Rider is apart of Team Yellow-Green, and the S4. He's not the sweetest Inkling of them all, but he can still have a pinch of it in him. He gets along more with the Yellow-Green team rather than with the S4. He doesn't show his emotions to others, but hides them. He does care for his teammates, even if they're not easy to get along with. He just doesn't show that much. Has a dark teal scar on the right side of his face and a bit of his ear due to Tartar.
