Character Evolution
His own craving for human blood led him to study vampires and because of this study it put him in a few battles with Dracula.
He would give up on vampires and switched his study to the man called Nova. He realized that the Xandarian computers are more suited for power. He would go to Xandar and download himself to the main computer system, then switched to H.E.R.B.I.E. the robot. Eventually arriving back on earth he would then download himself to the Baxter Buildings main computer and attack the Fantastic Four. This would lead to his death, or does it?
