One common cause of SLUDGE is exposure to organophosphorus insecticides (including parathion, malathion, and diazinon) or nerve gas, such as sarin. These agents phosphorylate acetylcholinesterase, thereby irreversibly deactivating acetylcholinesterase and raising acetylcholine levels and causing SLUDGE.
Every stone grants different abilities to its owner. The Infinity Gems (previously known as Soul Gems) are some of the most powerful artifacts in the Universe. Each one allows its owner complete omnipotence over one aspect of the universe: time, space, reality, mind, power, and soul. When all six are directly wielded together, nothing is impossible for their bearer.
In the comics they were described as the Infinity Gems, with the most famous of them being the green Soul Gem worn by Adam Warlock. In the Marvel Cinematic Universe, they are more commonly referred to as the Infinity Stones; of which the Mind, Space, Power, and Reality Stones have already been accounted for on film.
