Bullet Bills are dangerous, but predictable. They are essentially projectiles, without any intelligence, even though they display some animal-like characteristics. There are some more intelligent Bullet Bills which can follow their intended target to a degree, but most are relatively unintelligent.
While Bullet Bills and their cannons are manufactured by the Koopa Troop, Booster, who loves tinkering with machines, has also managed to construct some of his own.
EVOLUTION:
Bullet Bills first appeared in Super Mario Bros, and have become one
of the series' most commmon enemies since then. Originally, they were
bullets with eyes and arms, an appearance which remained the basic design
for quite a while, although in some cases they were drawn with mouths.Finally, in Super Mario World 2, they gained the sharp-toothed smiley face that drawings often showed them with. All of these designs were carried on and combined in Super Mario RPG, where they had both arms and the smiley face.
Some might begin to think that Bullet Bills were starting to change over time. The problem is, Super Mario World 2 takes place long before any of the other games, chronologically - and at any rate, Bullet Bills can't really "evolve" as they are mechanical. Most scientists agree that there must simply be different designs for these monsters.
Super Mario 64 and Yoshi's Story continued on with Bullet Bills that have mouths, but no arms. Of course, to confuse the situation, Paper Mario put them back to the "arms with no mouth" style. Experts now believe that there are simply multiple designs for Bullet Bills, most with either arms or mouths, that are used interchangeably by the Koopa Troop and other designers.
