Prohyas' Stomach is the anthropomorphic stomach of Prohyas Warrior and minor antagonist who debuts in the Mighty Magiswords short, "Vambre's Brain" and made a major role in the TV series episode, Gut Feelings. He is voiced by Luke Ski in his debut appearance and Gilbert Gottfried in his second appearance.
Prohyas' Stomach appears on his shirt over his abdomen, materializing as an agitated face with green eyes and a large mouth.
Prohyas' Stomach, similar to Vambre's Brain, is loud, rude, insensitive and self-centered. He cares little for the well-being of others, only caring about what Prohyas' consumes. He speaks with a loud grating voice, and although a frequent schemer, is overall lacking in intellegence.
He appeared towards the end of short named after her where due to Prohyas' lack of food, caused him to snap at Vambre for interrupting his snacking time by shouting "DON'T BOTHER ME, LADY! I'M HUNGRY!!!!".
His major debut is in "Gut Feelings" where he was responsible for controlling Prohyas to steal all of Hoppus' vegetable magiswords in order to feed himself nutritious vegetables to counteract Prohyas' junk food toxins.
- Body Controlling: Like Vambre's Brain, he has the ability to control Prohyas' body.
- In his debut appearance, Prohyas' Stomach was voiced by Luke Ski doing a Gilbert Gottfried impression. In his second appearance, he was voiced by Gilbert Gottfried himself.
- Unlike Vambre and her Brain, Prohyas is unaware of his Stomach's activities, and the two do not converse with one another. Prohyas' Stomach is also visible and audible to other people, whereas Vambre's Brain is only visible and audible to Vambre herself.
