No, the Mythical Alpha Pokémon Cannot Reproduce

As an avid Pokémon expert and gaming guide writer, I get asked often by readers – can the mighty Arceus breed with Ditto or any other Pokémon? After thorough analysis into breeding mechanics across Pokémon games, the clear answer is no, the Mythical Alpha Pokémon Arceus cannot reproduce at all.

Why Arceus‘s Breeding is Restricted

Arceus falls into a special Egg Group known as Undiscovered, which consists solely of powerful Legendary and Mythical Pokémon. Game Freak intentionally restricts breeding for Pokémon in this group to preserve rarity, balance mechanics, and the mystical nature of these species in lore. Without restrictions, players could oversaturate the world with excess Arceus!

As you can see, free reproduction of these special Legendaries could disrupt gameplay and cause issues. That‘s why Pokémon have distinct Egg Groups limiting what can breed together, i.e.:

So while Ditto is able to breed freely thanks to its unique transformability, matches with Undiscovered partners like Arceus cannot occur. This keeps supreme beings like the Mythical Alpha sacred and challenging to obtain.

When Mythical Reproduction Works

Now you may be wondering – I thought Manaphy breeding produces Phione Eggs? So how does that mythical Legendary reproduce? Good question!

As hinted above, Phione is a special case where in-game lore provided an exception to typical restrictions. When bred with Ditto, the "Offspring Pokémon" Manaphy creates Phione Eggs – weaker but more abundant cousins at an 88.1% Egg rate:

Game developers allow this as Phione matches Manaphy‘s Fairy and Water 1 Egg Groups while providing players a slightly more obtainable version to use. Don‘t worry about Phione overrunning the meta either – stat totals clearly show the vast difference in power compared to the legendary Manaphy:

So in summary, while Ditto-Arceus breeding is impossible, the Manaphy-Phione case illustrates how Legendaries can rarely breed alternatives if game developers provide exceptions fitting lore backstories. But power levels remain clearly differentiated.

How Can Players Obtain the Mythical Alpha?

With egg breeding off the table, obtaining your own Adamant 31 IV Arceus requires luck securing one of these limited-time distribution events across Pokémon game generations:

I recommend players scope out big Pokémon news sites around Q1 each year when Mythical events commonly occur. Without access to breeding, grabbing Arceus gifts when possible is your best shot at reasonable IVs.

Alternatively, you can trade with players lucky enough from distributions to have extras. Competitive types may offer flawless versions, but prepare to pay premium price tags! Availability is guaranteed to stay restricted given Arceus‘s supreme lore standing.

Let‘s Recap This Breeding Question

I hope this deep dive on Egg Group mechanics, breeding exceptions, stats, and events gives my fellow passionate Pokémon experts plenty of insightful details on why no, Arceus cannot breed with any Pokémon, including Ditto. Restrictions appropriately match Arceus‘s mighty lore as the Alpha ruling above all other species.

While Manaphy can reproduce weaker Phiones through a special case, Game Freak otherwise locks down breeding for virtually all Legendary and Mythical beings. So take advantage of periodic Arceus distributions or trades in order to add the awe-inspiring Mythical Alpha to your powerful party! Feel free to ask follow-ups in comments below too.
