Hailing from Asia, Gi controls the power of water.
Of the Planeteers' powers, Gi's is the only power that requires a nearby water source to be useful. Gi is a self-proclaimed marine biologist. Her compassion for sea life contributes to the overall effort of the Planeteers' protection of animals, becoming extremely emotional when pollution affects them, especially dolphins (due to finding her dolphin friend dying from pollution as a child), and somewhat impulsive at times. She also often works on the mechanical and forensic aspects for the team, as well as being the most diplomatic of the group who convinces others to see reason and do the right thing. Gi can also be seen wearing a gold medallion around her neck.
Wheeler controls the power of fire.
He is exceedingly the most street-smart of the group, yet, while having his heart in the right place, tends to get himself into tight spots when acting impulsively; fittingly, he is sometimes a "hothead".
Linka has the power of wind. Linka closely studies bird life and therefore is extremely emotional when pollution or illegal hunting harms them (because she admired birds who were used in the mines to detect gas while growing up as a miner's daughter). She is a master of strategy and logic, as well as a computer expert.
