Two-Tone is one of the original fifteen puppies of Pongo and Perdita. Like the rest of her siblings, she is kidnapped by Horace and Jasper for Cruella, and is brought to De Vil Manor to be made into a fur coat. She ends up escaping with the rest of the Dalmatians. In most of the tie-in material, Two-Tone is shown to be close to her brother, Whizzer. She is also shown to have a love of music and is a bit of a tomboy, to contrast with Jewel's girly personality.

Despite being a minor character, Two-Tone is one of the most popular characters among the fandom.
