Dorami (born on December 2, 2114) is the sister of Doraemon. She is yellow and has ears that resemble a large red bow. She happens to be about 2 years younger than Doraemon. Strangely enough, they are siblings due to the fact that they shared half of the oil from a can. She lives in the 22nd-century Tokyo with Sewashi. She sometimes visits Nobita with a time machine when Doraemon is "off-duty" or to help Doraemon with something. She likes melonpan and is afraid of cockroaches. She is also shown to be a more advanced robot than Doraemon (Dorami is able to produce 10,000 horse power, in comparison to Doraemon's 129.3). Different from her malfunctioned brother, she's the smartest student during her school time, and has better skills in using gadgets. She also has her own spin-off manga. Her boyfriend is Dora the Kid of The Doraemons.
She is cobalt yellow in color and has ears resembling a large red bow. Her tail looks like a flower. She has a pink nose and pinkish cheeks in the 2005 anime.
