G.U.N. Hunters are humanoid military robots that appear as enemies in various Sonic games. They are tall, imposing and look rather blocky. Their heads are small with only a single optic light. There are several Hunter variants that carry different weapons including rifles, lasers and riot gel that can immobilize targets. Some Hunters also carry large shields to repel attacks, though Sonic and Shadow are capable of sliding beneath these shields.
