One side effect of the X-Antibody is its ability to cause special evolutions in Digimon. When the levels of X-Antibody present in a Digimon's body reach a second threshold, they extract latent data from the Digimon's Digicore and use that to evolve the Digimon into a new form that expresses that latent data.
This is the lowest power class of X-Forms available to players of DMW.
