From the Super Mario Wiki
The Lightning Cup (referred as the Thunder Cup in Mario Power Tennis and in the Mario Kart: Super Circuit and Mario Kart 7 instruction manuals) is a cup in the Mario Kart series, as well as Mario Power Tennis. Its first appearance is in Mario Kart: Super Circuit where it was placed between the Flower Cup and Star Cup. It is absent in Mario Kart: Double Dash!!, but since Mario Kart DS, it makes its reappearance as a retro cup with tracks from past Mario Kart games. Thus, the Lightning Cup's history as a nitro cup in Mario Kart: Super Circuit makes it the only cup in the entire Mario Kart series to be both a nitro cup and a retro cup. The emblem of the cup is the Lightning. It mainly features tracks from the Star Cup and the Special Cup, though Mario Kart DS featured a sole track from the Mario Kart: Super Circuit Lightning Cup and Mario Kart Wii featured a sole Flower Cup course. The length and difficulty of the courses in this cup tend to be on par with those in the Special Cup. In Mario Kart 7 and Mario Kart 8, the final track of the Lightning Cup is a past Rainbow Road, very similar to how Special Cup's final course is a new Rainbow Road. The table below lists every track in the Lightning Cup by course order and game installment.
