— Mr. Hammer

Mister Hammer, also referred as Mr. Abramovici, is an antagonist at Gotham City. He is seen as Joker's one armed lieutenant in his army. After Joker's death, he later joined Black Mask with other Joker's thugs. He was mentioned to be with his conjoined twin, Sickle, performing at a Russian circus. However, they got into a fight and split up, literally.

Incident ReportsEdit

Before Arkham City IncidentEdit

Mr. Hammer was born as a conjoined twin along with Sickle in Russia, their mother died in childbirth and their father left them to a traveling circus where they performed in a animal wrangler/freak-show act. When the Joker caught wind of them and their reputation for brutality he sent Harley Quinn to recruit the pair into his gang.

Although the circus manager initially refused to give them up he was later found with a Glasgow smile carved into his corpse and the twins vanished. Once he had the twins in Arkham City Joker realized that they would be more useful separated and hired Thomas Eliot to do the deed, then deciding he only wanted a "right hand man" Joker decided to only keep Hammer while disposing of Sickle.

Arkham City Lockdown IncidentEdit

Arkham City IncidentEdit

One of the many whims Joker indulged in was watching Hammer beat those whom disappointed him to death, mostly the doctors who had failed him. When Batman infiltrated Joker's Steel Mill to find and interrogate Joker he was forced into a fight with Hammer after smashing open the doors to Joker's office. After a brutal fight against the Twin, Batman leaves him to confront Joker.

After the fight with Mr. Freeze, Batman returns to the Steel Mill to find and fight Joker. The Joker then sarcastically feign defeat before welcoming in a multitude of thugs, Mr. Hammer, and a Titan henchman. After defeating all of them once again, the building collapses on Batman due to a missile strike from Protocol 10. After the Joker's death, Sickle and Mister Hammer can be found together in the Steel Mill, talking about getting reattached.

If you scan them you will answer a Riddle. Although they are both enemies, they will both ignore you if you do anything.

After Arkham City IncidentEdit

After Joker's death, Robin goes to find Roman Sionis aka Black Mask has becomes the new gang leader in Arkham City. He goes through Black Mask's hideout, where he finds out that some of the Penguin's thugs joined him, and that Riddler is also helping Black Mask. Lastly, he goes into the Freight Train and beats through some of the Joker's thugs, that have also joined him. After getting through three cars, Robin comes to end to find a few thugs, Mister Hammer, and Black Mask blocking the control box. After beating the thugs and Mister Hammer, he leaves Black Mask for last, apprehends him, and destroys the control box that's moving the train. It can be assumed that he and his Brother were taken to temporary holding cells when the GCPD invaded the mega facility.

Before Arkham Knight IncidentEdit

Hammer and Sickle are both working for the Penguin by this point, who tasks them both with tracking down Scarecrow for his next plan. They succeed but Scarecrow captures them and tortures them for several days. When Scarecrow finally lets them go with a message for Penguin, they have been sewn back together and Mr. Hammer has to drag his brother to the Iceberg Lounge to deliver it. Penguin has them treated at the Arkham City Hospital and has to hire Tweedledum and Tweedledee to replace them while they recover.
