Kodachrome, or Koda for short, is a protogen built by Yami. He is fascinated with landscapes, as well as the lives of people around town. He wanted to find a way to preserve life, so he uses his camera to take pictures of things he think are worth preserving. He's very caring, if not a little strict and by the books. He has the power to change the color of anything he touches with the tip of his tale, which resembles a paint brush. Koda has a great understanding of human and mortal life, and he is fascinated by little things that mortals enjoy. 

Kodachrome is a caretaker. He is more on the strict side, wanting everyone to be free to do as they please (as long as it's safe!), being the inverse of Saturn. The two clash a lot, but at the end of the day, they want to do what's right. 

Kodachrome loves wearing sweaters. Every time you see him, he's in a different sweater. In hotter climates or seasons, he simply ventilates the inside of his body so he doesn't overheat; and so he can stay wearing sweaters. Kodachrome's code was written entirely in JavaScript. Kodachrome is powered with a 3500mAh High Capacity Li-ion Polymer battery, meaning he has to recharge every night.
