Soitsu, Doitsu, Koitsu, and Aitsu

Soitsu, Doitsu, Koitsu, and Aitsu are characters from Parodius, a spin-off series of Gradius. They are little stick men flying on paper airplanes. Their actual names are commonly used in Japanese slang terms to refer to people who do not know (Doitsu = who, Koitsu = this guy, Soitsu = that guy - far from the speaker, but near to the listener - , and Aitsu = that guy - far from both chatters). They are represented by four colors: Red, Green, Blue, and Yellow, however it is unknown which stick man is which.
==Abilities==
From Gokujo Parodius to Jikkyō Oshaberi Parodius, the weapon system of these stick men is different to other playable characters in the game. Aside from speed up, once the part of a power meter is specifically chosen, each stick man can fire homing missiles, Round Shot, wave, grade up as a power up for Gradius-like multiple, and their only shield power up is aura. However, in Sexy Parodius, their weapon system has changed by replacing the homing missile power up into Strong Missile, except for Round Shot, Wave, Grade Up, and Aura, which are previously used in the predecessors of the series.
==Trivia==
* All four stick men make cameo appearances in the Yu-Gi-Oh trading card game, just like numerous Gradius crafts. However, they are rendered useless unless they are played together in pairs.
