Millie/History

Past
Not much is known about Millie's childhood, except that she was raised in a large family in the Wrath Ring by Lin and Joe. In those years, she participated in Pain Games of the Harvest Moon Festival where she killed other contestants on at least one occasion.

At unknown points before the start of the series, Millie left the Wrath Ring, briefly dated Chazwick Thurman, met and married Moxxie, and joined I.M.P.

NOTE: The events depicted within the episode are confirmed to be not canon to the main Hazbin Hotel franchise by the creators. Millie is in the I.M.P Headquarters meeting room discussing how to improve the company. The group begins to argue and Eddie belittles the them, but after learning Eddie was indeed the target they take great delight in killing him.
