Nola

ノラ
Nola, known to many as the Master of the Sky, is a giant snake who lives on Upper Yard in Skypiea. Having lived for over four centuries, the snake was once the companion of Kalgara and Mont Blanc Noland back when Upper Yard was still part of Jaya. It is the grandchild of the snake Kashigami, whom the Shandia once worshiped as a god. (Source: One Piece Wiki)
