Shenron

Shenron is a mythical dragon from the Dragon Ball series, summoned when all seven Dragon Balls are gathered. Once summoned, Shenron appears and grants a wish or multiple wishes, depending on the version of the story. He is depicted as a large, serpent-like creature with the ability to fulfill desires such as bringing people back to life or restoring worlds. Shenron's power is immense, but his abilities are limited by the rules of the Dragon Balls, and he typically appears for a limited time before vanishing once the wish is granted.
