Gekkou

Gekkou is a Time Guardian who was recruited by TBS some time ago from his home planet of Subnixus.

He grew up in the country of Kerna, along with Rain Sulrai. Upon Gekkou's induction into the Time Guardians, he was given the elemental power of Air.

When TBS was hibernating in space once, Gekkou appeared to him and used his power over air to create an oxygen pocket around him so he could activate his lighter. He then used the lighter to reignite TBS, waking the Living Star from his slumber for the purpose of asking his assistance in vanquishing some more dangerous threats to time. TBS declined, as he needed to rest further to regain his power, but wished Gekkou good luck. With that, he disappeared, and hasn't been seen since.
