Digimon Adventure V-Tamer 01
The Digimental is unknowingly held by Rei Saiba until her brother, Neo Saiba, takes it from her. It is initially depleted of energy, but Neo uses the energy released when his Alias III fight Tai to fill it with power.
The Digimental Code-F was used to digivolve UlforceVeedramon to UlforceVeedramon Future Mode, however in May 2018, UlforceVeedramon Future Mode and the Digimental Code-F were removed from Digimon Masters pending the resolution of a copyright issue. It was confirmed in November of the same year that they would not return to the game.
