Forum:Digimon Fusion digimon

so i am looking threw the metals i have obtained well playing digimon:CS and i realised something about the digimon in Fusion. of all the digital worlds the ones in fusion have the weakest of the digimon as they are unable to digivolve and this means they are unable to gain ABI a vital status of digimon (in games) that allows them to gain greater power and levels of digivalution.
