Yatter-wan is a large, canine-shaped robot that appears in the Tatsunoko series Yatterman as a helper to Yatterman 1
and Yatterman 2
. The "wan" portion of its name is the Japanese way of mimicking a dog's bark.
Yatter-wan is able to consume special bone-shaped snacks that trigger a chemical reaction in his system, producing small hordes of robots that he deploys from his mouth. In the Yatterman anime
series, the robots produced varied from episode to episode as a "suprise robot of the week," that would generally prove instrumental in destroying whatever mecha that the Dorombo Gang were using in that episode.
Yatter-wan appears in both Tatsunoko vs. Capcom: Cross Generation of Heroes
and its update Ultimate All Stars
. In both games, it is part of Yatterman-1's super attacks. Its most powerful attack "This Week's Surprise Robot" stuns Yatterman-1's opponent before deploying a hor de of small robots that deal significant damage.
Yatter-wan also appears in Chun-Li's
ending in Cross Generation of Heroes, where it bursts through a wall in order to dispense tiny Chun-Li robots that subsequently explode, taking out a group of villains.
