Two rats seeing who can become the bigger humanmurine fireworks show.
The one on the left is Explodent, created by  SwearInPencil.
I took a spoonful of liberty with this piece, as I didn't have much intel on the character. I was just going on context clues, and making a series of wishful guesses... I basically had 89% confidence that Explodent was a combustible lifeform, and 48% confidence that he could trigger a reaction at will and that it wouldn't kill himself... and 9% confidence that he could manipulate the explosion to be colorful and sparkly...
In reality, I have yet to actually witness Explodent doing the thing he's named after. We might have a Bombjackal situation on our hands, where we just get indefinitely teased with the idea of him exploding... Looking back, the blue balls I contracted from Bonjak might have been part of what inspired to do more stuff with my fuse-tipped gremlin...
