Their main body takes the shape of a long stream of floating bubble-like spheres which by themselves don't have to be connected to each other. The end of it's 'body' is a large spherical head with a circle shaped mouth full of jagged teeth, much like a tapeworm. On the its sides are two round compound-like eyes covered with geometrical pattern composed of black and white circles.
Like that of a worm, the Magic Worms have the ability to dig underground and emerge and posses great physical strength, being able to effortlessly seemingly kill Tezca Tlipoca by drilling through a body as well as pin and hold Mosquito as well as shoot a powerful laser strong enough to  These worms are remarkably fast and power, being able to defeat even DWMA's Elite staff featuring Sid Barrett, Marie Mjolnir, Franken Stein, Mira Naigus, and Tezca Tlipoca.
- The design of the Magic Worms are based on the Smoke Worms in which appear in the videogame Soul Eater: Monotone Princess.
