Tuxedo Mask
Mamoru also demonstrates a spiritual connection with Usagi: he can detect when she has transformed into Sailor Moon. Early on in the anime series, before they become friends, this connection forcibly transforms Mamoru into Tuxedo Mask so that he can protect her. In later episodes, he seems to have control over his transformations, although he still shows up shortly after the start of most of the battles, no matter how far away from the developing situation.
