While Clover is largely a silent protagonist, elements of their personality are shown or implied at several points. Generally, Clover has a warped sense of justice and a drive to do what they perceive to be the right thing. They tend to enjoy a bit of mischief and like to play along in bits. They're non-binary and don't have a gender or sex. Their main mission is to leave the Underground and avenge the fallen humans before them by killing most monsters they meet, but they are honorable.
