Mercurymon (Frontier)

Mercurymon (Japanese: Mecuremon) is a mutant Digimon from the Digimon Frontier series, appearing as one of the villains. He is the Legendary Warrior of Metal, using the power of AncientWisemon. 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 and using it himself to become ShadowSeraphimon. As Sakkakumon, the ten spheres that form his body each hold a dimension with elemental attributes of the 10 Warriors.

Sakkakumon (Japanese: Sephirotmon) is the Slide-evolved version of Mercurymon. He is the Beast Spirt of Steel; one of the most powerful and the largest of the beast spirits. It took a combined attack by Aldamon, Kazemon, Beetlemon, and Kumamon to defeat him. An important feature of Sakkakumon 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.

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.

Mercurymon/Sakkakumon was voiced by Yasunori Matsumoto (Japan) and Daran Norris (US)

Sakkakumon

 * Rumble Blend #1-10: When attacked with an elemental attack, he rearranges his body to fire the attack right back at the opponent.

Important events
When the Legendary Warriors were within 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.
