• Characterisations. The following conditions are equivalent:
    1. The functor $F$ is pseudoepic.
    2. For each $\mathcal{X}\in \text{Obj}\webleft (\mathsf{Cats}\webright )$, the functor
      \[ F^{*}\colon \mathsf{Fun}\webleft (\mathcal{D},\mathcal{X}\webright )\to \mathsf{Fun}\webleft (\mathcal{C},\mathcal{X}\webright ) \]

      given by precomposition by $F$ is pseudomonic.

    3. We have an isococomma square of the form
      in $\mathsf{Cats}_{\mathsf{2}}$ up to equivalence.
