This mega has been one of my favorite new megas (despite the hatred it's received recently) and I wanted really badly to at least reskin the OG mega lucario in a fangame I enjoy playing, but there were no pixel art backside sprites, party sprites, or sprites for the mega stone yet, and so I was impatient enough to try my hand at doing them myself!
The rest are mostly original, using the OG mega lucario sprite as a base for the party sprites, Recoloring a basic mega stone design, and rearranging the front facing Mega Z sprite for the back facing one.
I don't particularly think myself a visual artist since music is my thing but I hope these can at least prove useful to people who want to put the new mega lucario Z into either their own fangames or just to reskin things.
