We introduce and study the concept of characteristic for metrics. It turns out that metrizable spaces endowed with an $L^*$-operator which admit a metric of characteristic zero play an important role in the theory of fixed points. We prove the existence of such spaces among infinite-dimensional linear topological spaces.
