Health Meter

In the Mario series, the Health Meter is an on-screen indicator of how much health Mario (or another character) currently has left. It usually appears somewhere on the top of the screen, but can also appear in other locations on the screen as well.

Super Mario Bros. 2
In Super Mario Bros. 2, the Health Meter appears in the top-left corner of the screen at the start of each level, and consists of two hexagons arranged vertically. These hexagons were later changed to hearts in the Super Mario All-Stars remake of the original game as well as in Super Mario Advance. Each section of the Health Meter represents one hit point each. Normally, the hexagons or hearts will be colored red. When the player is attacked by enemies however, one health section will be lost, and will turn white instead of red (in the remake, it will turn blue). The character will shrink when only one health section remains.

Sections of the Health Meter can be replenished by collecting hearts. These hearts can often be found floating upward from the ground after a number of enemies have been defeated. In each level, there are two Mushrooms hidden in Subspace which will each increase the sections of the Health Meter by one, up to a maximum of four. It will then revert back to just two health sections at the beginning of the next level.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64, Mario’s Health Meter is normally not displayed on the screen until he takes considerable damage from falling or touching enemies, etc. When it does appear, it is displayed on the top middle of the screen. In this game, it is shaped like Mario’s head, with a circle in the middle which displays 8 health sections. When he takes damage, some of the sections will gradually disappear.

The color of the health sections corresponds to the number of health sections that remain after he has taken damage: eight to seven are blue, six to five are green, four to three are yellow, and two to one are red. Mario can refill his Health Meter by collecting various coins: Yellow Coins will replenish one section, Red Coins will replenish two sections, and Blue Coins will replenish five sections. He can also refill it by running through Spinning Hearts, which can be found in most if not all of the levels. The faster he runs through them, the more health he will regain.

When the Health Meter reaches two sections, Mario will begin to pant when standing still, though he can still perform moves. If the Health Meter runs out at any time, Mario will lose a life and forcibly exit whatever level he is currently in (excluding Peach’s Castle). When he no longer has any lives left, he will be given a Game Over.

In this game, Mario's Health Meter also acts as his breath meter when he dives underwater. After diving underwater, the health sections will gradually deplete. When only two sections remain, an alarm will begin to go off; if Mario does not surface before the two sections have completely run out, he will lose a life. On the flip side, if Mario remains in the water with his head above the water, the Health Meter will completely refill (excluding the water in Snowman's Land, which actually depletes his health rather than replenishing it, regardless of whether or not his head is above water). It will also automatically refill immediately after Mario exits a level after collecting a Power Star if it’s not already filled.

The Health Meter appeared again in the remake, Super Mario 64 DS, where it was exactly the same.

Super Mario Sunshine
In Super Mario Sunshine, Mario's Health Meter is appropriately shaped like a sun. Again, it will not visibly appear onscreen until Mario takes enough damage. When it appears, it will be positioned in the top right corner of the screen. There are once again eight sections of health, which comprise the rays of the sun. The inside of the "sun meter" is a spiral shape, though this cannot be filled up.

It is normally a golden-orange color when completely filled, and each individual section will "flash" when completely filled. When Mario takes damage, the rays of the sun will gradually become blacked out to signify the loss of energy. When they have been blacked out, they will no longer flash. He can regain energy by collecting normal Coins, which will refill one section, or Red Coins, which will refill two sections (Blue Coins will no longer work in this game as they are traded for Shine Sprites instead).

When the Health Meter has lost five sections of energy, an alarm will start to sound for the remaining three sections of health. As each section after this is gradually lost, the alarm will sound faster, and the energy sections will flash to match its warning. As it gets gradually lower, Mario will start to droop lower and lower, visibly getting weaker from the lack of energy. When it has been completely depleted, Mario will lose a life, or if he has no more to lose, will receive a Game Over. It will automatically be fully depleted if Mario falls in lava, fails a timed Red Coin challenge, or loses a race to Il Piantissimo.

Unlike Super Mario 64, there is a separate meter for Mario's air meter when he is underwater, the only difference being that the entire meter is blue and that the health sections will continually deplete underwater. When the meter depletes to three sections, an alarm will sound as it gets steadily lower, and will continue to do so until Mario collects a coin or returns to the surface.

Super Mario Galaxy
In Super Mario Galaxy, the Health Meter appears in the top right hand corner of the screen after Mario has taken considerable damage, or after Mario has remained inactive for a certain period of time. It is shaped like a circle (or arguably, a planet) and has a total of only three health wedges as opposed to the eight in the previous two games. Thus, Mario can lose a life in only three hits if he is not careful. If he has no lives left, he will get a Game Over.

One of the new features of this game involves the inclusion of a new item called the Life Mushroom, which will increase Mario’s Health Meter from three to six when it is collected. However, if at any time the health sections drop back below four, the Health Meter will revert back to three, until another Life Mushroom is collected.

The coloration of the regular Health Meter in this game is as follows: three wedges is light blue, two wedges is yellow, and one wedge is red. The additional three sections that are added as a result of the Life Mushroom are all colored green, and do not change color unless the Health Meter drops below four.

As neither Red Coins nor Blue Coins appear in this game, they cannot be used to refill Mario’s Health Meter when it gets low. Instead, he must seek out regular Coins, which can be collected after defeating most enemies and will refill one section of his Health Meter. Purple Coins make their first appearance in this game, but they do not affect the Health Meter in any way.

When the Health Meter drops below two (and there is only one section left), a warning alarm will begin to sound. This will continue until Mario is able to pick up at least one coin, which will fill it up again. Also, the Health Meter is different from Mario’s air meter when he swims underwater. The meter that does appear when he is underwater is similar to the meter that appears when Mario is flying as Bee Mario. Mario will only start taking damage underwater when his air gauge has been fully depleted, at which point his Health Meter will be quickly depleted as well.

Note that Mario's Health Meter will automatically be decreased to just one health wedge at the beginning of every Daredevil Comet level (the only difference being that no alarm will sound under these conditions). Mario will then have to complete the level without taking damage even once.

In this game, a number of different factors can cause Mario's Health Meter to be depleted immediately, including falling into a Black Hole, being crushed by a Thwomp or Tox Box, falling into sand or Poison Water, touching Dark Matter, or failing a timed Purple Comet, Speedy Comet, or Cosmic Comet challenge.

Super Mario Galaxy 2
The Health Meter in Super Mario Galaxy 2 looks and behaves in the same way as it did in its predecessor. One minor difference includes the fact that if the player collects another Life Mushroom while one is still in effect, he/she will receive a 1-Up. However, this will only work if all six sections of the Health Meter are filled when Mario collects the second Life Mushroom. If they are not, then the second Life Mushroom will only refill the Health Meter back to six, instead of giving Mario a 1-Up. This feature was not included in the previous game.

In this game, Mario's Health Meter will be depleted immediately if he falls into a Black Hole, is crushed by a Thwomp, Whomp, Rhomp, or Tox Box, falls into sand, touches Dark Matter, or fails a timed Purple Comet, Speedy Comet, or Romp Comet challenge.

Yoshi's Story
In Yoshi's Story, the Health Meter (or Smile Meter, as it is also called in this game) is depicted as a smiling flower which appears in the upper left-hand corner of the screen during gameplay. Normally, the Health Meter will have a total of eight sections, signified by the eight white petals positioned around the circular center of the smiling flower. In addition to displaying the health of the Baby Yoshis, the Health Meter in this game also represents the current mood of the Baby Yoshis.

When a Baby Yoshi takes damage from touching enemies or other hazards, the petals will begin to gradually fall away from the center of the flower, starting with the topmost left petal and going counterclockwise. In addition, the face of the flower will slowly change from a smile to a frown. When this happens, the color of the face on the flower will also change. The face will start out being orange, and will turn yellow as health is lost, eventually turning blue when no flower petals remain at all.

A Baby Yoshi can only take damage up to eight times before the flower will start frowning (as there are only eight petals on the flower). If the Baby Yoshi is hit one additional time while the flower's face is frowning, the dinosaur will faint and be captured by Baby Bowser's Toadies. The player can regain health by having a Baby Yoshi eat various fruit. When the Baby Yoshi eats fruit, any lost petals will return to the flower and it will begin smiling once again.

Yoshi's Universal Gravitation
In Yoshi's Universal Gravitation, the Health Meter appears in the top-left corner of the screen as a smiling orange sun with eight white triangle shaped rays around it. Each of these triangle rays represent one section of health, for a total of eight sections. This variation of the Health Meter is very similar to the one from Yoshi's Story in both shape and color.

When Yoshi touches an enemy or other obstacle, health is lost, signified by some of the white triangle rays falling away from the sun in a counterclockwise direction. As more and more health sections fall away, the loss of energy will begin to be reflected by the sun's expression. It will start out being orange with sunglasses and a large smile. When some rays have been lost, its color will fade to a gold-yellow, it will lose its sunglasses, and its smile will diminish slightly.

If Yoshi sustains more damage, the expression of the sun will remain the same, though more of the sun's rays will be lost. When no more of the sun's rays remain, the face of the sun will turn blue and begin frowning. If Yoshi sustains any more damage after this, he will lose a life.

Mario Sports Mix
The Health Meter in Mario Sports Mix is used only in dodgeball matches, as well as the dodgeball minigame Bob-omb Dodge. It is shaped like a circle with a black line going down the top half of its middle and ending at the circle's center. Depending on the character that the player is currently using, the icon shown in the top corner or the Health Meter will change accordingly. The player should note that in this game, the Health Meter will appear along the top of the screen for every character that is playing. This Health Meter also appeared in the game's final battle against Behemoth.

When the player's character is hit by a dodgeball or another item, such as a Bob-omb, some health will be lost. The amount of health lost will depend on the item the character is hit with, as certain items will cause more or less damage than others. In any case, when a character is hit with an item, the chunk of health that is lost will flash red briefly before disappearing completely, leaving a black space in its place. If a character is hit by a special attack, a large amount of health will be lost. If the Health Meter for a certain character is depleted completely, that character will be out for the remainder of the match.

Also the Health Meter appears in the final battle with Behemoth.

Super Smash Bros. series
In the Super Smash Bros. series, the Health Meter always appears on the bottom of the screen. It acts as a damage counter which displays the amount of damage that a particular character has taken as a percentage. The higher the percentage goes, the more damage the character has taken. As the character takes more damage, the color of the percentage will gradually change from white to a dark red, and the character will simultaneously become easier for the opponents to KO them. The highest amount of damage a character can possibly take is 999%. Food, Heart Containers and Maxim Tomatoes can help reduce the amount of damage that a character has taken. In all games, the Health Meter appears for each character that participates in a match.

Aside from displaying the damage of a character, the Health Meter will also display other information. For example, the name of the character will always be displayed directly under the damage percentage, and an icon of the character's face will be displayed to the left of the damage percentage (in Super Smash Bros. Brawl only). The symbol signifying the series that the character comes from will appear behind the damage percentage. In Stock matches, up to five circles (represented as heads in the first two Super Smash Bros. games) will appear above the damage percentage representing the amount of Stock that the character currently has left. One of the circles will disappear for every time that the character is flung off the screen. When the character has no circles left, they will be defeated. In Time matches, the number of KOs is shown above the damage percentage. A point is earned or lost if the character KOs an opponent or gets KO'd, respectively.

Trivia

 * Normally, Mario will always lose a life when his Health Meter reaches zero. However, in some cases, if he touches a Coin before hitting the ground after being hit by an enemy, for instance, his Health Meter will be refilled back to one, and he will not lose a life. An example of this is the Coin Revival glitch in Super Mario Galaxy.
 * The beta version of the Health Meter from Super Mario Sunshine looked slightly different from the one that appears in the final version of the game, though it still resembled a sun.
 * Similarly, the Health Meter in the beta version of Super Mario Galaxy originally had a total of eight sections, like in the first two Super Mario games. It featured the same coloration as in Super Mario 64, although later the green and blue colors were switched.
 * The Health Meter in the beta version of Mario Sports Mix looked very similar to the Health Meter from Super Mario Galaxy and Super Mario Galaxy 2, except for the fact that it had four sections instead of just three.
