Mobi-chan is a very rare item from the 1940 series, and Capcom's earliest mascot. It appears as a chibi-style astronaut holding a shotgun. In every game it appears it will give a high score bonus when collected.
In 1943: The Battle of Midway, the Mobi-chan can be randomly found if the player quickly destroy the bridge of the battleship bosses before the boss explodes. Mobi-chan will then jump from the battleship and quickly move to one edge of the screen, giving the player a very brief time to collect him. Mobi-chan also appears in 1944: The Loop Master, where the player can find him by shooting specific portions of the background with the charged attack, granting a 1000000 points bonus when collected.
