Gourmand

Gourmands (from "gourmet", associated with food) 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. Two sub-species of Gourmands have yellow eyes and at least three tongues.

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

Murk Gourmands wear metal saucers to protect their heads and fight with forks.

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

Perk Gourmands wear metal cups on their heads like helmets, and fight with spoons.

Queen Gourmand
The third sub-species of Gourmands is the Queen. So far she is the only example of a female of the species.

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 considered more thought-oriented and defense-minded, while Murk Gourmands are considered more action-oriented and attack-minded.

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, but have difficulty consuming organic matter. In addition, their tongues can be used offensively to throw objects or grapple an opponent. They've proven to be strong enough to pull down Incursean warships and heavy machinery.

After digesting something, Gourmands can vomit glowing spheres of acid that explode upon contact with considerable destructive power.

Gourmands can expel their breath downward in order to fly, using their belches like rocket thrusters.

Gourmands can survive in space as seen after they ate their planet, they propelled themselves through space in search of another.

They also 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 Gourmand representative is named Upchuck, and is available in both Perk and Murk variants. 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.
