For the stomping attack, see Ground Pound.

The ground pound[1] is a move that appears in the Sonic Boom series. It is the signature combat move used by Knuckles the Echidna and the reason why he is feared on the battlefield.[1]

When performing the ground pound, Knuckles delivers a punch directly into a surface (usually the ground). This attack is powerful enough to shatter a gigantic asteroid in space to pieces with a single blow.[2] The force from this attack creates rippling shockwaves of destruction which can send surrounding enemies like Ballot Stuffer Bot and Badniks flying.[1][3] Over time, Knuckles has demonstrated enough skill to induce the ground pound in rapid succession and with minimal effort.[4]

When using the ground pound, Knuckles can control which targets the ground pound affects to a degree, allowing him to sent specific objects flying with the shockwaves while those caught in their wake are only mildly affected.[5] However, the ground pound does not affect targets that are too big and heavy.[6]

"Knuckles’ Ground Pound: Here’s some sweet concept art of Knuckles’ signature combat move, the ground pound. It has the ability to create rippling shockwaves of destruction which send his enemies flying. It is the reason why Knuckles is so feared on the battlefield… and also why he is no longer permitted inside the library."
