FIVE Over

FiveOver is a Powered Suit developed by Academy City. It is the "treasure" of Silver Cross and its modelcase name is "Rail Gun." It has the capability of utilizing railgun methods better than the #3 esper, Misaka Mikoto.

Appearance
It looks like a 5m long praying mantis. It’s has two arms, two legs and two sickles that can fold if needed to help it standing up. Translucent wings spread out from the armour. A large cylinder-like thing used to store lots of cannons rests on its back. Also, there’re shields on the front side of the front legs, with an artificial weapon placed between these two shields.

Chronology
Kuroyoru Umidori has Silver Cross's corpse placed in it in order to dispatch and automatically pilot all the powered suits. It later pursues Hamazura Shiage, Hattori Hanzou, Kuruwa, and Fremea Seivelun into a building and coordinating the attack with other suits.

Abilities
With its name referring to the third strongest of Academy City, its main line weapon is a Gatling Railgun. While its not truly known whether or not can FiveOver surpass the third strongest, Shiage thought, "Science and technology continue to improve, and the latest technology yesterday may no longer be superior today." FiveOver can use its wings to move fast enough to leave afterimages.
