I like this couple! Though possibilities cross my mind. Rouge teases Knuckles, right? Well, what if she takes it too far? What if Knuckles becomes so enraged that he hits her?!
About a 5/10
Edit: 2020
I still really enjoy this couple! Knuckles is always being teased, and I think Rouge likes the challenge of the Master Emerald. If they were to settle, I think Rouge would find it hard to adapt to his nature and live on Angel Island full-time, but enjoy every second of it.
And she's make a hell of a good mother <3
