The concept of Minions being based on a true story grew from the understanding of sidekick characters in storytelling. Historically, sidekicks have been an important part of many tales. They can be clumsy, loyal, and often provide comic relief. The creators of Minions recognized this and decided to create a whole species of such characters. They built on the idea of how these characters interact with their leaders, how they get into trouble, and how they can be endearing despite their flaws. This led to the development of the Minions' concept from a simple true - story - inspired idea to a full - blown animated phenomenon.
The concept developed from the idea of common character types. There are often characters in stories that are the helpers or the ones who do the grunt work. Minions are an extreme and comical version of such characters. They took this basic concept and added their own unique spin with the yellow color, the gibberish language, and the overall goofy behavior.
Well, it developed as a way to play on the idea of loyal but not - so - smart assistants. In real - life stories, there are always those characters who follow orders blindly without really understanding the full picture. The creators of Minions took this idea and made it into something really fun. They thought about how these characters could be in a world of their own, with their own culture and ways of doing things, which led to the creation of the Minions as we know them today.
