Tourian is an area in I Wanna Be The Guy that is based on the game Metroid. This area is very similar to the Tourian of the original game, as it has both the lava, and overall general appearance of it. The primary enemies in this area are metroids, just like the real Tourian. These metroids will appear if The Kid steps on certain areas, and will latch on to him to kill him. There are other enemies, however, that appear in room to obtain the secret item. These enemies include zoomers, and skrees. The boss of Tourian, just like Metroid, is Mother Brain. After the defeat of Mother Brain there begins a countdown, in which the The Kid must escape, or else he will die.
