A rambunctious bunch of simple-minded homunculi, Minions are a similar size and shape, but have unique features to tell them apart, such as height, number of eyes, roundness or secondary features such as hair, eye/pupil size or clothing.
Minions wear metal goggles accommodating their number of eyes, blue overalls with Gru's emblem on the front, and black gloves.
Minions possess few additional physiological characteristics; with a crack and a shake, they can double as glow sticks for activities in the dark, such as going through ventilation ducts. They additionally can survive without air.
Though there are large number of minions, there are only about forty-eight possible combinations of height and build (short and chubby, medium, tall and thin), hair (tall buzz-cut, short buzz-cut, sprout, combed, spread out, bald), and eyes (one, two). One-eyed minions are always almost all small, although a tall one-eyed minion appears in a promotional artwork.Tall Minions are all with Sprout-Cut Hair.
After the defeat of the Organization XIII's and during the repairs of Radiant Garden, many of these strange beings were without a home and searched for jobs, they were all were hired by Cid Highwind and his gang as his own staff with little care for money but to do something. Althought many have been annoying at first after the first few weeks, until Cid gotten to know them more after seeing their hardwork on a few machines and fix up the place he had been working on for repair.
Sometime afterwards the Keyblade wielders arrived at the time when the Galactic Empire sent their 'assistance' for the planet's inhabitance after the latest Heartless attack, he introduced the wielders to the extra staff as they were working with dangerous weapons, chemicals and construction. As they were being introduced by the strange beings, he was too late to warn Kairi before she took out a banana as they love fruit most of all, causing a lot of mayhem in the building until things have calm down.
The Minions were called in an emergency meeting by Cid and with Merlin to gather supplies to the Highwind after many upgrades to take off as things are getting serious with the Empire and the Heartless' new masters taking control of the planet.
- "Ladies, Gentlement, and non-human beings. I like to introduce you all to my new staff. They may look dimwitted and immature, and destuctive in numbers. But they've became close as family. most of all, they're very cheap for hire which makes it good enough for me."
