Who is Superguy? Combine the very best qualities of Superman, Spider-Man, Captain Marvel, and every other superhero you've ever heard about. Subtract all their weaknesses. That won't come close to Superguy. He's a hero's hero. He's the greatest. He's the best.
He isn't in this story.
Superguy spends all his time zipping around at ultra-high speed fixing world-threatening problems before the average person even realizes that there are problems, which is good for the world but doesn't leave Superguy much time to dictate his memoirs. At best, he can drop a yellow Post-It (tm) note from time to time. Most stories set in the Superguy universe are about the other "minor" heroes and heroines who save the day on their own because Superguy is never around.
Or is he?
I've got some vague, general plans to write some stories set in the Superguy universe when some of my other writing projects are finished. The series will be called Unnatural Tales and will focus on a group of supernatural, other worldly, or just plain weird heroes whom the local newspapers have dubbed "The Unnaturals." Some issues will feature just one or two members of the group while others might include all. I also intend the writing style to range from pure heroics to pure comedy to even creepy horror.
No ETA as of yet.
