Merukimon

Merukimon is a God Man Digimon whose name and design are derived from Mercury, the Roman god of messengers and commerce. One of the Olympus Twelve, it is a Digimon god of genius who boasts of being the fastest in the Digital World. It is able to outstrip the fastest runner, becoming impossible to perceive with the naked eye, so it is said that all images of Merukimon in records and documents are just afterimages. It hates to stay in the same place, and as it is always wandering the Digital World, it is surely difficult to encounter. Merukimon excels in Shamanism, and its favorite knife "Aztec" is able to slice through space.
