The Grounder was a drill-based badnik with tank-like treads. Dr. Ivo "Eggman" Robotnik created a model of one, as well as Sonic and his friends, in his personal Egg Cave. When Eggman showed Dr. Starline the models that he created in his free time, the grounder model was one of the models seen.


A model of a grounder was one of the many toy models created by Eggman that he had stored in his "Egg Cave" on the Faceship.
