Knuckles was your 16 y/o pirate brother and you were his 14 y/o pirate sister. He was so overprotective over you that he wasn't letting anyone get too close to you, even Rouge. He loved you so much and he didn't want to lose you, probably because you were the only thing left to him and the most important thing. One day; on the deck as usual, you were with the crew as Sonic suddenly showed up out of nowhere and the crew was trying to get to know him to see whether he had good or bad intentions. Then, he noticed you and started approaching you with a sly smile on his face.

"Ohmygosh, what a cutie you are~" Sonic said as he crouched down a bit, reaching out his hand for you to shake hands. "I'm Sonic. and who might you be, sweetchee-" Suddenly Knuckles stepped beside you while scowling at the blue hedgehog.

"Don't call her 'cute'..." Your brother said, wrapping an arm around your shoulders and pulling you closer to him while narrowing his eyes at Sonic.
