Hammer

Hammer serves as the vendor to Soma’s journeys and is generally a less serious character in the Sorrow subseries. He is initially a soldier in the United States military, and he is sent to the Hakuba Shrine in 2035 to investigate the events there. Of course, he is magically transported into Castlevania alongside all the other characters, and he must be rescued by Soma Cruz from one of the castle’s boss monsters. Hammer reveals that he has been thinking about quitting the army and opening up his own shop, and he decides to set up a stall at the castle’s front gate to sell Soma powerful items and potions he had found previously for gold that Soma racks up during his quest in the castle. He makes deals with Soma throughout the 2035 event, and he is eventually transported out of Castlevania alongside everyone else once Soma is victorious.

In 2036, Hammer has left the military and is acting as an independent merchant. He locates the giant Castlevania replica constructed by the cult that is after Soma, and Soma soon makes him give that information so that Soma can find the castle and take the fight to them. Hammer follows and decides to set up a shop at the base of the castle much like he did the year earlier, and Soma regularly comes to him to buy the potions and equipment Hammer acquired much like before. Hammer displays a not-so-subtle crush and affection for Yoko Belnades, who has a shop facing his nearby, and Soma must contend with their concerns for each other the entire game.

According to a text dump of Dawn of Sorrow, Hammer was likely to be included as a playable character in the hidden Julius Mode. The Dawn of Sorrow Julius mode is very much like Castlevania III - Trevor/Julius Belmont, Sypha/Yoko Belnades, and Alucard. Thus, Hammer would have been Grant DaNasty's counterpart (the two have a similar physical appearance).

Aria of Sorrow
Soma meets Hammer after defeating the Great Armor in the Library. He introduces himself and then heads for his shop near the entrance. From this point on, Soma can talk with Hammer whenever he is at the entrance. Hammer sells a variety of maps, use items, weapons, and equipment. More powerful items become available as Soma defeats certain bosses or meets certain conditions. The most expensive item at Hammer's shop is the Soul Eater Ring, which at 300,000 gold, is 20 times as expensive as any other item at the shop. Soma can sell almost any item he has in his inventory for half of its purchasing price (does not include Souls). mCJUwrfsLZ4 Soma meets Hammer (at about 4:20)

Dawn of Sorrow
Hammer sets up shop again in Dawn of Sorrow. His shop is located in the Lost Village right across from Yoko's shop and is available right after the first boss battle against the Flying Armor. He sells much the same kind of stuff that he did in Aria of Sorrow. One new thing is that he became interested in a cryopto-zoological magazine, which can give hints on how to find rare monsters. Other issues can be found elsewhere in the castle. Most basic weapon types in their class are available in Hammer's shop, which can be fused into greater weapons at Yoko's shop. Some more advanced weapons can also be found. Of note is several kinds of throwing weapons and guns that cannot be fused are now available at the shop. The Soul Eater Ring is still the most expensive item at his shop. 3eU5k0KctqM Soma meets up with Hammer Maps:
