Ork Kommandos: Bill-e and Bawby
Siege of Slawkenberg

Bill-e and Bawby were not in a good mood.
Korbul had just died, and the Waaagh! had broken up immediately. While they weren't the shootiezt of boyz, or the choppest, or the most kunnin, or the most brutal, they weren't the dumbest of boyz. The Waaagh! was done for, and Bill-e and Bawby saw an opportunity to book it in their newly acquired Battle Bawrge Da Choppa. As the sneaky gitz made their way to Da Choppa, they somehow managed to be followed by every zoggin weirdboy and mekboy left in the Waaagh!, despite being covered head to toe in the finest purple paint. That would turn out to be a blessing.

One day later
Bill-e and Bawby had just managed to escape Slawkenberg, though it was by the skin of their teef, due to the mekboyz taking their sweet time modifying and repairing Da Choppa. Thankfully Da Choppa was in Da Green Forest, and was painted purple, so it could never be found. That didn't mean the mekboyz and their scavenging parties couldn't be seen, so Bill-e and Bawby ordered them to paint themselves purple and to quick about scavenging. All in all, about 10,000 boyz left in Da Choppa.
Humies didn't know they was even there.

Six months later
A mekboy had just came up with a way to transform them into weirdboyz. They didn't know right how it was done, only that it involved injecting boyz with a specific color of green called jade that was mixed with a shiny yellow called gold. Right alkemy, that was.
