Other Sophie is a supporting character in The Epic Tales of Captain Underpants.
In Captain Underpants and the Frantic Fury of the Fearsome Furculees, she goes with the other kids to rescue Krupp from the jungle. Unfortunately, Other Sophie manages to land miles away in another jungle with strange creatures called, Croco-Bats where they worship her as their queen until they bring her home five episodes later in Captain Underpants and the Bizarre Blitzkrieg of the Bothersome Butt-erflies. To fill in those five episodes, she is replaced with a tree sloth, which everyone stupidly thinks is her.
Like Sophie One, she has puffy hair with two mini curls at the end. Her hair is orange with a green hairband. Her glasses are purple with bright purple lens. She wears a dress the same color as her hairband and has a purple belt. Her sleeves are bright yellow/white and the vest underneath is white. Other Sophie wears white/yellow socks with green ballet shoes to match her dress. Her skin color is peach.
- Other Sophie doesn't seem to talk, but in crowds, she can be seen talking if the kids are bragging, or if she's yawning, or her and the kids are saying "Aw Man" for example even though her voice is not clearly heard in the crowds and sometimes she is shown gasping or screaming. Apparently, Jessica makes it a rule that Sophies aren't allowed to speak. However, Jessica might eventually change some rules letting Sophies have a chance of talking sometimes or she probably doesn't hear them in crowds.
- Other Sophie makes a goof appearance in Captain Underpants and the Preposterous Pulverizing of the Pestering Poopacabra instead of the sloth as her replacement even though she's supposed to be stuck in the jungle until Captain Underpants and the Bizarre Blitzkrieg of the Bothersome Butt-erflies.
- Other Sophie would also be known as Sophie Two.
- Other Sophie along with Jessica and Sophie One don't appear in Captain Underpants: The First Epic Movie.
- Other Sophie has a love interest in Bo.
- Other Sophie doesn't seem to smile very much, as she is seen a lot with a gloomy look. This is probably because Jessica mistreats her all the time.
- In the Hack-O-Ween special, her costume is a straight-jacked with an mask (similar to Hannibal from the Silence of the Lambs).
- She appears in all episodes, except for episodes 16 and 18 by being replaced by a tree sloth from episodes 15 to 20.
