After the Maniax's attack on the GCPD left Sarah Essen dead, Nathaniel Barnes was assigned to the position of Captain and he and Gordon worked together to rid the department of corruption whilst assembling a Strike Force too. After a chain of events lead to Gordon being targeted by a resurrected and delusional Theo Galavan, who became the ancient warrior called Azrael, the GCPD was once again attacked by the latter and Barnes was seriously wounded, leading to Bullock becoming acting-Captain.
