Which date will Mastemon's official Bandai artwork be released?

It's hard to tell. To begin with, it is still unknown whether the artwok that has been shown so far is the "official" one or the specific one from Cyber Sleuth. This one, at least, is likely to be released before the official launch of the game. Shadow Shinji (talk) 15:54, 6 February 2015 (CST)

Mastemon's Type[edit]

Does it seem strange that Mastemon is a lower-ranking Angel type Digimon as an Ultimate when it should have been a Principality type Digimon. Besides, it seems to be mastering the principle of Taoism and its name could reflect on that kind of mastery.-Kjfreeman72190 (talk) 16:33, 7 February 2015 (CST)
