Vulture contacts Marco Xavier to deliver a weapon to a party held by Aldo Szuzi. Agents of Vulture plan to use the weapon against the Martian Manhunter.

When the killer strikes J'onn switches to the form of the party's host. He then defeats the killer. Later, J'onn is happy to learn that Vulture doesn't really know that flames are his only weakness.
