The USS Protostar NX-76884, the main ship in the CG animated series “Star Trek: Prodigy”, has already left its mark on the Federation, but certainly not as expected. A space prototype, the Protostar’s warp engine is complemented by the inclusion of an experimental proto-engine, powered by an actual small protostar. When fully powered, the proto-drive allows the spacecraft to travel to different quadrants around the galaxy in an instant, exponentially faster than warp-powered ships. Chakotay initially served as captain of the Protostar, until he and the ship were captured by the evil Diviner, with a ragtag crew of refugee children picking him up.
The scientific breakthroughs behind the Protostar alone justify its appearance on this list, but its role in the Prodigy season one finale makes it an infamous inclusion. Under the diviner’s control, the Protostar is infected with an advanced computer virus that acts as a Trojan horse for all Federation systems it interfaces with. Once infected, the defensive systems spin out of control and attack all other Federation targets in the immediate area. As the Protostar’s crew stops the spread of the virus, it infects and devastates a significant portion of the Starfleet armada, turning the Protostar into the deadliest ship in the fleet.
