What role does the Coalition of Planets play in protecting monster girls and other vulnerable alien species in *Invincible*?

The Coalition of Planets serves as a loose alliance of various alien races, including many monster girls, formed to defend themselves against threats like the Viltrumites and human exploitation. While often hampered by internal conflicts and limited resources, the Coalition provides a degree of protection and advocacy for its members, offering a space for cooperation and resistance against common enemies. It's a flawed but vital organization for many marginalized alien species.
