Yoda (Earth-6457)

"Fear is the path of pain. Fear leads to anger. Anger leads to hate. Hate leads to suffering."

- - Yoda to Hal Jordan

Yoda is a Whill, and one of the leaders of the Green Lantern Corps, immensely strong on the force of Willpower. Unlike most of his kind, however, Yoda demonstrates a wide array of emotions, refusing to live a emotionless life, and displaying empathy and concern for others, instead of only thinking for the Green Lanterns.

Powers and Abilities

 * Whill Physiology: The Whills are living reservoirs of cosmic energy. Yoda has the ability to manipulate the emotional spectrum of energy that is willpower. The Whills formerly called this power the "Glow". Yoda generates this ability naturally and it is capable of all of the same effects as a Green Lantern power ring. This includes the ability to absorb and project great expenditures of energy as well as the power to create hard-light energy constructs. Yoda can also manipulate the emotional spectrum of energy that is hope.
