Manabozho (or Nanabozho) is a trickster character known in many of the Anishnabe Native American tribes (such as Ojibwe, Potawatomi, Odawa, and Algonquin) from the Great Lakes area. He figures prominently in their creation story and is a culture hero.
Manabozho had a human mother and a spirit father, and sometimes takes the shape of a rabbit. He is often portrayed as somewhat humorous, especially compared to the Algonquin trickster Wisakedajak, who caused a flood that encompassed the world.
An interesting note is that the second part of his name, 'bozho' is used as a greeting in the Potawatomi language.
Manitou is how the Anishnabe and Algonquin tribes refer to spirit. More specifically, spirits related to balance, nature and life. It's is comparable to the Chinese 'Chi'
