How many oni masks are there in Jackie Chan Adventures?

While there's not a specific number of Oni masks mentioned in Jackie Chan Adventures, there are several throughout the series.

Here's why it's difficult to pinpoint an exact number:

* The Show's Concept: The show features a vast array of mystical artifacts, including many masks with varying powers and origins.

* Recurring Themes: Oni masks are recurring symbols representing demonic power.

* No Central Repository: The masks are often scattered, hidden, or passed down through different lineages.

Examples of Oni Masks in the Show:

* The Mask of the Oni King: A powerful mask possessed by the Oni King himself.

* The Mask of the Demon Lord: Wielded by the demon lord, Dai Tengu.

* Various Lesser Masks: Many other masks with lesser demonic powers are used by villains or acquired by Jackie and his friends.

Therefore, instead of focusing on a specific count, it's more accurate to say that "numerous" Oni masks exist in the world of Jackie Chan Adventures.
