Mister Hammer, also referred as Mr. Abramovici, was an antagonist in Batman: Arkham City. He was seen as the Joker's one armed lieutenant in his army. After Joker's death, he later joined Black Mask with other Joker's thugs. Mr. Hamer was mentioned to be with his conjoined twin, Sickle, and performed at a Russian circus. However, they got into a fight and split up, literally.
Before Arkham City Incident
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 the Abramovici Twins 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 Dr. Thomas Eliot to do the deed, then decided that he only wanted a "right hand man." Joker decided to only keep Mr. Hammer while he disposed of Sickle.
Arkham City Incident
One of the many whims that Joker indulged in was watching Mr. Hammer beat those who disappointed him to death, mostly the doctors who failed him. When Batman infiltrated the Steel Mill to find and interrogate Joker on Protocol 10, he was forced into a fight with Mr. Hammer after he smashing open the doors to Joker's office. After a brutal fight against the Twin, Batman left him unconscious to confront Joker.
After the fight with Mr. Freeze, Batman returned to the Steel Mill to find and fight Joker. The Joker then sarcastically feigned defeat before he welcomed in a multitude of thugs, Mr. Hammer, and a Titan Henchman. After he defeated all of them once again, the building collapsed on Batman due to a missile strike from Protocol 10. After the Joker's death, Sickle and Mr. Hammer could be found together in the Assembly Line at the Steel Mill, talking about getting reattached.
If you scanned them, you solved the riddle: "One assembled, do these two become one again?" Although the Abramovici Twins were both enemies, they would both ignore you if you did anything.
After Arkham City Incident
After Joker's death, Robin went to find Black Mask, who became the new gang leader in Arkham City. Robin went to Black Mask's hideout, where he found out that some of the Penguin's Henchmen joined him, and that the Riddler was also helping him. Lastly, Robin went onto the Freight Train and beat through some of the Joker's Henchmen, that had also joined Black Mask. After he got through three cars, Robin came to the end to find a few Joker thugs, Mr. Hammer, and Black Mask blocking the control box. After he beat the thugs and Mr. Hammer, Robin left Black Mask for last, apprehended him, and destroyed the control box that was moving the freight train. It could be assumed that Mr. Hammer and Sickle were taken to temporary holding cells when the GCPD invaded the mega facility.
Before Arkham Knight Incident
Mr. Hammer and Sickle were both working for the Penguin by that point, who tasked them both with tracking down Scarecrow for his next plan. The Abramovic Twins succeeded, but Scarecrow captured them and tortured them for several days. When Scarecrow finally let them go with a message for Penguin, they were sewn back together, and Mr. Hammer had to drag Sickle to the Iceberg Lounge to deliver it. Penguin had the Abramovici Twins treated at the Arkham City Hospital and had to hire Tweedledum and Tweedledee to replace them while they recovered.
- Mr. Hammer had a Hammer and Sickle "☭" tattoo, a symbol formerly that was used by his homeland, Russia, when it was the leader of the Soviet Union. It was also fitting for him and his brother, due to their names and weapons respectively.
- Mr. Hammer appeared in The Joker's Carnival Challenge Map along with Sickle.
- It took 50 hits to take him down. If you did so uninterrupted, you got the 50X achievement/trophy by fighting him alone.
