Gypsy Danger is a third-generation Mark-3 Mecha originally based at the Alaskan Base of the United States, 79 meters tall, weighing 7,100 tons, nuclear-powered, with two pilots.
Before Storm Red and Eureka Raider entered service, Gypsy Danger used to be the Mecha with the highest kill count in the world,
and its pilots, the two brothers Yanxy Beckt and Raleigh Becket, were without a doubt human Heroes.
Until five years ago, when Anchorage, Alaska was attacked by deep-sea creatures, Gypsy was ordered to sortie and engaged in a fierce battle with a deep-sea Giant Beast called Sickle Head.
Although Sickle Head was eventually eliminated, one of Gypsy's pilots, Yanxy Beckt, unfortunately died in action,
and Gypsy herself was severely damaged and extremely difficult to repair.
Yanxy Beckt's death was something his brother Raleigh Becket could not accept,
