In 2010 I participated in a comic battle on DeviantArt called PBCB2, involving the use of fictional original characters fighting each other using Pokemon(set in the Pokemon universe). The idea is to match people together, have them draw comics with the characters fighting each other, then a panel of judges decides who did the battle best, and the winner goes on to the next round until there is a single winner left.
I used to roleplay a lot with my friend Bully Birdy(again, set in the Pokemon universe), and had a bunch of original characters, which I included in my PCBC story.
The main character is nicknamed Shock, short for Shane Evans. See the comics in their original setting on Deviant art here.
CW: violence, swearing...
Shock's intro comic
A warning, these pages are very vertical... hehe, be prepared to zoom!
I did not win PCBC2, Shock made it to round 3 before I was eliminated by Zaifon. Zaifon's comic was so freakin' amazing, you can see their side of the battle here.
