Every chakra nature, kekkei genkai and hidden release. Each one opens its own skill tree once awakened, usually with its DNA.

Kekkei genkais

Wind and water frozen into mirrors, needles, and walls of ice.

Earth and water combined into living wood that grows on command.

Fire and earth melted together into molten rock.

Wind and earth that pull iron and gold sand to the user's will.

Lightning and water woven into beams of living current.

Fire and wind together: heat that dries anything it touches to a husk.

Earth charged with lightning, moulded into things that detonate.

Black flames shaped at will. Only a Sharingan can command them.

Wind and lightning together: speed beyond what the eye can follow.

Earth forged in fire: a body as hard as steel.

A hidden nature that devours chakra. Its true composition is unknown; this one is a placeholder.

Wind and water whipped into a raging storm.

Crystallises everything around it, even the moisture in the air.

Earth softened by water into mud that swallows and binds.

Konan's art: the body come apart into sheets of paper, folded into wings, blades, and copies packed with explosive tags.

Sai's Super Beast Imitating Drawing: beasts painted in ink on a scroll that leap off it alive, and ink that clouds the air.

Beast-like taijutsu fought side by side with a ninja hound: spinning fangs and the man-beast transformations.

Shadow Release: the user's shadow, stretched and shaped, binding those it touches.

Shikotsumyaku: the dances of bone. Armour grown out through the skin, a sword drawn from the palm, a drill over the arm, and a forest of bone spikes.
Kekkei totas
Hidden clan releases

The Uzumaki's chakra made solid: golden adamantine chains that bind anything, even a tailed beast.

Healing, and the precise chakra control it demands.
