Dora-nichov is of the holders of 'Bestfriend Telecard' and the most mysterious member of the group. Despite being the second smartest amongst The Doraemons, Dora-nichov is very reserved and quiet. He's extremely sensitive to the cold, which make him uses the four-dimensional muffler (四次元マフラー) covering his face as an alternative to the fourth-dimensional pocket.

Like El Matadora, Dora-nichov has his own super hero form, known as Super Wolfman. In this form, he wears a suit similar to Superman's suit, but instead of an S, he has a W on the front. He is, of course, in his werewolf form and wears a cape around his neck.
