Gotch (ガッチ) is an enemy found in Chaotix's Speed Slider. When the players reach a certain position in the level, it will come in from beyond the screen and land above the nearest player. If he grabs you, you will be surrounded in a green ball that will suck away your rings one per second. When this happens, it only can be destroyed by the other player, as he follows the movement of his victim.
