Scorpion

MacDonald "Mac" Gargan was a failing private investigator that was turned into the Scorpion with financial help from J. Jonah Jameson. He became a host of the Venom symbiote and was part of Norman Osborn's Dark Avengers. After the US Government took the symbiote, he became The Scorpion once again.

Mac Gargan was mutated to possess the proportionate abilities of a Scorpion and outfitted with a power-suit to further his new Scorpion persona. Without the suit, Gargan possesses superhuman strength enabling him to lift 15 tons, as well as superhuman speed, endurance, and reflexes that exceeded Spider-Man's. His suit provided him with increased durability, pincers on each hand that could tear through Spider-Man's webbing, and an extremely powerful cybernetic tail. Scorpion used his prehensile tail as for both practical purposes and as a deadly weapon. At times, his tail has been given certain additional weapons, such as acidic sprays, electric blasts, or a poison-tipped blade.

After his return as Scorpion, Gargan was fitted with a new much larger suit which is cybernetically wired into him. It is equipped with a more powerful tail, mechanical pincers, and is bulletproof. Gargan's biology was also altered, giving him a "scorpion sense" to match Spider-Man's "spider-sense".

For a time, Norman outfitted Mac with a Scorpion suit while the Venom Symbiote was recovering from injuries sustained in a battle with Anti-Venom. This Scorpion Suit provided added protection from Anti-Venom, allowed Venom to regenerate, and possessed a cybernetic tail/stinger loaded with a super-venom capable of killing Anti-Venom.
