The personification of the British light cruiser Dido (Pennant Number 37), named for the first queen of Carthage according to Greek and Roman legend. As is typical of many Royal Navy light cruisers, Dido is portrayed as a maid, with white hair (though longer and with a more blue-ish tint) and purple eyes. Her figure is similar to her sister ship, Sirius, with large breasts that may even outdo her sister's in terms of size. To emphasize this, her maid dress even comes with a cleavage cutout showcasing her underboob. She is also frequently shown holding a doll of Sirius.
Her personality is very dedicated, though she often fears being abandoned by the Commander and left to her own devices.
