This was done when Sonic Adventure 2 was fairly new. I wanted to draw Knuckles and several characters who are associated with him: Rouge, Tikal, Espio, Charmy, and Mighty. Rouge seems to be teasing Knuckles, and Tikal is scolding her. I think I referenced Rouge from screenshots or action figure photos, not official promotional art, because her colors are different from what you usually see in the official art.

I probably meant to include Vector or other characters, but never did. I miss the days when the Chaotix included Mighty and were officially associated with Knuckles. In the games and Sonic X, they don’t seem to have much to do with Knuckles anymore.
