Isabella Márquez is Dora's baby sister. She is a 1-year-old baby who has a twin brother named Guillermo. She appeared in various episodes of Dora the Explorer starting with Big Sister Dora. She wears a pink shirt that matches Dora's shirt, a white diaper, and a pink bow on her brown hair. In Happy Birthday, Super Babies, she wears a polka dotted dress. She appeared in Dora the Explorer games on NickJr.com and appears to also have super powers in the episode, "Super Babies". Like Guillermo, she remained unnamed until the episode "Dora's Jack-in-the-Box", where her name was revealed. She also appeared in the Dora and Friends series in which she was a little older and could actually speak in full sentences. She is voiced by Breanna Lakatos and Mia Sanchez.
