Dumb Owl saw Supreme Superboy's current condition and felt his heart pounding.
Supreme Superboy kept tearing at the bones and flesh on his own body, using the most brutal and savage method to resist the overwrite of the World Forger from the upper reaches of the Over-Time Stream. This method was simply too...
Idealistic.
Yes, idealistic. Superman was synonymous with idealism, and Supreme Superboy was no different.
By common sense, if any normal superhero used this method to harm his own body, he would only suffer severe injuries and die. Had anyone ever seen someone pull out his own bones and then shove them back in? When had Superman ever possessed high-speed regeneration?
Yet Supreme Superboy was now displaying something resembling self-healing. Idealism had briefly granted him this ability, helping him maintain his self-perception and resist the World Forger's overwrite in reverse.
He kept maintaining his original appearance, locked in a tug-of-war with the World Forger from the upper reaches of the Over-Time Stream.
Dumb Owl had to consider that perhaps...
This was the best time to use the essence of New 52 Superman.
In his original plan, he had laid a trap for Supreme Superboy.
Although Supreme Superboy had now seized control of the Cosmic Tuning Fork, and although Dumb Owl's original control had come from the Anti-Monitor and the Monitor, that did not mean Dumb Owl had accomplished nothing.
He had left a back door in the Cosmic Tuning Fork, using Doctor Manhattan's quantum power—of course, Doctor Manhattan would never allow his experiment to fail just because the Anti-Monitor and the Monitor had changed their minds.
He could use this back door to retaliate against Supreme Superboy when he rebooted the universe, then take the enormous risk of trying to fuse the essence into his body.
