White Lantern Kyle Rayner found the program in his ring and then activated the tutorial, once he was safe in his own home. Changing hair, eye and skin colour. The names of people and things. Then changing things back. Which made him realize the power of the Master PC. On its own. 'But now it's in one of the most powerful tools or weapons in the universe. Which include the powers of one of the most powerful computers in the universe. In what was likely the most powerful version of those power rings. Who knows what kind of power boost would come from that? Which begs the question, should I use this or not?' Kyle thought, remembering how much power he had as Ion. As well as the trouble of not abusing those powers.
What Kyle didn't know was the Master PC was like his power ring, as it had a rough intelligence. Enough to get what it wanted, most sex as well as pleasure of it's users and others. But it was not like Ion who let it's partner use it powers, it was more like Parallax which controlled it's partner. Not total control like Parallax. Which is why Kyle didn't notice a slowly building desire to use the Master PC in his mind, as well as sense of using it was okay.
'Well, what's the worse that can happen?' Kyle asked himself, as he began to use the mental link to his Power Ring type into the computer and change bars.
