At some point, Whelan became an agent of Crows Security.
Return of the Bat
Since the "return" of a bat vigilante, Whelan has been present and participated in several Crows missions.
During the Anti-Monitor Crisis, Whelan as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
Rise of Batwoman
Agent Whelan was entering a store just as two men were running out of it to find the store a mess. As he looked toward the counter, he saw known felon Ryan Wilder standing over the unconscious cashier, causing him to draw his gun, and arrest her.
Days later, Agent Whelan was with the other Crows as Jacob Kane had a meeting where he declared that the drug Snakebite would not take a hold of Gotham City, telling the Crows to find the leader of the False Face Society. After the meeting, Whelan presented Jacob with Kate Kane's phone that the NTSB had found; Jacob looked troubled and explained to Whelan that it would be easier for him to access the phone if Sophie was present.
Afterwards, an agent gave Whelan a photograph of the leader of the False Face Society, but Whelan told the agent that he would not present to Jacob a photo of a man with a black mask without knowing his true identity.
A few days later, Jacob approached Whelan with a photo of a painting created by Jack Napier and was told to locate the original. Whelan asked why was the word "Safiyah" written on the photo; Jacob told him that Safiyah may have been the person who kidnapped Kate.
- Peak of human physical condition: As a member of Crows Security, Whelan is likely in peak condition, given most of their agents are ex-Navy SEALs or Green Berets.
