The Ragnarok Stadium (ラグナロクスタジアム, Ragunaroku Sutajiamu) is a stadium located in the future.
The Ragnarok Stadium was created by the Second Stage Children, with the ruins of El Dorado's headquarters, which they destroyed. A tournament was organized there, called the Ragnarok Tournament. The Second Stage Children's teams fought against Raimon and El Dorado, which were now allied with each other.
The three first matches ended with Zan's victory, Giru's defeat and a tie between Garu and El Dorado Team 03, being a tie for the two organizations. The last match, opposing Chrono Storm, also known as the Ultimate Eleven, to The Lagoon, ended with Chrono Storm's victory.

- In Norse mythology, Ragnarök is a series of future events, including a great battle foretold to result in the death of a number of major figure (e.g. Odin, Thor, Loki, etc.). In this case, it determines who will become the world's leader between Feida and El Dorado by playing three matches.
