NegativePro

Negative Shenanigans
In NegativePro's early Jonaverse days, he made comics depicting himself pulling off weird schemes around Jon-Prime and sometimes the other artists. Usually these schemes made absolutely no sense, such as going to outer space to escape Rosajon (Even though she lives there)

Booru Voodoo (Good-bye Humanity, Hello Sonic OC)
NegativePro was one of the earlier people to get afflicted with Booru Voodoo along with Winter. The curse transformed him into something he never wanted to be, a fluffy Sonic the Hedgehog OC. While he doesn't hate the Sonic OC community, he avoided them because he was afraid of being bullied and discriminated against due to being harassed for drawing them while he was in High School.

He also gained the power to control electricity and now fights crime in the Jonaverse along with Winter and the other artists as a BooruVoodoo Avenger

The Wandering Wooper
In a majority of NegativePro's comics, there is a Wooper placed somewhere at random. This is Negative's way of leaving a mark on his work, kind of like a signature.

The PC rescue
NegativePro wanted to do whatever it takes to free the other artists from the effects of Booru Voodoo, his first attempt was a team-up with ChillRae to rescue Aelita1234 from being trapped within Jon Prime's PC. Though they were successful, they were shocked to see Amanda as an aqua blue hedgehog with a black streak in her hear, proving that Booru Voodoo will always be in effect on the artists as she had inherited both Negative and Rae's curses as the price for being freed from her original.

Acceptance
Later after the rescue, Aelita offered to use her photoshop brush to turn Negative back into a human. The cyan hedgehog turned down the offer however not just out of fear that he may get trapped into a laptop for doing so, but also because he realized he was turned into a hedgehog by Booru Voodoo because of the trauma he had in high school because of being bullied for drawing Sonic OC's. With those in mind, Negative decided that he was happy the way he is and now plans to stay as a hedgehog even after the Booru Voodoo craze dies down. (If it ever does die down)
