All Riders vs. Dai-Shocker
Longhorn Orphnoch was part of the advance guard of the Dai-Shocker army in the World of Decade, led by General Jark. They appear to pursue Diend and Natsumi before they are confronted by Tsukasa who transforms into Decade. When the grunts are defeated, the Longhorn Orphnoch tries to protect General Jark alongside Ganikomol and Leiurus Acutia, but to no avail as all four are destroyed by Diend's Dimension Shoot.
