Young Justice: Courageous-
Before u read the book, you'll need some background information about Revenge's world.
The third book in the Revenge series, based on Earth-16, dives into Red Revenge mythology. In order for u to understand, here is a brief story:
Samuel Grant lived happily in New York City. His father was the owner of Grant Industries, a large national corporation. However, even though he was CEO of one of the largest companies in America, Sam's father had little money. He was planning to change his status door signing a multi-million dollar secret contract with Bruce Wayne when he 'committed suicide'.
Sam, knowing this was false, and gathering information from Bruce Wayne and Batman (unaware the two were one) he managed to find his father's killer and put him in court.
However, the man was never convicted. Sam, furious the killer was on the loose, began work on a costume. His girlfriend Rose Walker quickly discovered his secret work and donned her own costume. Revenge and Vendicta were able to (with the help of Batman) arrest and convict Sam's father's killer.
Several months later, the man who murdered Sam's father escaped from jail and dressed up as the grim reaper, naming himself Reaper. Superman arrived at that time in NYC. Revenge and Vendicta, along with the Man of Steel were lured into a trap. Reaper threw toxic gas at the teen vigilantes and shot at Superman with a kryptonite beam. Rose (aka Vendicta) took the kryptonite beam and was exposed to the toxic gas. Reaper was arrested.
Shortly after this, Vendicta gained all of Superman's powers in minor degrees. X-Ray vision, she could see through objects up to an six inches thick. She had super human strength (50% Supes) and could travel faster than a normal human, but not at super-human speed. She also had full power of flight.
Sometime during their crusade against crime, a girl from Sam and Rose's school discovered Sam (and later on Vendicta's) secret ID. She was a computer whizz and helped them for some time before becoming an official hero: Watchdog.
After several months, Rose was forced to move, leaving Revenge alone. He had a short relationship with Sarah, but it didn't work. After a new villainess( Nightingale) appeared, a Robin-type character also appeared fighting her. A 12 jaar old boy who called himself Eagle. He was killed in a battle with Reaper a maand after he joined Revenge.
Revenge was alone until the JLU discovered him and took him in. He worked on undercover missions for them for a jaar before joining the Team. The rest u have/will read.
Hope this helps! New chapters starting volgende year!
