Leo Imagine
The Leo Imagin is Kai's subordinate and uses his three Leo Soldiers to kill Momotaros, Urataros, and Kintaros in the Time Station while he handles the task of killing R-Ryotaro Nogami upon fulfilling his part in Kai's plan. But Yuto Sakurai drives the Imagin away with his attack and Momotaros, Urataros, and Kintaros use their versions of Den-O's finishers to destroy his Leo Soldiers. When Den-O Sword Form appears, the Leo Imagin travels back in time through Kai with Den-O in pursuit. But before the fight could start, Momotaros loses his sync with Den-O, leaving Ryotaro to assume Liner Form and fight the Leo Imagin, using the DenKamen Sword's RyuGun Mode to destroy him.
