Noa is a extremely intelligent chimpanzee. His green eyes and his ability to speak come from the ALZ-113,  a man-made cure for Alzheimer's, and the ALZ-113 is the thing that caused the pandemic and the death of 99% of humans 312 years ago. Noa is cautious at times, but brave and willing to do anything he can to protect his family, friends and those he cares about without hesitation. He and his clan call humans 'Echos', and they raise eagles from eggs to bond with them through a special song.
