Out of all the pokémon, that have shown up recently this one is confusing me the most.

[He tilts his gear up to show a sleeping Vivillon on his head for a moment before pointing it back at his face.]

Now, it isn’t the fact that its a butterfly or anything. I was excepting some sort of flying bug from the two bug pokémon, I was able to get last month. I’m calling it a Pixelfly for now, since that what those scales have been reminding me of. No this is what’s confusing me.

[He turns the gear the to the left and there is another Vivillon with a completely different pattern. I's sitting a counter, cleaning it's antennae]

When they evolved, they turned into these guys, but here is the confusing part. Either of one is a shiny, when they were just little Caterpillar like bugs, they were the exact same color. Yet here we are and for a split second I thought maybe it was a gender difference or area difference that caused it. But they are the same gender and they evolved at almost the same time. Yet here are the results.

Even weirder when I went to the pokémon center today, I saw another two, one with a pokéball pattern and another that was mostly white. How many different forms do these pixelflies have?
