Gru's Minions are small, yellow, pill-shaped humanized creatures that have one or two eyes, and one of the most notable characters in the film.
A rambunctious bunch of simple-minded beings, the 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. They choose to express themselves through actions, not words: their "language" is fairly basic, they speak in a strange jabber; except for the odd human word every now and again and occasional Spanish-sounding words like "Para tú" (roughly "for you"), their language is incomprehensible to most humans, though they do understand English. It is also possible to isolate elements of Japanese from their speech patterns.
Their existence as artificial beings is noted by the final schematics in the little girls' room. It is however unknown how they came to be or who made them. One of the shorts in the DVD suggests they are made from a single strand of mutated DNA. The minions wear metal goggles accommodating their number of eyes, blue overalls with Gru's symbol on the front, and black gloves. They enjoy playing with Agnes, Edith, and Margo, as seen in the toilet paper fight scene.
They are impulsive creatures with little self-control, but with a wide-eyed wonder and odd innocence that endears them to viewers and makes them relatable. They can be pesky when they are doing weird interactions with other people, animals, or objects. The Minions have standard English names such as Dave, Bart, Ted, and Phil.
They are official mascots for Illumination Entertainment.
