Mercenary Digimon may have forms beyond their Mega stage known as Side Mega or Burst Mode. In general, Side Mega is of roughly equal strength to Mega as it is a variant Mega form (on the side, so to speak), while Burst Mode is usually more powerful than either.
The player may carry two Mercenary Digimon in addition to the Starter Digimon, for a total of 3 on the field at any time. A 4th slot for Mercenary Digimon can be unlocked via CashShop item in both kDMO (Jan 1, 2014 update) and gDMO (Feb 25, 2014 update).
