A rat-form demi-human merchant from the D Block of Nortune; like all other demi-humans, Hammer the Supplier was imprisoned in D Block because of Kaiser Sigmund's harsh anti-demi-human laws and policies. He was an associate of Ricardo Banderas, regularly doing Rico's laundry.
Hammer becomes a close ally to the protagonists, joining the crew of the Yggdrasil (sharing a room with Rico), and his "mad skillz" come in very handy whenever the group needs something difficult to procure. He even goes with them to Solaris, however while there he is turned by Krelian, who promises him a great reward if he can bring Elly back to him.
Mere steps away from freedom Hammer surprises the entire party when he pulls a gun on Elly and demands that she return with him back to Etrenank. Elly's mother Medena stepped in front of the gun and after repeated orders to move out of his way Hammer finally shoots her in the head. When the party escapes Solaris Hammer stays behind with Krelian but is not seen again until late into disc 2 of the game.
When he pops up again, we learn that Hammer was surgically grafted into the structure of a massive Wel-Gear and instructed by Krelian to destroy the party at the second Anima dungeon and again return Elly to him. His Wel-Gear form was a tough opponent and in spite of performing several self-modifications/mutations in battle he was unable to defeat Fei and Rico and return Elly to Krelian. He apologized to Elly, who was able to forgive him for everything that he had done, including killing her mother. Hammer died when his Wel-Gear fell into a massive ravine and self-destructed.
Hammer was an important factor in Rico's character development, and as part of the recurring theme in Xenogears of main characters losing friends, family and loved ones, and mourning their loss (as also mentioned in the lyrics of the song Stars of Tears). When Hammer still lived, his relationship with Rico could appear acrimonious, with Rico hurling insults and abuse in Hammer's direction. But Hammer's loss was very painful for Rico. Rico mourned for Hammer, angrily insisting that that it hadn't been Hammer's fault. For the rest of disc 2, Rico would fondly reminisce about the time he spent with Hammer, in stark contrast to how they were usually seen interacting when Rico still lived, indicating that the two had in fact been fairly close.
