Introduction to the Ukrainian Iron-bellied Dragon: Do you remember the dragon guarding the vault in Gringotts? Diagon Alley also recreates its majesty. In "Harry Potter and the Deathly Hallows (Part 2)", Harry, Hermione, and Ron cooperated with the goblin Griphook to successfully enter the Gringotts Bank vault and steal the treasures hidden in the Belaclitus vault. The Hufflepuff Cup freed the dragon guarding the vault. This giant dragon burned the entire Gringotts hall to ashes with its blazing dragon flames. The last three people flew away from Gringotts Bank in the dragon, causing Gringotts to be in chaos.
