Dragon Knight is a humanoid monster, which makes up the humanoid foot soldiers of XANA.
Dark Dragon KnightEdit
This version of Dragon Knights are a group of regular Dark Knights that was enhanced by Shadow, prior to his departure from XANA's cabal-like legion. These ones were given the ability of independent thoughts, along with their own set(s) of Shadow's power of darkness, which can allow them to evolve other programs by fusing with them through possession.
Blood Dragon KnightEdit
These are much stronger versions of the Dragon Knights, that were introduced during the time the Lyoko Warriors first made it to the Carbon Copy.
