Numberblocks Wiki

I’m agent Twenty-Six.

— Twenty-Six, Hidden Talents

Twenty-Six, or 26, is a Numberblock made of 26 blocks.


Twenty-Six has twenty orange-bordered apricot blocks and six indigo blocks, he has a black bowler hat, glasses, and a tie. He has pink lips, purple thick eyebrows, and dark red eyes. Notably, his arms are stylized that look like his six block is his "uniform" with "sleeves", with it ending in apricot, with white in-between.


Little is known about Twenty-Six's personality. Thus, all we know about Twenty-Six is that he is an agent good at finding "hidden numbers".

What is known, however, is that upon hearing his name, his glasses prop up before he splits into two Thirteens. (Conjectural: He has only done this a limited amount of times, and when he said his abstract name (flingty bun) in What If?, nothing happened.)

Episode Appearances


Agent Twenty-Six is usually seen as a 4x6 rectangle with a two on top. He can also make a bunch of other shapes out of all.

  • Contrary to popular belief, Twenty-Six's design is not based on language or the alphabet.
    • The reason of this was probably that Numberblocks is multi-language; other languages have more or less than 26 letters.
    • However, one can infer his personality is based off of variables, because according to Fifteen, he's good at finding hidden numbers, and variables are usually letters from the basic alphabet.
  • His glasses didn't prop up when he said "Flingty-Bun", which was temporarily his name during What If?. This might be an indicator that one has to say his real name for him to split in half.
  • He is the first Numberblock to get figured out without the help of Twenty-One (except for 21 herself). He got figured out with the help of Fifteen.
  • Twenty-Six is the first numberblock to have Nine's eyebrows besides Nine himself, the second being Sixty-Four, and the third being Ninety.
