Armageddon (Earth-Prime)

"Bear witness to a coming Armageddon that you create ten years from now, one that destroys your own planet. It's already happened, Flash, that's why I, Despero, have to kill you. It's how I save our world."

- Despero to The Flash

Armageddon is the apocalyptic event that was caused by The Flash's enhanced superhuman speed, which led to the total destruction of Earth.

In November 2021, The Flash was encountered by Despero, who travelled from 2031 in order to kill him before he could cause Armageddon. However, Despero was thwarted by the duo of The Flash and The Atom. Eventually, The Flash was able to summon Despero to the Speed Lab and decided to understand his motives. The latter explained how The Flash's speed led to the planet's demise, while The Flash voluntarily allowed Despero to read his mind.

While Despero only saw honor in The Flash's mind, he chose to keep an eye on him, not letting any possibility for Armageddon to happen. Despero also informed The Flash that the entire event began from the day The Flash losing his sanity. Team Flash soon attempted to preserve his mind and discovered a telepathic Metahuman criminal, Xotar. The Flash successfully located her and was then affected by her powers, turning him against his team before they could restore his mind. Despero suspected that it had already begun and appeared in Barry's mind through a psychic projection, revealing his past and the reason he wanted to protect Earth.

After defeating Xotar, Barry returned to his team and proposed to have a meal at Joe's. However, they reminded Barry that Joe had died six months prior. Barry do not retain any memories of the event and sped to the West House for evidence. Confused, Barry was encountered by Despero, who attacked the team using the Flame of Py'tar. Chester P. Runk and Allegra Garcia arrived in the nick of time and bought time for Barry's escape. The latter sought refuge in the Hall of Justice, in which he met Jefferson Pierce.

Total Destruction
In 2031, Despero was banished to Earth after a failing to kill a oppressor on his home planet, Kalanor. However, as soon as he arrived on the planet in Central City, he witnessed The Flash running at an exceptional speed and cracked the Earth opened. Despero then travelled back to 2021 and attempted to prevent the apocalypse from happening.
