Can Beast Balls be Passed Down through Breeding in Pokémon?

No, it is not currently possible to pass down beast balls to bred Pokémon in any core series game. The beast ball is a unique poké ball with a higher catch rate against Ultra Beasts at the cost of an extremely low catch rate for normal Pokémon.

When breeding two Pokémon, the female‘s poké ball type has a chance to pass down to the offspring. However, specialty balls like beast balls, master balls, and cherish balls cannot inherit their distinct effects. So breeding something caught in a beast ball will result in the standard poké ball for children.

How Does Passing Down Poké Balls Work?

Normally, Pokémon have a 50/50 chance of inheriting either parent‘s poké ball when bred together in a daycare center:

However, certain specialty ball effects cannot pass down at all:

• Beast Ball
• Master Ball
• Cherish Ball

The offspring of these will always revert to a standard Poké Ball instead with no bonuses.

Why Prevent the Beast Ball Specifically From Breeding?

Game Freak specifically prohibits inheriting the beast ball likely for balance reasons. Its 5x catch rate against Ultra Beasts would be extremely unbalanced against normal Legendaries:

• Ultra Beasts cannot breed, preventing exploitation
• Beast ball Legendaries would badly imbalance gameplay
• Maintains the ball‘s intentional specialty for Ultra Beasts

Additionally, the beast ball is intended as a post-game challenge reward. So for gameplay longevity, they restrict replication through breeding as well.

What WOULD Happen if Beast Balls Could Breed?

If the games did allow passing down the beast ball, there would be some fascinating implications:

• Players could stock up on far more beast balls more easily
• Catching normal Legendaries like Mewtwo would have ~30% base catch rate
• Players may explosivesly target shiny Legendary beasts at higher odds
• Competitive players would greatly value bred beast ball Pokémon
• Rarity of beasts balls would diminish, removing the specialty

Some speculate Game Freak may allow this in a future game installment to shake up gameplay. But for now, they severely limit beast ball supply and inheritance.

Contrast With the Master Ball Pass Down Restrictions

Another specialty ball, the master ball, also cannot pass down breeding. And the reasons align closely with the beast ball restrictions:

• Maintains extreme rarity of master balls
• Avoids easy catches of high value Legendary Pokémon
• Does not force players to breed solely for master balls
• Encourages conservational use of the item by trainers

So for both the beast ball and master ball, restrictive breeding mechanics preserve intended imbalance and value.

Evidence Supporting Lack of Beast Ball Inheritance

According to official developer Game Freak in Pokémon Sun & Moon, the beast ball cannot pass down:

"The Beast Ball is the only Poké Ball designed especially for Ultra Beasts—it boasts an even higher catch rate against these Pokémon. And while you can‘t breed Ultra Beasts, you‘re also unable to pass Beast Balls down through breeding."

Likewise, Bulbapedia‘s detailed breeding mechanics guide does not list the beast ball as inheritable. So all official and vetted resources confirm no capacity for passing beast balls down.

Availability of Beast Balls in Scarlet/Violet vs. Past Games

One alleviating factor is Pokémon Scarlet/Violet added renewable ways to obtain beast balls through vendor trading:

So while inherited breeding is still prohibited, beast ball supply evolves in each installment.

Speculation on Future Changes to Pass Down Rules

There is always speculation on whether Game Freak may shake up breeding mechanics in new games. Some popular theories include:

• Allowing beast/master balls to pass down at very low rates
• Special Rare Marks could block passing down special balls
• New regional Ultra Beasts could enable breeding bonuses
• Future new Poké Ball types may also show restrictions

But currently, no game enables passing down the valuable beast ball or its catch rates.

Conclusion

In summary, it is conclusively not possible to pass down beast balls through breeding in any mainline Pokémon video game. Game Freak specifically prohibits breeding inheritance to maintain balanced usefulness for Ultra Beasts and encourage conservational use.

While the supply and availability of beast balls slowly improves with each new title, the breeding limitations remain intact. So trainers must use their precious beast balls sparingly if they wish to catch multiple Ultra Beasts or Shiny Legendary Pokémon at higher odds. We can only speculate if inheritance mechanics may change in future Generations!
