Mercurymon (Frontier)

One of the villains of the anime, Digimon Frontier. Mercurymon is the Legendary Warrior of Metal, using the power of AncientWisemon A mutant Digimon, Mercurymon is a crafty strategist, thinking of many strategies simultaneously. He has a fussy personality when it comes to precisely explaining methods of battle and such. He attacks his enemy's weak points but his behavior outside of calculations is brittle. One of his accomplishments was stealing Seraphimon's Fractal Code & using it himself to become ShadowSeraphimon. As Sakkuakmon, the ten spheres that form his body each hold a dimension with elemental attributes of the 10 Warriors.

He was finally defeated by the DigiDestined while in his Sakkakumon form and both of his spirits were transferred to Takuya's D-Tector. Mercurymon's spirits were later transferred into Koji's D-Tector so he could Hyper Spirit Evolve to MagnaGarurumon.

Attacks
Mercurymon
 * Generous Mirror (Dark Relfection): Uses his Irony Shield mirrors to absorb enemy projectile attacks & return the attack back at them.
 * Mirror Offset: Uses his Irony Shield mirrors to create a beam of white & green energy to blast his enemies.

Sakkakumon
Sakkakumon is the Beast Spirt of Steel and one of the most powerfull and the largest of the beast spirits. It took a combined attack Aldamon, Kazamon, Beetlemon, and Kumamon to defeat him. One of the things that make Sakkakumon special is that each of the 10 Spheres of his body holds an element of the 10 Legendary Warriors, Fire, Water, Light, Thunder, Wind, Ice, Darkness, Wood, Earth, and Steel. These spheres are arranged in the shape of the Sephiroth, hence his Japanese name, Sephirothmon.
 * Rumble Blend #1-10: When attacked with a elemental attack, he rearranges his body to fire the attack right back at the opponent.

Important Fact
When the Legendary Warriors were in Sakkakumon, he had different Digimon that represented each element in each Sphere. He had Volcamon for the Earth Sphere, Karatenmon for the Wind Sphere, Asuramon for the Fire Sphere, Parrotmon in the Thunder Sphere, Cherrymon in the Wood Sphere, and IceLeomon in the Ice Sphere. These six Digimon seemed like Digimon that had lost their Fractal Code to Mercurymon as their dissolved much differently from the others. Ranamon seemed to bring herself and her Honeybeemon groupies into the Water Sphere while Duskmon entered the Darkness Sphere. Mercurymon's sub-conscience was in the Steel Sphere (which is Sakkakumon's head) and Seraphimon's data was in the Light Sphere.
