Gi is from Asia, and the eldest of the Planeteers.
Her power ring grants her some control over Water. Gi is a marine biologist and has proven to be quite agile , so much as for Kwame to say she gets a ten doing gymnastic like moves.
She can control water from any source, be it a well, faucet, river, or sea. She can even call the ocean to do her bidding, calling up large waves or tall strong water spouts. She often calls upon small water sprouts from various sources, but she has proven to move large amounts of water across a large span.
