The First Bomb Component is the first acquirable part of the Theronian bomb, though it is the last to actually be seen. It is the only bomb component that can be accessed without the use of Seeker Missiles. After the lord's death, four Spinners circling the component activate. Samus' use of them lifts locks on the floor, and activates a control terminal in the room. Samus interfaces with it, and the floor releases the bomb, allowing her to call her gunship to pick up the component.
