8472 Mother Dreadnaught
This is a supremely unbalanced ODF mod for species 8472. It creates a Dreadnought with the impulse speed of a scout, weapons exceeding the normal mother and shields twice as powerful as the mother.
Oh, and I almost forgot its got a tachyon grid built in as well as being capable of creating embryos. This could seriously upset game balance if an equivalent is not installed for other races.
