Alola is my favourite region. It was the first one I completed a dex for, the one I spent the most time in, and I absolutely adore it's starter trio. So, they will take up some of the last days of Mega Month, starting with the one I personally chose.
I liked the idea of Mega Decidueye manipulating several arrows at once, and I gave it a bunch of glowing segments, including it's one open eye that allows it to channel spectral energy. Plus, the greens are much darker.
