(Collab Story With KaijuMaster20 and worldofcrossovers517)

Description: Nancy Oleson Howard was freed from prison, and develops a new plan to exact her revenge on her stepson Percy Howard. She created a new symbiotic monster known as Project: Apocalypse. Making things worse, she has the backup of three Time Jackers who became Another Godzilla, Another Virgul and Another Birthright. Also, a new Ultra came into the picture, leading an army of aliens known as the Nebula Beasts. Luckily, Percy and his new ally Titanus Athar will count on old allies like Ryuko, Satsuki and their friends, and new allies like the Hyperdimension Forces, Daikaiju Knights, Force Impulse Gundam and Kamen Rider Ryuki. Will they be enough to prevent the imminent apocalypse?
