"I will rid the Earth of self-serving humans!"
Thetis is the eternal younger brother of the Aesir group, known for his compassion toward animals and other living things. A genetically engineered superhuman, or "Mega Man", Thetis was made to be able to endure in extreme environments, in particular the crushing depths of the sea and the deep arctic regions of the Earth. Raised in seclusion within a series of Black SHIELD laboratories, Thetis trained with his family to become supremely effective killing machines. Thetis in particular took to the study of wilderness survival, as he was capable of operating in a combat capacity for incredible lengths of time without food or water. Like his brothers and sister, Thetis is extremely well-educated, with his specialties being in biology and ecology. His interest in the Earth is due to his deep-seated belief that humanity is destroying the Earth, and only by actively mending their ways can hope to save the planet. His environmentalist zeal can sometimes be disturbing. Thetis also acts as the Aesir team's medic, and takes a special interest in their diet and exercise to the point of nagging. Thetis is also the only Aesir who attempts to humanize Siarnaq, though these attempts usually backfire spectacularly.
