So, I decided to line and colour another artist's stream sketch. This time around, I went a little overboard with the variants I made along with the original sketch.
I figured that I could probably make some kind of story with the kind of stuff I did, so I just imagined that (in a similar vein to one alternate ending of Super Adventure Rockman) both Mega Man and Roll, along with everybody on Earth, was being erased from existence by some outside force they couldn't stop. So, I guess since this is the last time she'll see her big bro/fellow robot, Roll tearfully gives him one last smooch on the cheek in their final moments of life.
Odd thing is I originally imagined that this would've also taken place near the end of Megaman 3, after Rock's fight with Wily, and what with him getting crushed by debris, he'd finally wake up in Light Labs, where the following cheek-smooch would take place, since Roll's instead just happy he's alive.
