Hariet

Harriet is one of the Broodals that can be fought in Super Mario Odyssey. Her only revealed battle is seen in the mission "Inverted Pyramid Showdown."

Inverted Pyramid Showdown
In the battle, Harriet is wearing a spike helmet, preventing Mario from jumping on her, and tries to throw bombs at Mario. Mario must use Cappy to reflect the bombs back at her to remove her spike helmet, making her vulnerable to be jumped on. After being jumped on, Harriet will fly around in a saucer fashion dropping down a number of bombs, which will lead little lava piles after blowing up, before finally landing and resetting the cycle.
