I'm terribly sorry for the horrible shading.
I was trying to experiment with the shading, adding more depth and all... But I guess I need to get out of my comfort zone and learn how to use something other than brush for gradient >>
I got pissed near the end and ended rushing with the shading. I don't regret one bit because yeah. Sorry for that but the sloppy painting is staying >>

Anyway this wasn't even part of my original plans. I saw the pose Mewtwo had in his new challenger picture and couldn't resist.
Yes the pecs were done that way on purpose.

Consider this a special celebration picture for Mewtwo's return to Smash Bros.
