Scorpion's suit was his main weapon.
The suit was created by Dr. Farley Stillwell and given to Mac Gargan. The suit had claws on the gloves which allowed Scorpion to climb walls similar to Spider-Man. However, the tail was the most important weapon on the Scorpion suit. The tail was able to fire acid from the tip and there was a blade on the tip aswell. Scorpion also had complete control over the movement of his tail and would use it to hit or bind his enemies.
