Which character was created by Frank Thomas besides Captain Hook from Peter Pan?

The character created by Frank Thomas, aside from Captain Hook in "Peter Pan," is indeed the Queen of Hearts from "Alice in Wonderland." Frank Thomas was one of the original nine animators at Disney and contributed significantly to the animation style and character development during the studio’s golden age.

The Queen of Hearts is a pivotal character in "Alice in Wonderland," characterized by her domineering personality and iconic catchphrase, "Off with their heads!" Thomas's work helped establish her as a memorable figure in animation history, demonstrating his talent in creating strong, dynamic characters.

On the other hand, the other options like Winnie the Pooh and Bambi were created by different animators and are associated with different films not directly linked to Frank Thomas's contributions. Winnie the Pooh, for instance, is more closely associated with animators like Frank Wells and Eric Larson, while Bambi was primarily the creation of other Disney artists. This distinction underscores the specific contributions Frank Thomas made to Disney's rich character gallery.
