Koopa Troopas are turtle-like creatures who work for Bowser and are recurring foes for Mario and Luigi, though some have been allies to Mario in his quest to stop greater villains.
Appearance
Koopa Troopas are large, humanoid turtles. They usually have yellow skin, blue eyes, a shell, and shoes. The colors of the shell often vary among the species, but the two most common are green and red.
Personality
Although they work for Bowser, they are not very malicious, as they are mainly trying to do their job. While foes with Mario, they are willing to put aside their grudge to have fun with the plumber and his friends. They have even directly opposed Bowser in games like, Mario Party and Mario Baseball.
