Search for the Bat-Trophies (Earth-Prime)

Search for the Bat-Trophies was the Bat-Team's pursuit on the trophies that were stolen by a brainwashed Kate Kane.

Background
After the Skirmish in the Batcave, "Circe Sionis" stole a series of weapons belonging to Batman's enemies and gave them to Black Mask. The trophies were later scattered all over Gotham River and picked up by visitors of the river.

Extensively Search
While Luke Fox operated as Batwing, Batwoman did not search alone for the trophies. Over the next few months, they were able to restore Clayface's mud, Penguin's umbrella, Catwoman's whip, King Shark's tooth, Bane's Venom tank, Scarecrow's Fear Toxin, Joker's Acid Flower, Condiment King's Condiment Gun, Mask of Phantasm and false Poison Ivy's vines. However, Joker's Joy Buzzer was kept by Renee Montoya, with her keeping it a secret from the Bat-Team.

Mad as a Hatter
After acquiring Poison Ivy's vines, the Bat-Team noticed Mad Hatter's hat in social media and began pursuing it. They soon discovered that it fell into the hands of Liam Crandle, an Alice fan who later attacked Gotham City University and mine controlled Mary Hamilton to kill her professor. Thankfully, she was able to find a way with Sophie Moore to break the control and bring him back. During the process, Ryan abducted Alice from Arkham Asylum for Crandle and successfully neutralized him.

Loose Tooth
Days later, the Bat-Team discovered multiple murders that matched the description of Killer Croc. They then investigated missing cases and found an underground sewer where the successor kept one of his victims. Albeit his father trying to convince Batwoman that he was not dangerous but was simply infected by Killer Croc's tooth, Steven murdered his father and attacked Batwoman, before being captured.

Freeze
The final missing trophy was Mr. Freeze's liquid nitrogen tank, which was pursued at the same time by a group of criminals. The criminals abducted Dee Smithy and Nora Fries, and forced them to create Mr. Freeze's cryogenic technology. The two were soon rescued by Batwoman, but unfortunately led to Batwoman being imprisoned in the Cryochamber. Thankfully, Batwing liberated her from the chamber and chased the criminals in the Batmobile. Eventually, both were able to retake the remaining Freeze Serum in the tank.

Aftermath
Though the trophies were all restored, Joker's Joy Buzzer was kept by Renee Montoya, unbeknownst to the Bat-Team. The buzzer later became crucial to the restoration of Marquis Jet's missing empathy, while the discovery of Poison Ivy's vines being false led to the Bat-Team's war with two Poison Ivys.
