(Capcom's primary storyline)
"Got somethin' that might interest ya'!"
— One of the lines spoken by the Merchant upon being interacted with.
While the Merchant primarily functions as a shop for players, he still "acts" as a character.
He is a weapons peddler who dresses in a long, black coat. A pale blue flame marks the locations of his shops, and he appears capable of traveling great distances in the blink of an eye. He carries a wide selection of weapons inside his huge backpack and coat. It is obvious from his appearance that he is a Ganado, but he doesn't seem to regard outsiders as a threat, and will deal with anyone as long as the price is right. No one knows how he gets his weapons, but his selection is enough to impress even Leon. He's very good at his trade, flattering the buyer with phrases like “The choice of an avid gun collector!” and “You'll need guts to buy that weapon!”
The Merchant reveals himself to Leon Kennedy after he wakes up in the house in the Valley by beckoning him from outside a window. When Leon goes around the outside of the building, the Merchant shows off his merchandise. Ada later runs into him inside the Cave, before he properly sets up his shop (which includes lighting a torch that emits blue fire). Leon crosses him in this same area when he is ready, and he greets Leon. He is also encountered by Ada Wong on various occasions. He was last seen before Leon fights Saddler.
The Merchant is interacted with by walking up to him and pressing the button that corresponds with the "TALK" action, the only exception being the first two times Leon encounters him and players "visit" him at the start of a new round.
The Merchant will appear at various points throughout the main game and Separate Ways, offering new upgrades and merchandise the further the player progresses.
The Merchant usually sets up a blue torch near him when he is in business, and most of the areas in which he appears are free of enemies, though they are not safe-zones.
The player can actually kill the Merchant. His body will not fade, and he will respawn in that specific spot after some time in Amateur and Normal difficulties, but not in Professional, where he will never come back.
The Merchant also has a bottle cap modeled after him. He is one of the regular prizes that can be won when playing Game C and his voice clip is him saying "Welcome!".
For the list of buying and selling prices, see here. When upgrading weapon Capacity, the held ammo resets to full.
There is a minor side quest involving destroying Blue Medallions for the Merchant at the beginning of the main game, which the player can start before even meeting him. Doing so will reward Leon with a specialized handgun.
- A card in Resident Evil: The Deck Building Game is modelled after him, called 'The Merchant'. He also appears in TEPPEN.
- According to the Beta Art works of "The Art of Resident Evil 5", another merchant-type character would have made an appearance, but was removed in the end. A leftover placeholder model for this Merchant can be found in the game's files. It has a flat orange texture and non-detailed model, with the Kanji for merchant (商 Shō ) being imprinted on the front.
- In the Resident Evil 6 Artworks book, there is a piece of concept art for unused EX Costumes that shows the Merchant on Leon's back.
- A different merchant appears in the iPhone game Resident Evil: Degeneration.
- In Resident Evil Village, The Duke appears as a merchant, who states to know the Merchant from Resident Evil 4.
