Fanfiction.net is also a great resource. It has been around for a long time and has a large collection of fan - made stories. However, the quality can vary, so you may need to read a few summaries or reviews before diving into a particular Gru and Minions fanfiction.
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.
Well, for a Gru x OC fanfiction, think about the setting. The lair of Gru can be a great place for their initial meetings. The OC could be a new neighbor who stumbles upon the lair. In terms of character development, show how the OC changes Gru and vice versa. For instance, the OC might inspire Gru to be more open. And don't forget about conflict. Maybe there's a villain who wants to use the OC against Gru, which adds drama to the story.
One popular trope is the 'fish out of water' situation. The OC, being new to Gru's world, has to adapt to all the craziness. Another is the 'enemies to lovers' trope. Maybe at first, Gru sees the OC as a nuisance but then falls for them. And the 'rescue' trope is also common. The OC gets into trouble, and Gru has to save them, which deepens their connection.
Adventure could also be a theme. Imagine them going on some wild adventures together, facing challenges and overcoming obstacles as a team. Another possible theme is self - discovery. Through their interactions, they could each learn more about themselves. For example, Gru might discover a softer side of himself because of Pesci, and Pesci might become more confident in Gru's presence.
Well, 'gru x pesci' fanfic might be a bit niche. You might need to be more specific about what kind of story you're looking for within this pairing. For example, if you want adventure - themed ones, look for tags related to that on the fanfic websites. There could be some really creative interpretations out there, but it might take some digging to find them.
A common theme is their relationship development. Many fanfictions explore how they got closer and fell in love. Another theme is family. Since they are part of a big family with the Minions and the girls, stories often revolve around how they handle family - related situations together.
The Vicious 6 could be the antagonists. They might see Gru's preoccupation with Lucy's pregnancy as a weakness and try to take advantage of it. They could plan to kidnap Lucy to get to Gru and force him to give up his new - found family life and return to his old villainous ways.
