Radaxian Castle

The Radaxian Castle is the home of King Thunder and Prince Igul, located beyond the Bingoo Lowland and the forests of Radaxian. It is the eighth level of Alex Kidd in Miracle World.


Radaxian Castle is inhabited by the Radaxian royal family, including Alex Kidd, until he was kidnapped as a boy. Alex's twin brother, Igul, took control of the crown of Radaxian until the prince was overthrown and taken prisoner by Janken the Great. Alex infiltrated the castle to save his brother who was held prisoner there by Janken. The castle was where Alex finally defeated Gooseka the Slippery, third among Janken's minions.
