Sonic the Hedgehog 2
- This page deals with the mass-produced badnik model. For more on the Adventures of Sonic the Hedgehog character, see Grounder (AoStH).
Grounder (called Handrill in the Japanese Manual) is a badnik in Sonic the Hedgehog 2 games in Aquatic Ruin Zone. Its colour is red and blue or red and gold. They mainly attack by breaking through walls in a surprise attack, much like the similar Burrobot enemy from Sonic 1's Labyrinth Zone.
The enemy reappeared in Sonic Pocket Adventure's Aquatic Relix Zone.
