17 year old Perk Upchuck closely resembles his 11 year old form without clothes, he also has the Omnitrix symbol on his "nose".
In A Future Enemy, Perk Upchuck now gains an outfit similar to his younger form, except in green. The Ultimatrix MK10 is now on his chest.
Upchuck has four very strong, adhesive tongues that can stretch to great lengths, allowing him to latch onto large objects and reel them in with relative ease.
Upchucks mouth can stretch, allowing him to swallow objects larger than himself. He is connected with a trans-space bladder dimension where he stores all the "food" they eat. He is both connected to the gourmand species and sense any danger to his people through his stomach.
By breathing air out of his mouth, Upchuck is able to fly.
The items ingested are converted into explosive balls of liquids that can be expelled with great accuracy. Upchuck can also make them curve, like a boomerang, shuriken, or frisbee.
Perk Upchuck is able to take a surprising amount of punishment for a creature of its size, taking the force of a moving car impact as well as surviving after being thrown through a wall.
Upchuck can eat and spit out energy, such as lasers, in the same way he eats and spits out acid matter.
In A Future Enemy, it was shown that Perk Upchuck can swallow and spit out fire balls. No other Upchuck has displayed this yet.
Perk Upchuck has a limit to how many big objects he can swallow at once.
