The Destruction of the USS Mayflower

The Machine Empire, despite being an empire, does not have any: Decepticons, Cybermen, Borg, Toclafane, Daleks, Cylons, Replicants, Terminators or any other mecha from other franchises. And I will not explain any of these creatures to them. Nor will I attempt to get them any.

You're right, because, if you do that, then the Galaxy-class Federation starship USS Mayflower will be destroyed!

The Galaxy-class Federation starship USS Mayflower arrived in the Alpha Omega star system! There was a temporal vortex in the system! Emerging from the vortex was a battleship. Aboard the battleship was the Machine army, comprised of Decepticons, Cybermen, Borg, Toclafane, Daleks, Cylons, Replicants, and Terminators! The USS Mayflower went to Red Alert, raised her shields, and armed her weapons! The battleship fired on the USS Mayflower! The USS Mayflower battled the battleship! The battleship severely damaged the USS Mayflower! The USS Mayflower's starboard warp nacelle was hit by the battleship, causing warp plasma to leak out of it! The starboard nacelle flared, throwing the USS Mayflower into a spinning motion, out of control! The captain of the Mayflower said "All hands abandon ship! Repeat, all hands abandon...!" The USS Mayflower exploded, killing all aboard!
