Sometimes if Ben battles some tough enemies like a robot of something he knows that he doesn’t always need a heavy hitter because all he needs is a alien that has a big appetite. A friend of Max named Xylene unlocked this alien. This alien’s name is Upchuck.

Species and Home planet: Upchuck’s species is both Perk Gourmand and Murk Gourmand and where both species come from is a planet called Peptos XI (which was destroyed but his species did move on to a new home which I think is know called Peptos XII). See image of planets below:




Perk Upchuck Description (OS and Omniverse): Upchuck in his Perk form can be described as a bright green humanoid frog with green skin, six sprout-like growths on the back of his head, a dark-green patch of skin on his head, light-green skin on his face, a big belly, and crooked overbite teeth. He has some whisker-like lines on his face and also has a curled green tail. When he appeared in the Original Series as Perk Upchuck, he wore a black open-front suit with white over-sleeves, white bands around his legs, and white padding under his three-toed feet. Also the Omnitrix symbol was located on his right hand. When used by 11-year-old Ben in Omniverse, Perk Upchuck did look almost the same as he was the original series, but now his eyes are green and the Omnitrix symbol on his left hand is now green as well. He now has bare feet with short claws. When 16-year-old Ben in Omniverse used Perk Upchuck closely resembles 11-year-old Perk Upchuck but without clothes and the New Omnitrix symbol is located on his stomach. See images below:

Merk Upchuck Description (AF, UA, HU, and Omniverse): His Merk form can be described as a humanoid bullfrog with swampy-green skin, a tanned stomach and muzzles, black digits and black-green spots on his tail, limbs, and hips on his back. His eyes are now sharper than they look and they are pupil-less and green. He also has the same whisker-like lines just like his Perk form. His teeth are now more aligned with some visibly sharp canine-like teeth. When Merk Upchuck appeared in Ben 10 Generator Rex Heroes United, the black stripes on his face are longer, reaching his mouth, he only has two lines instead of three, and his claws are attached to his hands through finger stubs. When he appeared in Omniverse, he does resembles his previous design from Alien Force and Ultimate Alien, except that the claws are longer and bigger, the sprouts are brighter, and there are less spots on his body. He has only two teeth that are in the shape of an under bite. The markings on his face are also thinner and contained by the face and are no longer spanning the head. The Omnitrix/Ultimatrix/New Omnitrix symbol is located on his stomach. See images below:

Ben 23 as Perk Upchuck (Vomit Man) DescriptionWhen Ben 23 from an alternate dimension used his version of (Perk) Upchuck a.k.a Vomit Man, his looked the same as 11-year-old Ben’s (Perk) Upchuck except, and his has very different colorizations. Like for example, his skin is more bluish, the white parts on his outfit are light blue, and the black parts have dark blue highlights. See image below:



Mad Ben as Perk Upchuck DescriptionWhen Mad Ben used his version of (Perk) Upchuck; the color scheme of the skin looked more of like the skin color scheme looked that of a Merk Gourmand. The teeth of Mad Ben’s (Perk) Upchuck are mirrored, he wears a black helmet with a spike and orange glasses on it, has spiked shoulder pads that are connected. He has orange bandages around his wrists and orange colored spikes on the shoulder pads. The strap connecting the pads goes around the Omnitrix symbol, which is on his chest. Also the eyes and Omnitrix symbol are an orange color. See image below:

Special Abilities: In both of his forms Upchuck their first ability are the four very strong, adhesive tongues that can really stretch up to great lengths that allow him the ability to latch onto large objects and reel them in with relative ease. Their mouths can really stretch which allowing both Upchucks to swallow objects larger than themselves. Their species are connected with a trans space bladder dimension where all the “food” they eat is stored. Also both Upchucks are connected to the gourmand species and sense any danger to their people through their stomachs. By breathing air out of their mouths, both Upchucks show that their second ability is being able to fly. The third ability of both Upchucks is the items that they ingest which are converted into explosive balls of liquids that can be expelled with great accuracy. What Perk Upchuck does to these explosive balls he spits out when he’s ingesting food is that he can make them curve like a boomerang, shuriken, or a Frisbee. Murk Upchuck hasn’t shown to have the same ability as Perk Upchuck does. In his Perk form Upchuck can take a surprising amount of punishment for a creature of his size, like taking the force of a moving car impact as well as surviving after getting thrown through a wall. Both Upchucks eat and spit out energy, such as lasers, in the same way as they eat and spit out acid matter. In the episode Duped, it is shown that Murk Upchuck can spit out slime but Perk Upchuck hasn’t displayed that kind of ability. In Heroes United, Murk Upchuck was shown to be capable of eating Alpha’s containment ball. This demonstrates that both Merk and Perk Upchucks have very strong and durable tongues with are strong enough to carry Alpha’s containment ball, which weighed about 10 tons. Upchuck’s species are shown to be somewhat very quick, considering their small size. See images below:

Weaknesses: Both Upchucks weaknesses are the objects they swallow because they have a limit to how many big objects they can swallow at once. Both Upchucks can become very slow when they eat a lot of things and because when they do they become excessively fat. In the episode Evil’s Encore, when Perk Upchuck ate a chair with earwigs on it he suddenly felt the urge to spit out what he just ate because if he didn’t he was going to explode so that means he needs to find a place to spite it out very quickly. In Ben 4 Good Buddy, it is revealed that Perk Upchuck cannot consume the food that we eat on earth because his species eats the bad stuff so it’s hard to digest the good stuff. As it was revealed in the episode A Fistful of Brains, Perk Upchuck can’t swallow Ultimate Albedo’s energy beams that he fires from his third eye because they aren’t really good to ingest.
