From the Splatoon manga (Coroika) world, Double Egg, the coolest X-Battle player!

This boy hasn't had much in life, other than being a victim of bullying in elementary school. Apart from being fashionable and being the third member of X-Blood, there are rumors that he is in love with Vintage, although the boy already has a girlfriend.

And his nickname is Dou.

Double Egg is an Inkling boy who wears Double Egg Shades, a Custom Painted F-3, and Amber Sea Slug Hi-Tops. He has the "Spiky-Haired" hairstyle, and he wields the Light Tetra Dualies. His hair color is aqua blue with a small amount of red at the tips of his tentacles, which is unique to him and his team. It is unknown what his eye color is, as he has never taken off his shades before, but it is very likely that his eyes are red like the rest of his team.
