Lava Adds Awesome

""We need... lava, of course, more lava and... deadly traps! Oh yeah!" (adds "even more lava" to the diagram)"

- Bowser, Bowser's Evil Plan

Figuratively speaking.

One way to make an artifact, weapon, or situation even better is to get lava involved somehow. After all, if something is already pretty awesome on its own, that said something would be really freakin' awesome if it happens to be using burning magma in the process. It doesn't matter if the lava is even relevant; just the inclusion of a flowing fiery-orange flow is enough to invoke the sense of raw power -- strong enough to melt MOUNTAINS! -- barely held in check.

Broadly speaking, this trope covers instances where lava or magma is added to something just to make it better.

A Super-Trope to:
 * Climactic Volcano Backdrop (a lava backdrop)
 * The Lava Caves of New York (secret underground lava caverns)
 * Lava Pit (pits of lava dot the landscape)
 * Lethal Lava Land (entire worlds made of lava)
 * Magma Man (a character made of lava)

Often invokes Convection, Schmonvection. Also see Awesomeness Is Volatile and Incendiary Exponent.

And to be clear: Magma refers to the material while it's still underground and not yet erupted from a volcano. Lava is the stuff when it's above ground.

Anime and Manga
outta her sleeve. -->
 * In Mahou Sensei Negima, the ultimate spell of Earth element wouldn't be awesome enough without it.
 * Mazinger Z: Mazinger-Z's Home Base was located on the foot of Mount Fuji. Such a perfect setup was used for animating many battles and squirmishes would have been less cool without the Climactic Volcano Backdrop, the characters brawling around a Lava Pit or soaring above Mount Fuji's crater. In one episode, Dr. Hell attempted to set an eruption off to bury the Photon Research Institute beneath tons of lava. In another episode, Mazinger-Z was tossed into a volcano. In the Gosaku Ota manga episodes, The Dragon Baron Ashura's master plan involved to set volcanic eruptions off throughout Japan...
 * Great Mazinger: One of the weapons of Marquis Janus' Island Base was an artificial volcano built on the island could vomit rocks and lava when Janus needed.
 * Naruto's Mizukage Mei can use Lava as a combination of fire and earth, in addition to her water, fire, earth and acid skills. She pulls this outta her sleeve.

 * The final showdown of Revenge of the Sith has Anakin and Obi-Wan duking it out on the lava planet of Mustafar.

Literature
"Luke walked across the lake of fire.
 * Many depictions of Fire and Brimstone Hell, especially visual works, will have bubbling pools and flowing streams of lava as background elements.
 * Luke Skywalker spontaneously develops the ability to walk on lava in the first book of the Jedi Academy Trilogy.

He did not think about it. The lava refused to touch his feet. Only The Force burned bright around him. One step after another, he strode across the flaming rock, letting himself see nothing but his goal until he stood again on solid ground on the far side of the lake of fire, with Gantoris and his people."

Video Games

 * Not only does Super Mario Galaxy feature Melty Molten Galaxy, a planet made of lava, but it's caught between two other planets also made of lava -- a lava solar system.

 * One of the weapons in Ratchet and Clank is the Lava Gun, a modified flamethrower that shoots a continuous stream of lava.

 * Dark Souls has two Lethal Lava Land levels. There are also the Chaos Pyromancies, the most powerful fire spells, which leave pools of lava on the floor when used.

 * Metroid Prime: Hunters features the Magmaul, which is basically a magma grenade launcher.
 * The underground realm of the Deep Roads in Dragon Age has a lot of lava, to the point that the dwarves have lava fountains and lava waterfalls as decorations in the same way surfacers might use water.
 * Minecraft allows you to collect and use lava in constructions. If you can avoid being burned by it, of course. Lava also happens to be the longest-lasting heat source for furnaces; unfortunately, using a lava bucket in a furnace will destroy the bucket, and depending on the map you may have to construct a portal to the Nether just to have a steady source of lava.
 * Of course, there you run into the problem that getting the obsidian to create the portal is best done with lava... GAH!
 * Any fire-base dungeon in The Legend of Zelda series, especially volcano levels in the Death Mountains. Usually, you also have to fight burning bats and huge monsters that set themselves on fire.
