FOR SCIENCE!!

And what is his creation? A shrink/growth formula, used by previous ponies that I have drawn, according to their pony gender. (male:shrink, female:grow )

Request *twitch* for on his OC pony Spark.
Basic thing you need to know of his OC is that he's a smart genius and stuff... OwO YUP!
Oh, and the mark he has on him is actually copied off of the deviation from guyperson13's gallery, made by for him [link] because I cannot make Cutie Marks. (hope this isn't a big issue ^-^) So yeah, original cutie mark work by Bpie.

Hope you like it, ; it was fun to pose him.
