Lava is a hazard that appears in many Mario games. It mainly serves as a hazard where if Mario touches one, he instantly dies though this effect is different in games like Super Mario 64 and Super Mario Sunshine. Lava is usually home to Podoboos and is Bowser's main hazard he has in his castles. Even a Starman cannot protect Mario from this deadly obstacle. The effect lava has on Bowser varies ranging from not affecting him to actually killing him at least once. This could mean that there are different temperatures (or even separate types) of lava that differ from game to game.
Lava appears as a hazard in Super Mario Bros., Lava mainly appears in Castle levels where if Mario falls into it, he instantly dies. In Super Mario Bros, this is a classic way of finishing off Bowser at the end of levels. Podoboos also tend to jump out of the lava serving as an obstacle to avoid when crossing the lava.
Lava appears again in Super Mario Bros.: The Lost Levels once again serving the same role as the previous game and once again being found in the game's Castles however this time, there are some lava pit gaps that are much larger, additionally, the Podoboos may now do double or even triple jumps.
Lava appears again in Super Mario Bros. 3 being a common obstacle in the Fortresses, just as before, Podoboos are seen hopping out of the lava, lava can also be found on the ceilings of each level. Just as before, touching either type of lava will instantly kill Mario.
Lava appears on many levels in this game where it's purpose is the same as in the Super Mario Bros. games. Lava is commonly found in Castles and Fortress however for the first time, it is also found in caverns that go very deep underground. Some levels in Choco Island also have brown lava which has the same effect as regular lava. The first castle in this game is known for using lava to defeat Iggy Koopa. If Mario lands in lava, even if he has a Cape, he instantly dies. In addition to Podoboos, enemies known as Blarggs tend to lurk around in the lava. Larry Koopa's boss fight also has lava, in which Larry Koopa needs to be thrown into for Mario to defeat him. If Yoshi is to fall in lava, he will slowly sink rather than instantly dying. If Mario falls in the lava while on Yoshi, both will instantly die.
In Super Mario 64 and Super Mario 64 DS, Lava appears mainly on Lethal Lava Land and in Bowser in the Fire Sea in these games. If a character falls in the lava, they will lose three out of eight health points however if said character is capless, they lose four points of health. Lava is also used to defeat Bullies. On lava bridges, Podoboos tend to hop out of the lava bouncing along the bridge before dunking back into the lava on the other side. In some cases, Flamethrowers are also submerged beneath the lava shooting their flame jets periodically. If a Shell is used, one can surf over the lava without being scorched. If Mario touches lava as Metal Mario, he will still bounce in the air as if he touched it normally but won't take any damage. In the remake, this has been changed, if Metal Wario is to fall into lava, he will start slowly sinking into it (similar to the quicksand in the pyramid of Shifting Sand Land) and if he doesn't jump back out in time, he will be submerged and die.
In the game's beta files, codes for a Blue Lava are also shown to exist. Said blue lava was never used in-game, the blue lava would've come paired with Blue Podoboos.
In Super Mario Sunshine lava is seen in Corona Mountain as the primary obstacle to avoid. One touch of the lava will instantly kill Mario forcing him to restart the area from the beginning. Mario has to make use of F.L.U.D.D and the boat to avoid stumbling into the lava, more often than not, there will also be Blue Coins dangling over the lava forcing Mario to work out a strategy to obtain them. A type of Pollution similar to lava called Fiery Goop is found in Pianta Village which takes one health point off Mario upon contact thus burning him. It can be dozed away with either F.L.U.D.D or accurate splashes from the lake water.
Lava appears in Super Princess Peach, in this game, it can be seen in Fury Volcano and Bowser's Villa. If Peach touches lava, she will briefly catch fire, be launched into the air, and lose one hit point. If Peach falls back in the lava while her invincibility frames are still up, she will briefly default to Bowlbrella as if she landed in water until the frames wear off or until she hops back out quickly. If any enemies fall into the lava, they instantly die, lava can also come in wall forms as well which does damage as normal lava. Podoboos commonly make high leaps out of the lava and Peach must avoid them as they do. The grounds in the caves of Fury Volcano also contain busted earth which causes Lava Plumes to periodically erupt from the cracks. Bowser's Villa also contains rooms with blue lava (which is blocked off by a platform so Peach cannot fall in) which the heat-seeking Blue Podoboos hop out of in unlimited supplies.
Lava returns in New Super Mario Bros. as a common hazard in the Castles, the lava appears along the floor of the Castles and one touch of the lava will instantly kill Mario (or Luigi), not even the effects of a Starman or Mega Mushroom can protect Mario/Luigi from the lava, just as before, Podoboos are commonly seen hopping out of lava. Outside Castles, lava is also seen in levels found in the second half of World 8 in Bowser's territory and on the world map of said world. Lava is also seen in the Bowser Jr. boss fights of World 6-Fortress 2 and World 8-Fortress 2, in World 4-Fortress and World 8-6, the lava rises from the ground forcing Mario (or Luigi) to climb up the platforms to escape the rising lava, the lava continues rising until it has scorched Mario/Luigi or he has escaped. Most importantly, lava is seen in Bowser's first boss fight and after his defeat, he falls into the lava bath perishing and becoming Dry Bowser, lava is also seen in the boss fight with Mega Goomba but this lava is purely for aesthetic effect and has no impact on the boss.
In the game's beta files there is a different type of lava which resembles the lava seen in Super Mario Bros. which went unused, this lava functions similarly to regular lava but doesn't take up the level and can be placed as a small pool.
Lava is seen several galaxies of Super Mario Galaxy which include the Good Egg Galaxy (Octo-Magma Planet only), the Freezeflame Galaxy, the Toy Time Galaxy, Bowser Jr.'s Lava Reactor, the Melty Molten Galaxy, and Bowser's Galaxy Reactor. When Mario touches lava, it can scorch him terribly causing him to bounce in the air running around briefly thus losing a health point. The boss King Kaliente is a lava-dwelling Octopus who can spit fireballs and coconuts at Mario whist also launching Lava Bouncers at him. Lava Plumes can also erupt from the lava as an additional obstacle for Mario to avoid. The Star Ball is shown to be able to safely roll across lava, additionally, the use of the Ice Flower will turn Mario into Ice Mario allowing him to safely walk across lava (whilst also creating a trail of ice platforms). The various Sun Planets found in the Freezeflame Galaxy and Bowser's Galaxy Reactor also appear to be made of lava.

As shown, lava is much more common in this game than in the previous and also takes different roles in each of the Galaxies the substance is found in, in the Freezy Flake Galaxy, it is shown that Snowballs can be rolled in lava thus creating temporary snowy paths for crossing however the longer a snowball spends on the lava, it slowly melts before completely dissipating. In the Chompworks Galaxy, it is shown that Golden Chomps are actually made from lava, in the Shiverburn Galaxy, descending ice crystals that make contact with lava will form into temporary ice platforms (similar to the ones that Ice Mario makes in the previous game only much larger), the Melty Monster Galaxy has planets composed entirely of lava as well as an underground volcano with lava waves, lava rivers, and lava falls, Bowser's Galaxy Generator also has lava walls which can burn one as well, and the Boss Blitz Galaxy where a pool of lava serves as King Kaliente's lair once again.
