Kamen Rider 555: Paradise Lost
Accompanied by the Wild Boar Orphnoch and the Pelican Orphnoch, the Slug Orphnoch walked in on Kyoji Murakami's conversation with Yuji Kiba and the renegade Orphnochs office. The three asked Murakami for permission to kill Kiba, calling him a "traitor" to the Orphnochs for associating with humans. The Slug Orphnoch then assumed his Orphnoch form along with his companions to deal with Kiba but Murakami summoned Leo and told him to go kill them to demonstrate his powers. Leo transformed into Kamen Rider Psyga and destroyed both the Wild Boar and Pelican Orphnochs with his Phone Blaster Burst mode, causing the Slug Orphnoch to run away. However, Psyga chased him down and killed him by snapping his neck.
