Warriors of Steel

The Spirits of Steel were created by AncientWisemon, the Ancient Warrior of Steel, as the legacy of his power. The Spirits of Steel have the ability to combine with each other or with Spirits of other elements, becoming even more powerful.

AncientWisemon
AncientWisemon is an Ancient Mineral Digimon and one of the ten Ancient Warriors with the power over steel. He has unsurpassed intelligence and has access to the Akashic Records, in which all is described, from the start of the world to the end. He sees through all things in nature. He created the Spirits of Steel.

 Attacks 
 * Laplace's Demon: Rewrites the past and future by accessing the Akashic Records.
 * Elder Sign: Temporarily borrows an elder god's power and use it as his own.
 * Metalic Alloy: Allows him to form metal out of thin air and manipulate it at will.

Mercurymon
Mercurymon is a Champion-class Hybrid Digimon. He is the Legendary Warrior of Steel, using the power of AncientWisemon. His Japanese name Mercuremon comes from "mercure", the French word for mercury or quicksilver. He is not to be confused with Merukimon (with the Japanese name of Mercurymon), a Mega level Digimon who is named after Mercurius, the Roman Messenger of the Gods.

He has the business of setting up strategy, thinking of many strategies simultaneously. His style is a fussy personality, precisely explaining methods of battle and other things.

Attacks
 * Dark Reflection : Uses his Irony Shield mirrors to absorb enemy projectile attacks and return the attack back at them.
 * Offset Reflector: Only used in the 13th episode of the Japanese version, similar to Generous Mirror, except Mercurymon absorbs the attack in one mirror and emits it from the other.
 * Mirror Offset: Uses his Irony Shield mirrors to create a beam of white and green energy to blast his enemies.

Sakkakumon
Sakkakumon is an Ultimate-class Hybrid Digimon. He is the Legendary Warrior of Steel, using the power of AncientWisemon. His name comes from "sakkaku", the Japanese word for wrong impression and illusion. His original Japanese name is Sephirotmon for what what he resembles: the Sephirot.. This name is sometimes used in the card game.

An important feature of Sakkakumon is that each of the ten spheres of his body holds an element of the Ten Legendary Warriors: Fire, Water, Light, Thunder, Wind, Ice, Darkness, Wood, Earth, and Steel. His central sphere bears the Crest of Light.

Digimon Frontier
Attacks
 * Rumble Blend #1-10: When attacked with an elemental attack, he rearranges his body to fire the attack right back at the opponent.
 * Rain of Steel: each of his spheres break apart and form a circle with the "information" sphere in the middle and giant metal spikes rain down from the glowing sphere.
 * Coat of Iron: Each of his spheres transforms in to large metallic orbs and pummels the enemy.
 * Metallic Reflector: Projects energy beams from the ten spheres at once.
 * In Digimon Frontier, Sakkakumon is able to absorb, copy, and use attacks of elemental nature. The weakness of this ability is that attacks of multiple elements—-or those of single elements which have been mixed with other elemental attacks--are unable to be absorbed.
