When it comes to describing a group of people with diverse backgrounds and personalities, the phrase "motley crew" is often used. However, there are many other synonyms that can be used interchangeably to describe such a group. "Ragtag bunch" is a popular alternative, as is "assorted gang" or "eclectic team." Other options include "hodgepodge squad," "diverse crew," "mixed bag of individuals," and "multicolored troupe." All of these phrases effectively convey the idea of a group of people who may seem disparate at first glance but who come together for a common purpose.
