Hydroid Medusa

"Your aqua droids are no match for the Mon Calamari. What makes you think these secret weapons you brought from your homeworld will fare any better?"
"They are half machine, half monster. We call them Hydroid Medusa. They are invincible."

―Nossor Ri and Riff Tamson on Hydroid Medusas^[2]

Hydroid Medusas were cybernetically enhanced jellyfish developed as bioweapons by the Karkarodons of the planet Karkaris during the Clone Wars.

Characteristics

Beautiful and dangerous at the same time, the Hydroid Medusas were large behemoths designed for underwater combat. They had on-board power plants and multiple electrified tentacles that could kill any biological being upon contact. However, they were at a risk of being short-circuited if near any electrical source.

History

During the last decade of the Galactic Republic, the aquatic Karkarodons from the planet Karkaris designed a biological weapon known as the Hydroid Medusa.^[1]

Commander Riff Tamson used a number of units in his conquest of the planet Dac for the Confederacy of Independent Systems, dropped onto the planet via Separatist landing craft. Invulnerable to blaster bolts and even lightsabers they proved a formidable opponent and forced the Republic and Mon Calamari resistance fighters to retreat with some casualties. Later Republic reinforcements in the form of the Gungan Grand Army arrived, with their boomas temporarily short-circuiting some of the Hydroid Medusas, though a fair number of them remained dispersed in the oceans after the Gungan army was captured. The battle was eventually won by the Republic.
