Doing another collab pic, once again with her covering the inks and colors, so I figured I might as well put in a -little- more effort and detail since I don't have to go over everything in pen.

Decided to draw something based on Knuckles' final battle in S&K, which is one of my favorite moments in the series due to how it's set up, as well as Mecha Sonic being a total badass and going super.

I'll post the colored version once it's finished.
