Knuckles the EchidnaEdit
She and Knuckles have a strange relationship, them being rivals as treasure hunters, but then again Rouge tends to flirt with Knuckles, even calling him "Knuckie".
Shadow the HedgehogEdit
In Sonic X Rouge and Shadow first met when she was making a buisness transaction with Dr.Eggman. She showed intrest in Shadow, like she cared for him. In the last episode of Sonic X, when she was staring at the capsule she had found him in earlier in the season, Eggman said that she was worried about him, she denied this.
She and Amy have some sort of rivalry, and Rouge sometimes tends to tease her.
Rouge has shown a joy in teasing the young fox, as shown in the show where she kissed him on the cheek to make him lose a battle.
