So you've met Hoshi, the father of Dysphox, but what about the father of Koráki? Well meet this fancy fellow!
Originally, Shadow just took pity on Sonic's situation after the unwanted fusion with Metal Sonic. But over time, satiating that uncontrollable libido became something more, and he actually grew fond of his rival. Repeated sessions would eventually result in Shadow getting pregnant, and giving birth to his powerful yet nerdy child.
To help control his Black Arms mutation, Shadow gave Koráki the inhibitors from his wrists, engaging in more relaxing activities to keep his energy from going wild. He is surprisingly submissive, as evidenced by the bedazzled day collar around his neck, and uses the huge collar as a pillow for quick naps whenever he's in the mood for one. The white half-socks around his feet aren't just comfortable, but useful for helping Sonic when needed. As for why there's a white stripe down his chin, it's also for a naughtier reason~
He is designated as Kage within my roster, but does not go by that as an actual nickname as Hoshi does.
