Dark One Deals

Fairytale Deals
Throughout the realms, Rumplestiltskin became known as a being of great power and fear, able to grant a person's deepest wishes and darkest desires with magical deals that proved to be worse than he would intially proclaim. These deals appear to transcend into the Storybrooke reality as well, with Rumplestiltskin's counterpart Mr. Gold retaining a similar disposition for swindling people in desperate situations. In either reality, it appears that Rumplestiltskin always benefits in the long term through his deals, despite short term set-backs brought about by certain individuals.

The Dark Curse in Exchange for Riches and Comfort
In exchange for the secret to completing the Evil Queen's Dark Curse, Rumplestiltskin demanded riches and comfort in the real world of Storybrooke, and that the Evil Queen has to give him anything he asks for as long as he says "please."

In the episode That Still Small Voice, it is revealed that Rumplestiltskin had a business relationship with Jiminy Cricket, who would bring him possessions stolen by his parents during their travels as puppeteers in exchange for Rumplestiltskin's gold thread. One day, sensing that Jiminy had become disillusioned with being forced into a life of deceit and thievery, Rumplestiltskin offered him the chance to escape by giving him a magic potion that would take care of his parents for good. In return, Rumplestiltskin only asked that he be given Jiminy's parents after they had taken the potion, as it would count as his fee. However, Jiminy's plan backfired when his parents switched Rumplestiltskin's potion with a bottle of rainwater they had planned to give to another swindled couple. After learning that the couple had been turned into marionettes through the potion, Jiminy left his parents and made another deal with the Blue Fairy to become a cricket in order to mentor the couple's now orphaned son, Geppetto. Meanwhile, Rumplestiltskin, true to his word, took possession of the marionettes, who were later shown to be owned by Mr. Gold in his pawn shop in Storybrooke.

Cinderella's Night at the Ball in Exchange for her Firstborn

She tells Rumplestiltskin that she is pregnant with twins, and she will give both children to Rumplestiltskin in exchange for good crops in Thomas' kingdom, if Rumplestiltskin will sign a contract using the red quill. (The deal is a ruse; Cinderella is not pregant with twins.) Rumplestiltskin warns Cinderella that she should not try to trick him because "all magic comes with a price," but he signs the contract nonetheless. The quill freezes Rumplestiltskin and he is imprisoned in the dwarves' mines. However, Prince Thomas mysteriously disappears. Rumplestiltskin tells Cinderella that the Prince wouldn't return to her until Rumplestiltskin's original deal was honored.

When King George asked Rumplestiltskin for help, Rumplestiltskin brings him the son's twin brother in exchange for the location of the Fairy Godmother, elaborating that her death in The Price of Gold happened as a result of this particular deal.

Rumplestiltskin later broke this deal himself, releasing Belle from their arrangement after suspecting that she was in league with the Evil Queen planning usurp his power. This assumption turned out to be false.

He gave Regina the Looking Glass which she later pushed Cora into. In exchange, he only replied that he know that someday she would do a favor for him. This "favor" is highly casting the Dark Curse (due to the fact that Rumple, at that time, didn't have neither Baelfire or Belle, as the heart of "the thing you loves the most" was a key ingredient for the curse), sending him to our world in order to find his son.

Admitting defeat, Gold tells her his name is Rumpelstiltskin, revealing that he remembers everything from his previous life. Regina then gives back the teacup that Belle chipped, Rumplestiltskin's only memento of Belle. After this exchange, Gold tells Regina that this changes nothing as he still has more power than she does in Storybrooke. Although this is true, it is revealed that Regina is holding Belle's Storybrooke counterpart hostage in what appears to be the mental ward of Storybrooke's hospital.
