Marshadow is a legendary scorpion Pokemon and is a Poison/Dragon type. It has a reverse Protean like ability where it turns into whatever move type it was last hit with. In the post game there is a way to combine all 3 legendaries (Solgaleo, Lunala & Marshadow) into a manticore. You use this to defeat Zygarde complete form which was taken under control by an ex-team skull grunt that went rouge.
