The Blaster is an energy firing pistol that is kept often by Fox, Falco, and Wolf. James McCloud is seen with what is presumably a blaster in the prologue to Star Fox 64, and players can use the blaster in the game's multiplayer. During the events of Star Fox Adventures, General Pepper restricts Fox from using his blaster. In Star Fox: Assault, it served as the basic weapon for all of the characters in the game. It was much larger in Assault, comparable to a small carbine weapon rather than a pistol, and was also able to be charged.
The blaster was the main weapon of every character in Assault. Similar to the Arwing's lasers, the blaster could charge. It had a semi-lock, not a full lock, which meant that the targeting reticle would slightly lock on to the foe and it would change your direction.
Super Smash Bros. series
Throughout the entire series, Fox has used his blaster as his standard special move. In the first game, Fox fired it at a slow rate and it made those hit by it flinch, stopping them in their tracks. In Super Smash Bros. Melee and Brawl, Fox could shoot it more rapidly and the shots did not make the opponent flinch at all.
In Super Smash Bros. Melee, Falco appeared as an unlockable character. His blaster was similar to Fox's blaster from Super Smash Bros, only it fired at a much slower rate of fire, hits for more damage than Fox's blaster, and causes the enemy to flinch. It is also of note than when using his blaster, Falco crosses his arms and holds the blaster parallel to the ground, rather than wielding it in a more orthodox manner. In Super Smash Bros. Brawl, Falco's blaster fire is blue instead of red.
In Super Smash Bros. Brawl, Wolf uses a customized blaster. It has a small bayonet at the end of the bottom of the gun, which he uses when pulling out the blaster prior to a shot. His shots move slow, are incapable of being fired in rapid sequence like Fox or Falco can, and doesn't travel as far as Fox or Falco's, but they are much more powerful. His blaster fire has a green color, and the shots are shaped more like bursts rather than beams.
