These two papercrafts are Purple Minions, originally Gru's Minions before Eduardo kidnaps them, and uses a serum (PX-41) that Eduardo stole from a top-secret lab, a mutating chemical compound, which transforms them into vicious, mindless, destructive monsters, that are completely indestructible, and will eat anything in their path, from the computer-animated 3D family comedy film Despicable Me, the paper models created by Julius Perdana.
The Evil Minions are very different from regular Minions, having purple skin, long arms, wild bushy purple hair, and crooked teeth. They are also wild, and don't usually speak, as much as scream most of the time.
Fortunately, Dr. Nefario created an antidote and mixed it in with the awful-tasting jelly Gru was developing, and utilizing a rapid fire delivery system, returning all the transformed Minions to normal. Even so, a single Evil Minion roars in front of the camera just before the credits roll.
The Purple Minions, are, for all intents and purposes, indestructible, as one of them was hit with a flamethrower and a gun, and was unharmed, struck with an axe and a police car, with no damage, and even swallowing a bomb and containing the explosion with no problem. [Source: wikia]
