Dorami

Dorami is Doraemon's sister who is younger than he is. 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, Nobita's great-great-grandson. She is yellow and has ears that resemble a large red bow. 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). She sometimes visits Nobita with a time machine when Doraemon is "off-duty" or to help Doraemon with something. She also has her own spin-off manga.
