Anyway story behind this, Sonic and Amy head to the Deep Core Zone to find the final chaos emerald, much to their dismay, Eggman Nega awaits them both and sets the Volcano to erupt with no escape for them both.

Sonic tells Amy to escape while she has the chance while Sonic tries to stall the doctor. Eggman Nega uses his Nega Wizard to pursue Amy after he finds out she has the last Emerald.

There's more but no spoiling this is all ya get.

Pretty happy with how I drew it..just Amy's arm kinda annoys me but I gave up after so many tries with how to fix it and BOTH of their faces...god I was trying to practice the expressions as hard as I could XD
Amy is wearing her winter outfit since the Core is actually very cold, just an FYI.

I do like this sketch I did, even tho it's part of the Comic so I'll color it soon :)
