Ryan Wilder (Earth-4125)

"You want to know who I am? I'm the last glimmer of crimson a killer sees before he draws his final breath. I am vengeance. I am the night. I am the Red Death."

- Red Death to The Flash

Ryan Wilder, better known as the Red Death, is a vigilante in an alternate timeline and later an enemy of The Flash.

Early Life
In an alternate timeline where Bruce Wayne was never born, Ryan Wilder was adopted at mere days old by Thomas and Martha Wayne, who were both later murdered in an alley. This murder led Wilder to become a vigilante in Gotham City, better known as the "Red Death".

Hero of Earth
For ten years, Wilder, as the Red Death, locked up the dregs of society in Arkham Asylum, including Hush, Simon Hurt, and even her own brother. However, their imprisonment did not hold them, as they escaped Arkham over and over again. Wilder then began studying the weapons of her enemies, designing a series of weapons with Wayne Technologies resources. Eventually, Wilder's studies expanded to her teammates in the Justice League, including The Flash.

Rogue War
Mining data from The Flash Suit, Wilder was able to create an Artificial Speed Force for herself and made an armor to contain the power. With superhuman speed, Wilder became capable of capturing a criminal before they could even commit the crime, essentially eliminating crime from Gotham City. The Flash then released his own enemies from Iron Heights Penitentiary, working alongside them to take down Wilder and starting a Rogue War.

During the war, Wilder was held dead to rights at one point, with her mindlessly throwing a lightning bolt to defend herself. Unfortunately, the bolt accidentally hit Iris West-Allen, her best friend, and killed her. Wilder then evaded to the Speed Force, though was ejected out of it due to her inorganic speed and was stranded in a different timeline where the Ryan Wilder of the timeline became Batwoman.

Restabilization
Upon her arrival in the different timeline, Wilder's body was destabilized, and she was unable to stop her cells from vibrating. Wilder hired several criminals, including Captain Boomerang and the Fiddler, to steal parts for a machine which would restabilize her, giving them improved weapons from Wayne Technologies in return. On February 1, 2023, the first such part, the power source of Kord Industries' Roemer Accelerator, was successfully acquired by Captain Boomerang and was given to Wilder at her lair.

Next, she sent the Fiddler to retrieve Hartley Rathaway's Sonic Gauntlets. This resulted in failure the first time, which Wilder responded to by threatening Wozzeck's life if she failed again. During her second attempt, Wozzeck was defeated by The Flash, but was teleported away with the gauntlets by Captain Boomerang. With both components in their possession, Mercer activated the machine and successfully restabilized Wilder's body. She then sped across the city to a rooftop, where she swore to make Central City pay the price for The Flash's actions.

Identity Revealed
Hoping to assemble her Cosmic Treadmill to return to her home timeline, Wilder sent Mercer, Wozzeck and Michelle Amar to acquire the Temporal Scanner from Corbin Taft Industries. Wilder later recruited Mark Blaine to aid in the heist of the Quantum Vibration Engine from Fort L.U.K.I.A., unbeknownst to Allen's Rogue Squad. As the two groups of Rogues faced each other at the fort, competing to acquire the engine before their enemies do, Wilder arrived on the scene and knocked Allen's Rogue Squad on the ground, taunting Allen before extracting her own Rogues from the fort. Upon returning to her lair, Blaine demanded to know Wilder's identity under the mask, and she revealed her face to him.

The Flash Captured
With the construction of the Cosmic Treadmill completed, Wilder needed someone with organic speed to power it. Wilder then brought Roy Bivolo to the city and lured Allen out. Bivolo used his abilities to inflict fear in Allen's mind, allowing Wilder to create a powerful electromagnetic pulse that put the city in blackout and capturing Allen to her lair.

While Allen recovered from his injuries, Wilder surprised Iris West-Allen at her loft as her alternate timeline self. Despite her hesitance and confusion, West-Allen treated Wilder's injuries while she tried to determine whether she was telling the truth about her presence or not. Ultimately, West-Allen tricked Wilder in her own trap, as Wilder did not know that her alternate timeline self's adoptive mother was killed by the Wonderland Gang instead of the Royal Flush Gang. With her cover blown and being held at gunpoint, Wilder told West-Allen the truth and asked her to join her war against The Flash of her timeline, believing that West-Allen could talk him down. West-Allen questioned why Wilder did not ask her alternate timeline version, and Wilder revealed that she has accidentally killed her in a previous conflict. West-Allen refused to join Wilder, and Wilder summoned her armor from her lair to hold West-Allen hostage against Allen.

Reverse Flashpoint
At some point in an erased future, the Red Death attempted to kill Batwoman, but was prevented from doing so with a Velocity 0 gun created by Luke Fox.
