Leo Ring is a transformation item of Gen Ohtori from Ultraman Leo.
The origins of the Leo Ring are unknown but it is known that it was with Gen/Leo when he first arrived on Earth. Since then he has used it whenever he needed to transform into his true form.
How to useEdit
Gen waves his hands and performs a punching motion with his ring fist, holding the arm with his free arm. He then shouts 'Leo' and a bright light is emitted from the eyes from the lion image on the ring transforming him.
