feet of clay
1
a serious flaw or weakness in one's character that other people are not aware of
The idiom "feet of clay" originated from the biblical book of Daniel in the Old Testament, where a statue with a head of gold and feet made of a mixture of iron and clay symbolizes a powerful yet flawed kingdom. This idiom suggests that the person or thing in question has a vulnerable or fragile aspect that is not immediately apparent. It can be employed when discussing individuals, institutions, or even objects that initially seem flawless but later reveal their imperfections or shortcomings.
