The Magic Crystal (Chinese: 魔翡翠; released in the Philippines as Fight to Win) is a 1986 Hong Kong action film written and directed by Wong Jing.

Due to time constraints, Sergeant Shek of the Special Duty Unit recruits mercenary Andy Lo, known as the "Eagle Hunter", to retrieve it.

Afterward, Cindy and her partner reveal to Andy that they know of his identity as the Eagle Hunter and inform him of Shum's situation of being hunted by the KGB and persuades him to cooperate with them to help his friend.

Afterwards, Shum leaves a baggage containing the mysterious artifact in Andy's hotel room before being captured by Karov, head of the KGB.

When Sergeant Shek comes, he questions Andy, Winnie, and Lo Sai about their attack the previous evening, with the latter trying to hide the awkward limb swap.

Andy fights off Karov's thug and escape with Winnie and tells Snooker to take a look at their baggage brought back from Greece.

Karov escapes after Andy engages in a fight with him but they were able to rescue Ban-ban and Cindy suggests to keep the child protected at the police station.

Andy, Cindy, Snooker fall into an underground level full of booby traps while Billy chases Karov, and the trio find a device with the recording Venus detailing his journey to Earth and the jade, which is his technological pet, will help him return to his home planet.
