Missing Advanced Elements

What could the last two advanced chakra natures be?

Frost Release

This is an advanced nature transformation that combines wind and lightning chakra to create and manipulate the cold.

Frost chakra is able to lower the temperature of anything it interacts with to extreme degrees, whether that’s the air, the earth, non-living objects or living creatures.

It can affect inanimate objects such as making bladed weapons vulnerable by cooling them until they become fragile and brittle, able to break with the smallest amount of stress. It can affect the surrounding atmosphere to create a zone of incredible cold that humans would struggle to survive in as if caught in a winter storm, or even the earth such as turning a marshy swamp or a lava pit into hard, solid earth.

The most obvious example of its ability is to change the state of a liquid into a solid via cooling such as turning water into ice. This overlaps with the Ice Release kekkei genkai but there are key differences between them. Frost Release cannot manipulate ice and only creates it as a byproduct of lowering the temperature whereas Ice Release can manipulate it and only affects the temperature as a byproduct of generating said ice. Furthermore, frost chakra can be used to freeze practically any type of liquid rather than just water alone.

But frost chakra shows its qualities best when used directly against a living target. At its lower levels, it can simply make the target feel incredibly cold as if experiencing a severe chill that makes them shake and saps their strength. This can be taken further by freezing the body tissues to render them numb as they lose all sensation and struggle to use their muscles and joints as frostbite sets in. Or they can outright freeze a human being solid so that they become nothing more than a lifeless, frozen statue.

This could be called the antithesis of Scorch Release which, in contrast, raises the temperature to generate heat, making them a unique pair among the advanced elements as two chakra types that work on opposite ends of the same principle. But as advanced elements do not have inherent weaknesses, a clash between Frost Release and Scorch Release of equal strength would result in them cancelling each other out rather than one overcome the other as opposed to a clash between Water Release and Fire Release for example.

Unsurprisingly, the Frost Release kekkei genkai is known to exist in the Village Hidden in the Frost.

Thunder Release

This is an advanced nature transformation that combines fire and lightning chakra to create and manipulate vibrations.

Thunder chakra is capable of passing through mediums such as air, earth and water to reach the target. It can generate earthquake by sending intense vibrations underground to shake the earth, knocking over their enemies and potentially tearing open fissures. It can bring down entire buildings by breaking down the integrity of their foundations until they collapse on themselves. Even weapons can be shattered by shaking them to pieces with the vibrations, protecting the user from kunai and shuriken. And is particularly effective on human targets as its vibrations can unleash havoc on their internal organs like the Hyuuga Clan’s Gentle fist, albeit through different means.

The vibrations provide benefits even when applied to the user’s body such as causing them vibrate with such speed that their appearance appears blurred to eye, making it difficult to see their movements. And when applied to weapons via chakra flow, it can make bladed weapons much more effective at cutting and piercing like Lightning Release itself.

But the most common and most powerful use of thunder chakra is when its vibrations are shaped into shockwaves to attack their enemy. Its effect can merely push the target over, repel them away or even tear them apart depending on what is being struck and the scale and frequency of the shock wave itself.

The man who would become the First Raikage was known as Thunderous A for his Thunder Release. He was one of those lucky few who possessed a kekkei genkai through genetic mutation rather than inheritance and created the jutsu style himself to devastating effect.

A master of taijutsu and ninjutsu, A combined his thunder chakra with close quarters combat to devastate his enemy’s insides with each blow, smash his way through any kind of obstacle or defense and even accelerate his body to extreme speeds by riding his own shockwaves in a straight-forward, highly destructive charge. His most deadly attack – the one he was named for, in fact – was a combination of Lightning Release and Thunder Release which fired a powerful lightning bolt through the target and then followed with a thunderclap that levelled anything that remained standing.
