DigiXros Unit

The term "DigiXros Unit" refers to the various Digimon that serve as components of a DigiXros. Unlike DNA Digivolution, the DigiXros that results from a combination of Digimon depends only on its most basic DigiXros Units and not the immediate components. For example, the Shoutmon X4 DigiXros uses Shoutmon, Ballistamon, Dorulumon, and the Starmons as its basic DigiXros units; however, Shoutmon and Ballistamon can be replaced by Shoutmon X2, or Shoutmon and the Starmons by Shoutmon + Star Sword. When the same DigiXros Units produce a different DigiXros, for instance the five combinations of SkullKnightmon and DeadlyAxemon, or Shoutmon Star Wheel, these variations are due to the will of the Digimon, and not any differences in their immediate components.

The Digimon Xros Wars anime and manga generally use any combination of the "canon" DigiXros units to form the needed DigiXros. However, the Super Digica Taisen card and arcade game has a limit of three DigiXros Units, while for the Digimon Xros Loader toy, the limits depend on the Leader Digimon, with a max limit of five units. These limits restrict the combinations that can be used in the game; notably, both games have to approximate the DigiXros combination for Shoutmon X7, whose "correct" DigiXros Units are Shoutmon DX, Ballistamon, Dorulumon, the Starmons, and Sparrowmon. Super Digica Taisen uses Shoutmon DX Ｘ Shoutmon X5, Shoutmon DX Ｘ Shoutmon X4 Ｘ Sparrowmon, and OmegaShoutmon Ｘ ZekeGreymon Ｘ Shoutmon X5, while the Digimon Xros Loader uses OmegaShoutmon Ｘ Ballistamon Ｘ Dorulumon Ｘ Starmons Ｘ Sparrowmon.

Each act of Super Digica Taisen adds new DigiXroses that can be used in both the card and arcade game. The Data Carddas site lists all of the new DigiXros combinations for each act.
