This page is about the character(s). For the episode, see One Hundred (episode).

One Hundred, or 100, is a Numberblock made up of 100 blocks she is a square by 10×10. She is voiced by Sharon D. Clarke.


One Hundred has a chessboard pattern of 50 light red blocks and 50 dark red blocks. Her eye, mouth, and her limbs have the same color as One's. She also has an array display, because she is a super rectangle like 12,18 and 24.


One Hundred's personality is rather calm and gentle. She acts like a motherly figure to One (and Ten, to a lesser extent). She has been shown to help them understand very bigger numbers, even numbers bigger than her, and breaks the concepts down into steps they can understand.
