The Energy Meter, also known as Energy Display is a crucial feature of the Heads-Up Display in all Metroid games, serving as the series' health bar. Located in the top left of the screen in 2-D games and Metroid: Other M, and at the top of the Visors in the Prime series, it displays the number of energy units that Samus has, while also displaying her Energy Tanks above or below this number.
The meter is represented by two digit numbers and the word "Energy" (although in the original Metroid, "EN" is displayed, and Metroid: Zero Mission only displays the numbers). The meter records up to 99 units per Tank. The Prime games and Other M feature an energy bar along with the number digits, which gradually shrinks and refills as Samus loses and regains energy. If her energy is drained completely, Samus will die or the Power Suit will be unable to protect her, leading to the Game Over screen. In 3-D games, if energy drops to a low level, the HUD will beep and flash a warning to Samus. To stay alive, Samus must keep the shielding of her Power Suit charged by obtaining Energy Capsules, using Energy Charge or Recharge Stations (or certain Save Stations), or entering her Gunship.
Near the end of Metroid Prime 3: Corruption, the Energy Meter is changed into a Phazon level, representing Samus' level of Phazon corruption. To avoid dying of Terminal Corruption, Samus is required to drain her energy into objects or by collecting Anti-Phazon Units.
In Metroid Prime: Federation Force, the Federation Marines have Energy Meters as well, albeit on the left side of the HUD. Their Mech suits are not known to be able to expand the amount of energy they can have.
Boss health bar[edit | edit source]
Certain bosses in 3-D games have energy meters as well. These usually rest underneath Samus's meter on the HUD and feature the boss' name. Samus's goal during boss fights is quite obviously to kill, defeat or destroy the creature or mechanism she is engaging by attacking it until its energy is depleted. Some bosses can replenish their health through various means or shield themselves from attack, forcing Samus to change her strategy or wait out the shielding period. The Dark Visor places the bar at the bottom of the Visor, and also increases the font of the boss' name. Metroid Prime Hunters colors the bar red when the enemy's health is critical.
The Spire Structure in Corruption has a health bar, which is drained as Space Pirate Assault Skiffs fire at it. Samus must ensure that the Spire is not destroyed before it reaches the point over the Elysia Seed, where it will drop the Theronian Bomb on the Leviathan Shield protecting the Seed.
In Other M, boss health bars must be "scanned" by locking onto them for a few seconds, which will gradually add the bar to the HUD in Search View. Letting go of the lock before the bar is filled will cancel the action.
