Virtual Genocide Simulation

The VGS (Virtual Genocide System) is a headset designed by Dr. Kuseno. The headset is meant to catalog the data from monsters that reads brainwaves 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 effected 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 VHS 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 three things:
 * 1) The VHS is incapable of properly registering and downloading Saitama's true power and thus can't create a proper ghost
 * 2) Since Saitama had the mindset of being victorious over his past-self, this caused the simulation to be rigged toward Saitama.
 * 3) The data collected by the VHS didn't represent Saitama's true power, and the ghost inserted in the VHS was just a fragment of what Saitama is truly capable of.
 * 4) Saitama truly became more powerful than he was yesterday, although this is the least likely because Saitama believes the data to be unreliable and already had the mindset of victory over his ghost.
