Fairy Muscles

The novelist sat at his desk. "Hmm. What should I work on today?" He moved the cursor to a file called "Alternate Fairies." It was going to be the next book in his currently on-going series, Ripples Through the Multiverse. Unfortunately, he was having trouble thinking of a world where there were no humans because the US and the USSR bombed the hell out of each other (and everyone else, unfortunately). What he thought could be the result of that was that the survivors somehow changed into fairies and merpeople. He had an idea for the world itself. But finding an idea for how those two sects interacted was leaving him ragged.
It was at the very moment when he was going to open up his worldbuilding sheet that a loud explosion and a bright flash popped in the corner of his office. He turned around slowly, unsure of what he was going to see.
Standing in front of him, or rather, floating in front of him, was a very heavily-built, humanoid with large dragonfly wings in front of him. This humanoid could be described as a fairy, but he looked like a fairy that was able to scare other fairies immediately into submission. Somehow, the novelist expected the fairy to shout into his ear "SCRAMBLE THE FAIRIES!!!" in a way that mimicked Arnold Schwarzenegger. The novelist fell to the ground.
"GET YA ASS UP, MISTER!! I CAN'T BELIEVE THAT US FAE ARE DESCENDED FROM SUCH WEAK CREATURES!!!" the fairy shouted.
The novelist scrambled up. "Y-y-yes sir. Is it alright if I-"
The imposing fairy crossed his ginormous arms. His guns weren't guns; they were cannons. "WHATEVER YOU'RE GOING TO ASK, THE ANSWER IS NO! NOW KNOCK DOWN THAT WALL WITH YOUR BARE HANDS!" He pointed at the wall next to his desk.
The novelist stared at the wall, and gulped. So much for his house. He walked over to it, placed his hands a yard away from each other, and pushed.
The only result was a very winded "All I wanted was to ask you a few questions on how you survived the post-Cold War..."
There was very quiet sound of inhaling coming from the direction of the fairy. "Well, in that case, I be happy to."
Surprised, the novelist turned around. That was quite a turn of events. He motioned to a chair near the opposite wall. "If you want, you can sit."
The fairy shook his head. "I'm good. Have to keep my wings strong."
The novelist went ahead and sat down. "What is your world like?"
Taking a large breath, the fairy started talking. "It all changed when Senator Joseph McCarthy was elected as president..."
