OCtober #30: THE LAST CROSSOVER! Okay, interesting story behind this one. These two were originally from a Powerpuff Girls fan-comic called PPG2. In that comic, the girls were using a system that scanned you to create an online avatar -- and that's what Trinette was. In their un-fandomed redesigns, I imagine that Trinette is an older cousin that Nellie wants to emulate.
