A great white bites a UFO aircraft in the Pacific and turns into a robo/shark hybrid.

An alien ship comes into earth orbit to drop a probe . The probe lands in the ocean only to be eaten by a Great White. Soon he turns into RoboShark much to the dismay of a Nuclear Sub in the area. Once finished he heads to Portland , (reality is Seattle) where he is already being tweeted of his actions , while RoboShark's actions are being followed by a news crew , while the daughter of the reporter he follows is the very same daughters whose tweet he is following. Now the US NAVY is after RoboShark while he burrows away through rock as well as water to the delight of his tweeters. Causing damage along the way only to have a final confrontation with the Navy at the iconic symbol of Seattle, the Space Needle.—stephen scialli

As an alien probe enters the Earth's atmosphere and penetrates the Pacific Ocean, a great white shark gobbles it down. As a result, an unexpected mutation occurs, transforming the aquatic creature of living tissue into a cold mechanised predator that is wreaking havoc on Seattle Harbour. Before long, the mighty U.S. Navy SEALs are after the mecha-shark, as the news of the destructive hybrid is spreading like wildfire on social media. Now, the local reporter, Trish Larson, and her teenage daughter, Melody, find themselves in the way of the metallic destroyer, in an attempt to stop the chaos. Can they save the city from the deadly Roboshark?—Nick Riganas
