Due to both his anatomy and him being made out of ground meat, Meatwad has the unique and rather impressive ability to stretch his body into various shapes and forms, with the most common by far being a hot dog and an igloo (as seen in the intro to every episode). Periodically he will also squish and stretch into various shapes as required by the episode plot, such as a hand displaying the middle finger (while antagonizing passing drivers at the Carl Wash), a flower (while high on pills), a meat bridge, and what he bizarrely imagines to be the likeness of Wayne Gretzky (everybody else except Randy the Astonishing correctly identifies the shape as Abe Lincoln wielding a samurai sword).

In some instances, Meatwad has also been shown to be able to multiply into several smaller versions of himself should he be sliced in half. The duplicates that he spawns seem to all possess unique personalities that are very similar to the original. The duplicates have also been shown that while they are all in theory parts of Meatwad, they are shown to be smart enough to form what appeared to be a government-style group in which they would discuss various things and make decisions on what course of action that they should take.

As his body is entirely made up of meat, Meatwad is also depicted frequently as being invulnerable to most forms of attack, though he is briefly killed when shot with a shotgun in the movie. And has been shot in The Cloning, Kangarilla and the Magic Tarantula, and Working Stiffs, but he did survive, but he did kill himself with a gun in the end of Grim Reaper Gutters.
