Because of the DNA of the Atlas moth and the added Sodium, what could have been a normal Skywing was totally changed. While Atlas’ body retains the average Skywing look, besides being overly large, his wings now more resemble a moth, even gaining an extra set, they are still scaled but have the shape and flexibility of a moths. He also has a pair of antennas which sprout from his forehead on either side of his head. He has also gained some of the patterns commonly seen on the Atlas moth.
Colors: Because of the added Sodium his colors differ from other Skywing in that they are mostly silver, with the exception of the patterns on his back and wings being red. The colors on his wings are similar to the body but as they go on the light gray turns a darker color with the edges being red in color. They also have noticeable red spots though a lighter red then the edges. His eyes are dark gray/ black
Na-404 is usually insane and slightly aggressive towards others the only deviation in this behavior is when he is around Subject At-210, also known as Nickel. When around Nickel he is rather docile, and while still being slightly aggressive, he is much more cooperative with the scientists. But to do experiments on Subject At-210 they must be separated as Subject Na-404 becomes extremely protective of her.
Nickel has taken to calling Subject Na-404 Atlas and he will now only respond to this name
