Midgard Serpent (Viking Quest Movie)

The Midgard Serpent was a creature which appeared in the 2015 medieval-fantasy movie Viking Quest.

Description
The Serpent was, as its name might suggest, a monster resembling a gigantic snake or eel. Measuring over a hundred feet in length and broader than a man is tall, it was depicted as being a primarily a creature of the ocean which was capable of surviving on land, at least for short periods of time. With a finned head featuring a gaping maw lined with razor sharp teeth which was large enough to swallow a human whole, the beast also had the ability to breathe a gout of flames, as seen when it roasted King Wolven alive as he stood in defence of the princess.

History
Where the Midgard Serpent came from is never revealed in the film, although it was said to periodically require the sacrifice of a princess of royal blood in order to prevent it from destroying the world. After an evil king kidnapped Princess Tasya on her wedding day to offer her to the Serpent, a group of Vikings including her husband-to-be attempted a rescue. They were ultimately successful and one of the group, a man known as Erick the Blessed, killed the Serpent by piercing its hide with a long metal spear during a freak thunderstorm. Lightning struck the spear and caused the beast to explode, saving the world and future princesses from its depredations.
