Mastemon

Mastemon is an Angel Digimon. It is an Angel Digimon who manipulates light and darkness, and has the power to cross through space-time. Mastemon resulted from the DNA Digivolution of Angel and Dark Angel Digimon when a great crisis visited the Digital World and controls the forces of the Angels and Dark angels that are called through the gate from another Digital World. Although it is a DNA Digivolution of two conflicting types and shares qualities of both, it has a one-track mind.

Development
Mastemon was originally supposed to debut in Digimon World Re:Digitize as Mirei Mikagura's partner Digimon though this was unable to happen due to various issues. In order for Mastemon to have deeper meaning behind the concept of opposing attributes coming together, game producer Kazumasa Habu requested Mastemon follow the same two tone black/white color scheme of Lucemon Chaos Mode. Originally the design had Mastemon more bulky, equipped with armaments like cannons, but Habu didn't want a bulky design and instead wanted Mastemon to use its body as a weapon, so he requested the armaments be removed.
