How many black star dragon balls are there?

There are seven Black Star Dragon Balls in the Dragon Ball GT series. Similar to the regular Dragon Balls, the Black Star Dragon Balls are spherical objects with stars inside them, but they are much rarer and more dangerous. When gathered and used, they summon Black Star Shenron, a powerful dragon who can grant a wish. However, unlike the regular Dragon Balls, the Black Star Dragon Balls are scattered across the entire universe once used.

Key Features of the Black Star Dragon Balls:

1. Seven Dragon Balls: Just like the regular Dragon Balls, there are seven Black Star Dragon Balls, each with a number of stars inside them, from 1 to 7.
2. Black Star Shenron: When the Black Star Dragon Balls are gathered, they summon Black Star Shenron, a dragon with the ability to grant a single wish, though the consequences of using the Black Star Dragon Balls are much more severe than those of the regular Dragon Balls.
3. Dangerous Consequences: After a wish is made using the Black Star Dragon Balls, they scatter across the universe, and the Earth will eventually be destroyed unless they are gathered again within a year. This introduces a major risk for anyone using them.
4. Different From Regular Dragon Balls: Unlike the regular Dragon Balls that can only be used on Earth, the Black Star Dragon Balls can be found across the entire universe, making them much harder to collect.

Conclusion:

In total, there are seven Black Star Dragon Balls, each representing a different star. These balls are part of an important storyline in Dragon Ball GT, where the quest to recover the Dragon Balls spans across the universe and leads to various adventures.
