I have short biographies written out for the black set during the Kickstarter when they were stretch goals. Not sure if anyone wanted them, but here:
Function: Smooth Criminal
" As he came into the window, it was the sound of a crescendo."
Alternate mode: Energy negating anti-sound ray.
Function: Speed Demon
"Nothin' gonna stop ne, ain't no stop and go."
Alternate mode: Faster than dark attack bow.
"Darkness falls across the land, the midnight hour is close at hand."
Alternate mode: Negative matter cleaver.
