Fractal Code

The idea of fractal codes was used in Digimon Frontier. Fractal codes are apparently bit's of data from Digimon that could be obtained when a Digimon was destroyed. Mercurymon is one of the Digimon who best demonstrates the absorbtion of Fractal codes. In the manga When Seraphimon was destroyed, Mercurymon was able to absorb his Fractal code, thus resulting in his ability to digivolve into ShadowSeraphimon. The Beast Spirit of Steel, Sakkakumon, also demonstrates the use of Fractal codes, one of his attacks is based on Fractal codes.Rumble blend#1-10 attacks his opponents with an element of one of his spheres(this attack only works if he has absorbed a Fractal code of a Digimon that had the same element of the attack).

I think some FRACTAL codes make more parts of the digiworld reaper
