The Ukrainian Ironbelly is a type of dragon from the Harry Potter theme. One specimen of this dragon was used to guard several high-security vaults, including the Lestrange Vault, at Gringotts Wizarding Bank. It was encountered by Harry Potter and his friends when they infiltrated the bank in 1998, (in order to obtain a horcrux) although it is likely the dragon had been guarding the vaults for a long time prior to this.
It is unknown when exactly this particular dragon was placed to guard the vaults it was assigned, but it is known that during this time it was trained to fear the sound of the Clankers as it expected pain upon hearing it, causing it to retreat and allow those with using the Clankers to access the vaults. This was most likely achieved using the process of classical conditioning. The dragon was aged and half-blind by the spring of 1998.
1998 Break-in of Gringotts
As Harry Potter, Ron Weasley, and Hermione Granger had been planning to break into the Lestrange Vault for a few weeks ahead of time, they fully expected to find the dragon and were able to use the Clankers (with the help of Imperiused goblin Bogrod) to drive it away and get into the vault.
After the goblin Griphook abandoned them and they were carried out of the vault in a cascade of treasure, Harry, Ron, and Hermione jumped onto the back of this dragon in desperation to avoid the charging wizards and goblins. Hermione severed the dragon's chains and used a Gouging Spell to help the dragon carve its way out of the tunnel and toward the surface. The other three pitched in, and the dragon crashed through the Gringotts hall, out into Diagon Alley, and took off.
The trio soared on the back of the dragon for a while, but finally jumped off into a lake as the dragon lowered it's flying height nearer to the water's surface to get a drink. Although Hermione expressed concern for leaving the dragon in the wild, Ron was confident it would be able to defend for itself without difficulty. It is unknown what happened to the dragon afterwards.
