The Destruction of the USS Maryland

The Machine Empire, despite being a 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, then this will happen:

The Galaxy-class Federation starship USS Maryland encountered a temporal vortex in the Alpha Omega star system. The flagship of the army of the Machine Empire emerged from the vortex. The Machine Empire had Decepticons, Cybermen, Borg, Toclafane, Daleks, Cylons, Replicants, and Terminators. The Machine flagship attacked the Maryland. A fierce battle ensued. The Machine flagship damaged the Maryland's starboard warp nacelle, causing it to leak drive plasma. The starboard nacelle flared, throwing the Maryland into a spinning motion, out of control. The Maryland's captain said "All hands abandon ship, repeat, all hands abandon..." Then the USS Maryland exploded, killing all aboard.
