Moowis originates from an Algonquin myth about a man who was spurned by the woman he loved. To pay the woman back for her actions he gave life to a snowman who became a beautiful warrior named Moowis; who he created by using forsaken scraps, the earth, and the last of winters snow to make his body. A song was sung by the man to the Snowman to give it life. The woman would fall in love with Moowis and he would take her as his bride.
Promising to share everything once they traveled to his home up north, the woman and Moowis traveled during the night at a fast pace bringing great harm to the woman's feet. On the last day with no shade or place to hide from the sun he would melt before her eyes. She then felt the pain of loss as he became water, with only his headdress and clothes left behind.
Moowis first appears when Carol J botches his summoning of the Great Angel Kokabel, where he possess the man's body and partially transforms it to fight the protagonist. After his defeat he leaves Carol's still living body behind and attempts to possess Hitomi, only to fail thanks to Nemissa causing him to flee.
He appears in his second form after the Protagonist talks with his family in the aftermath of saving Tomoko. Calling Nemissa a threat, he attempts to kill her with his body of steel. Surprised by how stronger she is after his defeat, he proclaims again that she is a threat to him and his master before retreating, leaving a piece of his metal body behind that makes it possible for the Spookies to track him down.
He believes Nemissa is planning to kill him and his master after the Spookies chase him down to the Auto Plant to get answers. Realizing she knows nothing, he attempts to kill her with his newest body. After his defeat he retreats into Paradigm X and into the VR Tour. He realizes she has truly lost her memories, and declares even with his death the second and the third will defeat her in his place, allowing Manitou to succeed. He finally dies after wasting all the power he used to enter the virtual reality.
