Energy, or Life Energy, refers to the life-force or durability of a being.
If Samus Aran ever runs out of energy, she will die, triggering a Game Over. To stay alive, she must regularly keep her energy levels charged by collecting Energy Capsules, as well as Energy Tanks to increase her capacity. Depending on the game, she can also fully replenish her energy by visiting Save Stations, Recharge Stations, Navigation Booths, or her Gunship. Her Energy Meter keeps track of her energy levels.
Metroids are able to draw pure energy from their prey. In Super Metroid and Metroid Prime 3: Corruption, Space Pirates, Federation Marines, and random wildlife can be found with their "life energy" drained, likely by Metroids. The brittle remains crumble to dust on contact. This gives an indication as to what happens to something with its energy drained. Oddly, in Super Metroid, even a Torizo is found drained of energy, despite being largely mechanical; a possible explanation for this is that the Torizo, like the Chozo Statues, are organic to some extent. However, it is demonstrated through Samus's Metroid powers in Metroid Dread that Metroids can also drain energy from seemingly non-organic machinery, as in the case of E.M.M.I.-07PB, Itorash, and Samus's Gunship.
