A fanfic crossover in which Rockman, from the Rockman Exe version or Battle Network Series, accidently end up in the Digimon World, due to a portal, and while searching for a way to return to his digital world sees Sora Takenouchi and Mimi Tachikawa in danger being attacked by BlackWarGreymon and decides to help them.

The enemy ends up being too strong and fast and Megaman recieves some demage and loses his helmet during the battle. fortunately Megaman had some chips stored in memory but must use them wisely so he remembers a technique with the VarSwrd/Variable Sword that allows him to create Sword Energy Waves embeded with different elements like Water, Electricity,Fire and Wood; he decides to use the enemy´s speed against itself and releases Elemental Sonic Booms at the right time.

Note: In Megaman Battle Network 3 you can actually do this Elemental Sonic Booms/Waves with the VariableSword.
