A Plague of Demons By Keith Laumer Plot Synopsis

              John Bravais is an American spy that discovers something he never should have. On a mission where he is observing the battlefield of an Algerian exercise, he notices a tank going AWOL. When he investigates, he finds an alien stealing the brain of the soldier operating the tank. His horror was confirmed when he was able to kill it with a poison dart. He heads to his fellow spy named Felix, who decides the best thing to do is to turn John into a superhuman with cyborg technology so top secret the secretary of defense does not know about it! John lets loose fury on the aliens and takes out several, but they catch him in the end. He reawakens in another world in a seventy foot tall war machine with only his brain left! He is controlled by a voice called the Overmind, but somehow escapes its grasp. He is in the heart of the alien world that killed him and took his brain, and he wants revenge...

Diaperboy

              Willie Windsor may sound like a person who loves children, but be very fastidious.  This is a fifty four year old man who is too adamant to grow up. He acts like a baby, and I mean that literally. He wears diapers, eats real baby food without any punctiliousness, he emolliates his skin by shaving daily, and he even has the tenacity to have enlarged baby furniture in his house.
              Somehow he has a girlfriend intrepid enough to stay with him hoping to have an auspicious relationship. Not to mention he doesn't mitigate the situation by actually using the diapers for their intended use! Windsor is extremely assiduous in keeping this character up, so much that his ex-wife (no surprises there) believes that he is trying to relive his old acting career by putting on this act. He was actually reported to be an exemplary actor in his time.
             Now Willie is reported to say (in baby talk, of course,) he spends his days playing with his girlfriend and scaring parents and children on the playground in the state park. The question most of you are probably asking is, why? I believe that he does it so he doesn't miss being an actor so much, but i here some say that he does it to make up for a bad child hood. I guess you will just have to ask him if you see him one day. Remember this, if there is a bad smell around him, you can probably guess what he did.
