Avengers End Game is a sudden and powerful evil force that poses a fatal threat to the earth. No superhero can resist it alone. The s.h.i.e.l.i.e.l.l.d., which has long been committed to protecting global security, was taken by surprise. Its commander Nick Frey, the one eyed man, realized that he must create a "strongest alliance in history" and gather superheroes from all sides to fight together in order to save the world from suffering and resist the invasion of the dark forces. Therefore, the "Avenger alliance" composed of six superheroes - "Iron Man", "Thor", "Captain America", "Hulk", "black widow" and "eagle eye" came into being. They showed their magic powers and united as one, and finally defeated the evil forces and ensured the safety of the earth.
