USS Missouri (BB-63) ("Mighty Mo" or "Big Mo") is an Iowa-class battleship and was the third ship of the United States Navy to be named after the U.S. state of Missouri. Missouri was the last battleship commissioned by the United States and is best remembered as the site of the surrender of the Empire of Japan, which ended World War II.
- Missouri's personality is very focused on her role as the ship used to negotiate the surrender of Japan, as she handles a lot of documents with ease. She takes her role as a museum ship very seriously and enjoys it thanks to her skills in writing and teaching.
- She often talks about how bored she is of training exercises, as she was forced to undertake many in between her deployments.
- It is also mentioned that she had no equal opponent in training which made it boring for her. She was the only ship of the Iowa-class to remain commissioned in the Navy after World War II, and so she never had an "equal" challenge of facing her sisters in combat.
- Missouri mentions that she wanted to fight hand in hand with another ship which is most likely her older sister, Iowa. Despite being deployed in the same conflicts, the two ships never directly participated in the same battles.
