The supervirus is a mystical command from unknown origin with unlimited power. It existed for generations. A million of years ago it pierced its way trough the universe, destroying everything in its path. It has now stopped doing such awfull things. The terrific demons inside are sleeping these days, and the universe can only be peacefull for as long as they do.
But if one person carries the supervirus, he obtains the demons ultimate power, and he can control it to do everything he wants. The effect only lasts for a short time. The person can lenghten that time by doing what the demon itself would do. If that person refuses, his body and soul will be sacrified, and the demon will awaken from its endless slumber, and he will destroy the world and the rest of the universe.
Whatever you do, do not use this command in SRB2JTE:
"I CARRY THE SUPERVIRUS"
