This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Maero (Maori)
In Maori tradition, the Maero (or Mohoao) are an iwi-atua or supernatural people from New Zealand. They are sometimes described as giants or wild men of the woods, and inhabit mountains and forest, particularly in the South Island and Tararua Range. Maero are characterised as wild, malevolent and often violent, carrying stone clubs as weapons.
They are covered in dark body hair and have long, bony fingers with sharp fingernails. They kill and eat humans and other animals. The Maero are said to harbour anger towards the Maori, who arrived from Hawaiki, and are thought to have displaced them and ruined the tapu of their homes, forcing them to dwell in inhospitable alpine regions.
