Description:

What if the 3D Hypno Ring didn't work?
In this series, the canon diverges from the plot of the first book into an alternate timeline where Dr. Diaper's plan to take over the world nearly succeeded. That is, until Captain Underpants was created at the last minute by George and Harold via Melvin's prototype inventions (In particular the combine-o-tron and the PATSY 2000)... and combined him with Mr. Krupp to actually bring him "to life."

Now he's this strange and unstable fusion of a man, hologram, and machine. Not only that, but robots are freely running amok, there's conspiracy theories that the moon is fake, and Earth is a bit of a mess...

Notes:

At this time each story is intended to be standalone and can be read out of order, but all point towards a common plot. Because this series is based upon the first Captain Underpants book, the story makes the most sense if you have read it.
