One of my created MLP characters, Shifthchange, a little unicorn colt who's practicing his specialty, Transformation and Transmutation. In this case he's a little tired of the same routine with carrots day in and day out, and so he'll reward himself for hard work and practice, making a cookie out of the carrot.
And for those curious, his mark is a combination of two alchemical symbols for purification. I figured it's the closest I could do for a pictorial representation for transformation.
