In his fight against his master, Gold Saint Aquarius Camus, Hyoga awoke the 7th sense and used absolute zero air, being able even to freeze the Gold Clothes, surpassing his teacher. In the Hades Arc, Hyoga was able to use a variation of the Freezing Coffin of his teacher but it was not named.
Diamond Dust: Basic technique of freezing, it is the basis of Hyoga's blows. Hyoga fire with a punch a burst of ice crystals attacking the enemy from the front, freezing and / or paralyzing it. With the evolution of the Hyoga's cosmos, the blow of containment was enough to defeat various enemies. It is generally the technique that uses Hyoga first, to test the strength of the opponent. The blow may sufer variations, as used to reflect the psychic blow of Phoenix Ikki.

The Aurora Thunder Attack is a horizontal variation of the Kholodinyi Smerch. The "Aurora Thunder Attack" clasps both of Hyoga's hands together as he expels snow and ice at the opponent.
Hyoga learns Aurora Execution directly from battling his master, Gold Saint Aquarius Camus.

The Cygnus Cloth is one of the Bronze Cloths. The Cygnus Cloth represents the Cygnus Constellation, which is associated to various swans from Greek mythology, included Zeus, disguised as a swan to seduce Leda, and Orpheus, that was transformed into a swan after his murder. The Cygnus Constellation is also known as the Northern Cross, and it's the reason why Kurumada made Hyoga always carry a cross and rosary with him. While it is not as durable as the shield found on the Dragon Cloth, nor does it contain regenerative abilities like the Phoenix Cloth, the Cygnus Cloth is nevertheless revered as a premiere Bronze Cloth. Being that it had been encased in a frozen iceberg years prior, it naturally absorbed the Arctic properties of its surroundings. Thus, it is quite the feat for one to completely shatter it. Phoenix Ikki comments that it also had a "frost armor" effect, when he fought Hyoga and smashed a hole on Hyoga's chest guard, he felt his right wrist freeze. The Bronze Cloth of Cygnus constantly evolves to expand its durability and power.
