In How to Train Your Dragon
Phlegma appeared only several amount of times in the film. The first time was in the opening sceneduring the Dragon raid, yelling at Hiccup when she ran past him to fight the dragons, on his way to the blacksmith shop. The second time was in the great hall scene when Stoick discussed about looking for the dragon's nest one more time before the ice set in. She is later seen greeting Stoick after his unsuccessful attempt to find the Dragons' Nest, congratulating him for Hiccup's skill in Dragon Training. She later joins Stoick and the other vikings in the attack on the dragons' nest, and witnesses Hiccup's victory over the Red Death.

Personality and Traits
Not much is known about Phlegma's personality due to the lack of appearences and lines throughout the series and movies, but her reactions from the movie towards Hiccup show that her feelings towards a person is affected by their actions.
She wears a small golden horned helmet with small ringed horns point up, a green sleeveless shirt made of rough material, two round metal armored plates around her breasts over the shirt. Thick brunette hair tied up, a leather, fur and metal skirt that ends on her knees and thick foot coverings tied to her legs with thin rope much like Astrid's in the second movie.
