Argoyle & Ugoyle the Shisaroids

Argoyle the Shisaroid and Ugoyle the Shisaroid (アーゴイル・ザ・シーサロイド & ウーゴイル・ザ・シーサロイド) are two halves of the same Pseudoroid based on Shisas (ancient Oriental guardian statues resembling dogs or lions) that use co-operative tactics to defeat their foes by attacking from several directions. They are equipped with Dash Rollers, which enable them to travel at high speeds. Argoyle has an open mouth and rounded forehead gem upon his head, while Ugoyle has a closed mouth and a horn upon his. They use the Rock Bomb ('Aiguille Sphere' in Japan) to attack.

They are found in the Waterfall Ruins. Argoyle is the one who does most of the speaking while Ugoyle often responds in kind with grunts. The only things Ugoyle actually says in the entire game is "End of the line for you!", "DIE!", "Bombs Away!", and "Meet your end!". After Argoyle and Ugoyle are defeated in Ouroboros, Argoyle accepts the player as his "new" master as he says "We throw ourselves before your feet." while Ugoyle just grunts, possibly not accepting the player as his "new" master.

As a copied form, these two work in a slightly different manner. The player controls Argoyle, who can throw Rock Bombs and dash for as long as there is room. The player can also summon Ugoyle as a ghost to travel in front of Argoyle and kick enemies or Rock Bombs that Argoyle has thrown. This Ugoyle is not affected by terrain or obstacles and can retrieve certain out-of-reach items such as Secret Disks or Sub Tanks.

Trivia

 * Argoyle and Ugoyle's names and secondary motifs may be derived from the twin deities Agyo and Ungyo, known together as Nio, the twin protectors of the Buddha. Their names also might have come from the word "gargoyle", stone carved into a shape of an animal that rests atop roofs.
 * 'Aiguille' is French for 'needle'.
