Kyle Rayner is a
Green Lantern, not a Hybrid Lantern. He was the
last of the Green Lanterns after the destruction of the Green Lantern Corps in the "Emerald Twilight" storyline. He is also known for
briefly wielding the White Lantern power ring, which is a
combination of all the Lantern Corps powers but doesn't make him a "Hybrid Lantern."
Perhaps you are thinking of Parallax, the entity that took control of Hal Jordan and later corrupted Kyle Rayner. Parallax was a yellow entity, similar to a Yellow Lantern, that combined fear with green energy to create a powerful force.
However, there's no known comic where Kyle Rayner is definitively labeled as a "Hybrid Lantern."
