gather at the association's headquarters to get more reference data for VGS. Sneck, Metal Bat, Zombieman, and Superalloy Darkshine all agree to test the VGS. The heroes then engage in virtual combat with Carnage Kabuto.

Once all of the heroes finish battling him, Superalloy Darkshine asks Genos if there are any more powerful monsters in the VGS. Genos tells him he could upload a ghost of himself and fight the ghost, and Darkshine does just that. However, he accidentally fights Saitama's ghost and is defeated in a single punch. The VGS breaks, and the heroes believe the device is bugged.

The next day, Genos comes back to Saitama's apartment with the repaired VGS and asks him to do battle with Saitama's ghost from the day before. Saitama agrees, but as he puts on the helmet, Genos begins to panic, believing if Saitama loses to his ghost, he will be affected mentally and decide to quit being a hero. Genos tries to explain to Saitama what he is getting into, but by then, the virtual battle already started. When it is over, Genos consoles him and tells Saitama it is okay to have lost to his ghost, but to the cyborg's shock, Saitama defeated the ghost in one punch. Genos marvels at this, wondering if Saitama became much more powerful than he was yesterday. Saitama tells him it was just unreliable data and goes on a short monologue describing how training in a virtual simulation will not give you any growth, with Genos vigorously taking notes.

List of VGS battles

Participants	Results	Notes
Genos vs. Mosquito Girl	Genos defeats Mosquito Girl in one shot.	Genos states he will not be careless this time.
Genos vs. Deep Sea King	Genos uses Machine Gun Blow and Incineration Cannon, defeating Deep Sea King.	Rain sounds in the background, meaning Genos is fighting hydrated Deep Sea King. Subsequent simulations show Genos with greater than 70% chance of victory against any Demon-level monster.
Genos vs. Carnage Kabuto	Carnage Kabuto defeats Genos in two hits. 54 further simulations: 54 Carnage Kabuto victories.	No mention of Carnage Kabuto going into Carnage Mode. Genos realizes he is nowhere near Carnage Kabuto's level, despite all his upgrades and time spent with Saitama.
Saitama vs. Monsters	Saitama defeats all of the monsters in one hit.	Names of the monsters not specified, and Genos only mentions that Saitama wrecks all of them just like in real life. We hear the OPM theme and sound effect indicating a single punch.
Saitama vs. Ghost Genos	Saitama defeats Ghost Genos in one hit.	Saitama states it is like a video game but way easier.
Sneck vs. Carnage Kabuto	Sneck is defeated in 2.52 seconds.	Genos says Sneck is too weak for a reference and moves onto Metal Bat.
Metal Bat vs. Carnage Kabuto	Metal Bat lasts three minutes but is then defeated.	Carnage Kabuto transforms into Carnage Mode somewhere during the fight. VGS terminates the simulation after it deemed Metal Bat’s injuries too severe to continue, but Metal Bat argues that those injuries would not stop him in real life and that his Fighting Spirit will revive him, implying VGS isn't properly simulating his Fighting Spirit.
Zombieman vs. Carnage Kabuto	Carnage Kabuto quickly destroys Zombieman, leaving only his head. A one-sided beat down continues for one week, but Kabuto eventually exhausts himself in Carnage Mode and becomes immobile. Zombieman kills him with a counter-attack.	Simulation clock is sped up. Zombieman says the VGS did not stop the simulation because his brain did not register those injuries as serious damage or real danger. Genos believes Zombieman's body is too odd and is an unreliable reference.
Superalloy Darkshine vs. Carnage Kabuto	Darkshine unleashes his full strength, penetrates Carnage Kabuto's defense with his attack power and defeats him after 15 minutes of head-on assault.	Carnage Kabuto is in Carnage Mode. Darkshine states he is much stronger than anticipated. Genos asks if his body has been modified, to which Darkshine replies it is only his pure muscle. Genos ponders to himself if it is time to ask Dr. Kuseno for muscle upgrades.
Superalloy Darkshine vs. Ghost Saitama	Ghost Saitama defeats Superalloy Darkshine in one hit.	The other heroes did not actually see Saitama, only a silhouetted baldy. VGS breaks afterwards, and the heroes think the device is bugged.
Saitama vs. Ghost Saitama from yesterday	Saitama defeats his ghost in one hit.	Genos tries to comfort Saitama by telling him his opponent was himself from yesterday, but to his shock, he sees Saitama defeated his ghost in a single punch. Saitama scoffs at the idea of ever losing to himself, causing Genos to frantically take notes.

Trivia

• It is said that ONE had spent over 10 hours to make changes/amendment for the script of Genos, Training.
