Thunder Struck (あめのスカイサーキット lit. Rainy Sky Circuit in Japanese) is the ninth race course in Crash Nitro Kart and the final race track in Fenomena. It features huge trees, many jumps and it always rains. It is a difficult track for most players because there are no shortcuts and there are numerous obstacles the player has to avoid, such as the spiked swings. In the GBA version of the game however, the track is less detailed, featuring no trees except for the ones in the background, no rain, but still has many jumps. After time passed, road palette, sky background and everything will change color (only in GBA version of the game). It is used in the Aku Cup and the Purple Gem Cup (along with Android Alley and Tiny Temple).
This track returned in Crash Team Racing Nitro-Fueled.

- Originally, the name of this track was Head N. Clouds and lacked its rain storm theme.
- This track can be compared to Hot Air Skyway from Crash Team Racing, as it has a similar design, with the only differences being that there are no shortcuts, rain and statues.
- As the loading screen image is flipped from left to right, N. Gin's missile appears on the left side of his head instead of the right side.
- In Nitro-Fueled, Nitros Oxide's time trial ghost starts a few lengths behind the player.
