Explaining that his reasons are motivated by his desire to venture into the unknown for the sake of human evolution, Gamou transforms into the Sagittarius Zodiarts in front of Kamen Rider Fourze and defeats both him and Kamen Rider Meteor easily before turning towards Ran who has negated her transformation. When Ran states her intent to fight him, and seeing that the Pisces Switch is undeveloped, the Sagittarius Zodiarts decides to leave and bide his time for her to decide if she would wish to venture or die with the unworthy.
