Yamato/Yamato Main Computer

In canon, the Space Battleship Yamato is more than just a ship, she is a character herself. In Saga of a Space Battleship, she is given a voice in the form of the Main Computer. The character starts small with occasional lines through the entire series but will grow to vital importance in Act 3 onward. 

While monotone initially, the character will be given form later on and she is incredibly kind and soft spoken, despite being the embodiment of a warship.
