Hua-Shen

The Hua-Shen was a giant sea creature used by the Sea Devils to "hunt", "seek" and "feast" in the oceans and seas of 19th century China. It was allowed to roam free to feed on unsuspecting sailors and bring them down below the depths to its masters.

Zheng Yi Sao initially described the Hua-Shen as a myth. (TV: Legend of the Sea Devils)

Description
The Hua-Shen resembled a large fish similar to the sea creature found by the Twelfth Doctor and Bill Potts in the River Thames during the last Frost Fair of London 1814. (TV: Thin Ice)

In particular, it had large dorsal fins that jutted out of the water; ten orange eyes split between both sides of its head; and hundreds of razor-sharp teeth lined up in multiple rows in its mouth. This made it extremely similar to a unique Myrka found in the Pacific Ocean in 1886; placed there by the Sixth Doctor to attack a ship with Madame Vastra, Jenny Flint, Rose Tyler and the Ninth Doctor onboard, resulting in them becoming shipwrecked on an island. (COMIC: The Lost Dimension)

It was also similar in appearance to another creature, equally under the control of the Sea Devils, found roaming around South America in the early 1600s. (COMIC: Devil of the Deep)

Abilities
It had the ability to resist and catch multiple cannonballs, as well as spit them back at full speed; and would often rise up from the depths with a wide-open mouth to devour and catch its prey. (TV: Legend of the Sea Devils)

Behind the scenes
The name "Hua-Shen" could be derived from "huà shēn"; the Pinyin spelling of the Chinese word 化身 meaning "incarnation" or "reincarnation".
