The latest Pokemon CoroCoro leaks have arrived for December, and while it does not provide too many new updates, there are a few noteworthy details.

On Tuesday, various Pokemon portals began to upload the latest CoroCoro leaks. This month, the majority of the leaks focus on Legendargy Pokemon like shiny Yveltal and shiny Xerneas. But if you're careful, you'll notice a new Zygarde core that has a blue abdomen instead of the red abdomen.

"I think there might be even more, at least five," commented reddit user XeverstonedX. "Look at this. The complete Zygarde is holding five 'cores' in its chest."

Given that previous artwork has not featured Zygarde with the five cores in its chest, there is bound to be more we do not know about this mysterious Pokemon.

According to the official Pokemon website, Zygarde Complete Forme is the "perfect Forme that Zygarde takes when the Core gathers 100% of the Cells."

"When the ecosystem is under threat, and the Core concludes that the 50% Forme will be unable to deal with it, the Core takes on the Complete Forme. Its power is said to be greater than that of the Legendary Pokémon Xerneas and Yveltal!"

Based on the various Formes of Zygarde, there appears to be further connections to Norse mythlogy, this time based on Loki's children.

"I don't know if this has been posted before, but has anyone noticed that the new forms represent Loki's children, with Zygarde 10% being Fenrir, Zygarde 50% being Jörmungandr and Zygarde Perfect as Hel," wrote reddit user 4000lux.
