Appearances in games
Crazy Party series
Grounder was one of the playable characters in the early Lunatic Entertainment game, Sonic Bomberman, released in 2001. He possessed average speed but could take two hits before dying.
Grounder makes an appearance in Sonic Heroes 2 as part of Team Badnik.
Grounder makes a reappearance in Lunatic Entertainment's Sonic Reunion, which features a majority of the Sonic characters across various media platforms in a gritty setting. Grounder is a member of Team Dark alongside Rouge the Bat, Shadow the Hedgehog, E-102 Gamma, Omega, Scratch, Coconuts, and his master, Dr. Eggman.
Grounder is one of the thousands of characters to appear in this 2D action battle royale. In the game his character is of the dual Saboteur/Die Hard class, with the former being a reference to his original appearance in Sonic Bomberman, and his latter due to his being an American slapstick cartoon character.
Although not particularly fast-moving, Grounder is able to damage any opponents that he comes into direct contact with from the front due to his drill arms and legs. He can become an Ally of Convenience with Dr. Eggman, who can repair him if damaged or destroyed. He also possesses an alternate costume that gives him the appearance of a regular Grounder enemy from Sonic the Hedgehog 2.
