Ten, or 10, is a Numberblock that is made up of 10 blocks. She debuts in the episode with the same name. She can turn herself into a rocket and fly into space. She is voiced by Teresa Gallagher.


10 is made of ten white blocks with a red border. She has star-shaped red eyes and pink lips. She has dark red limbs and wears two white gloves in her hands. Sometimes her 1-block outlines disappear, which makes her a 10-block. (This also occurs to Eleven, Twelve and Thirteen in the episode On Your Head.)
