Enter Wart the Wartoad

Enter Wart: the Wartoad!!!
This guy has been with me for years, dating back to 1995. That was the year I first played that Battletoads coin-op game. I fell in love with that game; I became addicted to the Battletoads franchise back then, going so far as to create my own Battletoad. I couldn't come up with a cool skin disorder for a name, but somehow the word Wart popped into mind. I know there's already a toad named "Wart" out there (Super Mario Bros. 2), but since I created this guy, I can name him whatever the hell I wanted to call him!!! Yea, one can guess this is rough work (being that this was drawn on notebook paper), but I'm currently vectoring this drawing, seeing if I can pull off the vectorwork.
At first glance, you'd think this guy was Pimple with spiked shoulderpads, but a closer look at him, this guy's wearing the Dark Queen's emblem (the Radioactive symbol), and he's got a small set of tusks on his lower jaw. To compare his size to the other Battletoads, he stands about 2 feet taller than Pimple (Pimple's last recorded measurement was 7'4").
The backstory for Wart is that the Dark Queen was desperate to create a weapon to finally destroy the Battletoads, and she opted to fight fire with fire by creating her own Toad. Somehow she was able to obtain genetic material from all 3 Battletoads. She then abducted an unlucky victim from Earth, strapped him onto the lab table, and pumped his body with the genomes of all 3 Battletoads. Her experiment was not yet complete as she brainwashed the prometheus into becoming an obedient Weapon of Absolute Destruction, now christened as Wart the Wartoad.
Now to give this guy his own skin coloration; Rash was dark green, Zitz was teal, and Pimple was a tannish brown. I don't want to give Wart a preset color scheme. I remember Zitz at one point had an olive-green color, so maybe I'll give him a grayed-out olive green color; I wonder how that'd look?
