Suit

The Suit is one of the Flash's more unique villains, a sentient super-costume of an apparently supernatural nature it fought against DC's famous speedster.

History
Paul Gambi, tailor to supervillains, set out “to make the ultimate super-costume.” A man named Dell Merriwether got ahold of “The Suit,” embarked on a murder spree, and was stopped by the second Flash and Green Lantern. Electrocuted for his crimes, Merriwether vowed revenge, and the suit was incinerated. At least, that’s the official story. According to prison folklore, it had its own life, and could not be destroyed, hiding itself in the ground where a new wing of the prison would subsequently be built. Released by a seance, the Suit broke into the prison, killing two inmates and then taking over a small-time crook with a time machine. The Suit tried to kill the current Flash, succeeding in breaking his legs, then went on a rampage through Keystone, wrapping itself around one person after another, using their powers and draining their life, until it was stopped by the combined forces of two Flashes, Impulse, and Max Mercury.
