Alpha Rookey is a Dark element boss in the Russet Highlands. Here's where to find it, why Wind element Aniimo are the best pick, the attacks we saw including the flattened state, and how to catch it.

Alpha Rookey Weaknesses

Alpha Rookey is a Dark element Aniimo, so Light and Wind element attacks are Super Effective against it. Wind element Aniimo are the best choice: their attacks are Super Effective, and they also resist Alpha Rookey's own Dark attacks. The map panel agrees, listing Wind and Light as Highly Recommended and Rock as Not Recommended.
