As for Joker, it depends on how strong s/he is compared to the other In-Verse characters then compare all the In-Verse characters to how they'd fair against Siegmar (in non Fallen one form). Of the three Fallen Ones known in the Monstrum Tower series, Siegmar Umbra is the weakest in terms of power compared to Roland (Astolpho's friend) and Cythraul.
