Many famous Dragon-type Trainers, including Clair and Lance, come from Blackthorn City.
According to a resident in Blackthorn, most Trainers in the city end up being Dragon-type specialists. This could be because of the Dragon's Den in the area and because the local Gym Leader is a Dragon-type Trainer.

Move Deleter and Move Tutor
A house is located in the southern part of the city, to the left of the Poké Mart.
In Generation II, the Move Deleter lives here, alone. For no charge, he will make a Pokémon forget a move it knows. The Move Deleter's service can be used to delete moves exclusive to Generation II, so that Pokémon can be traded to a Generation I game via the Time Capsule.
A clan of masters of Dragon-type Pokémon have lived in the city for generations. The masters built the Dragon's Den, a cavern with an underground lake that contains a shrine to Dragon Pokémon, as well as the elders of the Dragon clan. The entrance is located behind the Gym, across a small pond, while the main cavern seems to be located underneath the city itself.
It is inaccessible before defeating Clair in the Blackthorn Gym, as it is blocked off by a man in front of the cave, and then it must be traversed to finally obtain the Rising Badge. Clair and Lance appear for a Tag Battle if the player and rival have already battled at Mt. Moon.
The Ice Path is the only way into the town from the north. Route 45 is also reachable from the south of Blackthorn, but the steep mountain path means it can be used as an exit only. It is known for its numerous ice puzzles, which vary in size and difficulty. The Ice Cave is famous for its rare Jynx, but it has many other Pokémon as well. It is the only place in Johto where wildSwinub, Jynx and Delibird can be caught.
The Blackthorn Gym is the official Gym of Blackthorn City. It specializes in Dragon-type Pokémon. The Gym Leader is Clair. Trainers who defeat her receive the Rising Badge. It will be closed prior to Team Rocket's defeat because Clair is training in the Dragon's Den. After being defeated, Clair is so outraged by her defeat that she refuses to hand over the Rising Badge, forcing the player to go to the Dragon's Den before the Badge can be acquired.

Iris visited Blackthorn City in BWS02. During her visit, she found out that a Gible had been causing damage on the town by chewing off bits of benches, fountains, and such. Later, after saving Gible from falling off of a clock tower, Iris found out that Gible had wound up into the city by accident, and offered to take it away. She then met Clair, and together they took Gible to Dragon Holy Land. After Iris's battle against Clair at the Blackthorn Gym, Gible appeared again, showing that it wanted to come with Iris. Accepting the offer, Iris then caught the Land Shark Pokémon with a Poké Ball.
In the English versions of Pokémon Gold and Silver, if the Dratini in one of the houses is interacted with and the Coin Case is used immediately afterward, a glitch will be triggered. This causes the Coin Case's display to change to "Which move?he pp of" permanently, unless the game is rebooted without saving.
