Archie sent Tentacruel and Maxie his Houndoom to make Ruby pay for spoiling their plans. Tentacruel slammed Ruby on the ground, while Archie confirmed Tentacruel grabbed Courtney, who betrayed Maxie by siding with Ruby. Wallace faced Maxie and Archie and attacked them with his Pokémon. Since they kept Winona hostage, Wallace surrendered and called his Pokémon back, while Tentacruel grabbed him with its tentacles and slammed him on a rock, causing serious injuries. Since Ruby and Sapphire joined forces, Archie's Tentacruel continued to battle..
Archie used Tentacruel when he was the Guile Hideout. He used his Tentacruel to hold Salon Maiden Anabel captive in order for him to obtain the Jirachi report from Factory Head Noland. Noland gave in and handed over the report and Tentacruel let Anabel go.
