Original Description:
 
Part 1 of a birthday gift i received from Astrum. Usually far smaller than him, looks like Fleetfoot got her hands on a particular device that will close that gap… and she knows he’ll enjoy it, breathe Calm… breathe!
 
Part 2 is here
 

 
There’s some context needed here: The belt Fleetfoot is wearing is a reference to an old comedic superhero cartoon called The Tick, in one episode, the lead’s meek, pudgy sidekick steals a belt off of a super villain, who abruptly shrinks down from a big muscle head to a skinny wimp. Turns out the belt makes the wearer bigger, stronger, and beefier the higher the dial fixed on it is turned… and it leads to shenanigans. Here is the episode
 
This concept has appeared in this older commission from Matchstickman who is currently working on and off with me on a comic commission that parodies the whole Tick episode
 
 
along with these i’ve done a lot of idea pitching and shared many rough photoshop edits with Match and Astrum and we’ve had conversations about the concept of the ‘muscle belt’ a lot, how particular characters would happen upon it, what their reactions would be, how things would get funny or interesting as a result…
 
So anyway, if this seems random, it makes perfect sense considering how much we’ve been talking about it over DMs.
 
thanks for the great gift Astrum!
