Gourmand

Gourmands are a species from the molten planet Peptos XII.

Appearance
Gourmands are small, frog-like aliens with short stubby limbs, four-fingered hands, three-toed feet, six tubular growths on the back of their head, and three sets of gill-like markings on their face. According to Derrick J, Wyatt, there are three different types of Gourmands.

The first is the Perk Gourmands, who are are green all over with a darker shade of green on the top of their head as well as all over their backs and hands. They have very crooked teeth that appear outside the top of their mouth, forming an over-bite.

The second is the Murk Gourmands, who are swampy-green with tan bellies and muzzles, black digits, and black-green spots on their tails, limbs, hips and back. Their teeth are more aligned with visibly sharp canine teeth that appear outside the bottom of their mouth, forming an under-bite.

The third is an unnamed race which their Queen belongs to. The Perk and Murk Gourmands both have yellow eyes and at least three tongues.

Behavior
Perk Gourmands and Murk Gourmands do not normally get along with each other, but will obey and protect the Queen Gourmand without question.

Perk Gourmands are thought-oriented and defense-minded, wear metal cups like helmets, and fight with spoons. Meanwhile, Murk Gourmands are more action-oriented and attack-minded, wear metal saucers as helmets, and fight with forks.

Generally speaking, Gourmands are not an aggressive race as their main thoughts revolve around eating. The mere mention of food is enough to distract Gourmands. Given the chance, a Gourmand will begin snacking on any kind of material in its vicinity.

Powers and Abilities
Gourmands are able to digest almost anything, including solid matter, energy, and even other lifeforms. After digesting something, they can cough out glowing acid spheres that explode upon contact with considerable destructive power. While Perk Gourmands have difficulty consuming organic matter, Murk Gourmands do not.

Gourmands can use their tongues offensively to throw objects or grapple an opponent. They have proven to be strong enough to pull down Incursean warships and heavy machinery.

Gourmands can expel their breath downward in order to fly, using their belches like rocket thrusters. Likewise, they can propel themselves in the vacuum of space, which also confirms they can survive in space itself.

Gourmands have great stamina for their size, such as being hit by a car, skidding across a concrete road for a decent distance, or crashing through a brick wall.

Omnitrix Transformation
The Omnitrix's Perk Gourmand and Murk Gourmand representatives are both named Upchuck. Perk Upchuck first appeared in the original series episode "The Visitor" after Xylene entered a code in the Omnitrix. Murk Upchuck first appeared in the Alien Force episode "War of the World: Part 1" after Azmuth unlocks the Omnitrix's Master Control. Between the two variants, Upchuck has appeared in almost every series except the reboot.

The Ben Tennyson of Dimension 23 has an equivalent of Perk Upchuck named Vomit Man, who was confirmed to exist in the Omniverse episode "Store 23" before eventually appearing in "And Then There Was Ben".

Perk Uphuck has also been used by Mad Ben, while Murk Upchuck has also been used by the Prime Timeline Gwen.

Etymology
Gourmand comes from "gourmet", a term associated with food. The subspecies "Perk" is named as a homage to Tom Perkins, a character designer in the original series. The subspecies "Murk" is named as a homage to Glen Murakami, an executive producer for Alien Force and Ultimate Alien.
