Suddendath Beta was part of the endlessly reviving army of Shocker in the amusement park Game World. Emerging as a result of Kuroto Dan's plot to revive himself, they would persistantly attack, no matter how many times defeated, the Kamen Riders he had gathered for this purpose. Once the Game World was destroyed by Kazuma Kenzaki's Joker Undead power, the Shocker army was assembled one last time under Kamen Rider Genm Zombie Gamer and Totema, but was ultimately wiped out by Kamen Rider Ex-Aid Maximum Gamer Level 99 and the second Kamen Sentai Gorider.
