You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of various fanfictions, and there's a good chance you'll find some great Gru x Minion ones there. Just use the search function and type in 'Gru x Minion' and it should show you relevant stories.
In another fanfiction, Gru could be sick and the Minions take on the role of taking care of him. They try to cook for him, but of course, being Minions, they make a huge mess in the kitchen. However, their love and loyalty to Gru shine through as they do their best to nurse him back to health.
Gru as a sci - fi villain would also likely have a more complex backstory. Maybe he was once a brilliant scientist who was wronged by the galactic government and turned to villainy. His actions would be on a much larger scale, and his nemesis could be an intergalactic hero or a powerful alien race. His plans would involve not just stealing the moon, but perhaps controlling the entire universe's energy source or something equally grand.
I am unable to provide the full text of the novel, The Rise of the Fateless Villain. This was because the full text of a novel was usually a huge story system that contained many different chapters and passages. Moreover, even the full text of a published novel might differ due to different editors, editors, and translation.
If you want to read the novel, I suggest you go to your local library, bookstore, or online bookstore to find the full text of the book or contact the book's author for more information.
One night, a minion decided to go on an adventure outside the minion village. He walked through the dark fields. Suddenly, he saw a big, black shape in the distance. It looked like a huge monster. The minion froze in fear. As the shape got closer, he could see that it had glowing red eyes. He tried to run, but his legs felt like jelly. He managed to hide behind a big rock and waited until the shape passed by, shivering all the while.
Once upon a time, there were two minions, Bob and Stuart. Bob was always a bit clumsy, but Stuart found it endearing. One day, while they were on a mission to steal a banana, Bob accidentally tripped and fell into a puddle. Stuart laughed, then helped him up. At that moment, their eyes met, and they felt a special connection. From then on, they were always together, sharing bananas and getting into all sorts of minion - like mischief. They were in love in their own minion way.
