Lex Luthor's Warsuit

Lex Luthor's Warsuit is a large body of armor built and used by Alexis Luthor, the archenemy of Superman from the comic book series with the same name. As Luthor isn't physically capable of even withstanding Superman's overwhelming strength, he built a power-granting exoskeleton that gave him the strength necessary of fighting Superman toe to toe.

Features
Malfactured by LexCorp, the warsuit granted him the strength and durability that could almost match Superman's, who could lift 200 quintillion tons with a single hand without breaking a sweat. It also granted him flight via some sole mounted rocket boosters and gauntlet launchers that shot electrical strikes and kryptonite beams as well as an energy blade and kryptonian energy spikes.
