Although, there was that one time her invention worked properly, but only the other multiples of 13 know about that...

Dodeca D.'s Thirty-Nine is unlucky triple Thirteen, which he splits into when he trips, gets hit or other bad things happen.

His face is on the bottom, but his blocks of tens are on top of his square face, which he feels that is “very unlucky”.

Dayton2949's Thirty-Nine is Twenty-Six's co-worker, meaning she can be great at finding hidden numbers just like him.

She’s also brothers with Sixty-One who is also another Specialised CS. Despite not being true squares, she and the other specialised CS’s can sneeze, but instead of sneezing out blocks, they end up shifting into a random wonky arrangement!

Dayton2949's Forty-One is a centered square, meaning that if you color her blocks like a checkerboard and turn her 45°, you can see that she is 16+25, two consecutive squares. Despite not being a true square, she and the other centered squares can sneeze, but instead of sneezing out blocks, they end up shifting into a random crazy arrangement!

CloudyWithAChanceOfRainbows's Forty-One is always trying to get some new members in prime club, using the Sieve of Eratosthenes. She always keeps six Prime Club badges on her to give out to new members, and when there's trouble, she can split into the prime patrol: 2, 3, 5, 7, 11, and 13!

DeltaMakesArt's Forty-One hates rectangles. They use their wand to zap rectangles and turn them into primes by removing their array displays. They don't actually know what a centered square is, despite being a centered square themselves, and are reluctant to rearrange into one after being told they're a centered square because "squares have factors and they don't want any factors around here".

Dodeca D.'s Forty-Seven prefers to be a wall flower and go unnoticed, which interferes with the Numberblocks’ friendships with her. She tends to try to hide her face whenever she blushes or feels uncomfortable. Clearly, she is shy, but once you break through her thick outer shell, she's very nice and a worthy character. Also, she has a fascination with anything that's made of silver, as she's the atomic number of silver. And she’s one less than mega rectangle Forty-Eight, can arrange into a chippy square (Which is two less than a square number) and is also a Leapfrog/Lucas Number.

TSRITW's 2nd design of Forty-Eight is a "multiplication master", and knows all the factorization terminology. He knows a secret to finding the number of rectangles a Numberblock can make, but that requires knowledge of a certain operation that they don't know yet...

TSRITW's design of Fifty-Three is an astronaut who thought of 53 more things to do in zero gravity. She's also interested in bears, for some reason.

ThatGuy30722's Fifty-Three introduces number bases—the idea of a different number other than Ten getting the “one big 10-block” privilege. For example if the number we call 16 got this privilege (this is known as base 16, or hexadecimal), then 53 would become 35—he’s three sixteens and five (as seen by his shape)!.

Dodeca D.'s Fifty-Three is a very curious prime number. What she is mainly curious about is about imagining if other Numberblocks had the “Big Ten Block” aspect. She introduces bases, in this case, she’s sixteen blocks high with five blocks left over. If each group of the sixteen blocks were instead interpreted into base-16, she would become 35 - three Sixteens and five Ones, which we would call it Thirxen-Five!

Fernandez7090's Fifty-Three introduces bases: The concept of another number taking Ten's role. In this case, if Sixteen takes Ten's role, then he becomes 53. The same digits but reversed.

CloudyWithAChanceOfRainbows's Fifty-Four is a super duper rectangle who likes folding and unfolding 3D shapes. Her "squares" can be removed and rearranged, but if the arrangement isn't a legit unfolding of a cube, she becomes an evil version of herself that wants to turn everything flat (like flatam from odd squad).

Dodeca D.'s Fifty-Four is not a cube but rather a cuboid. She takes 3 dimensions to a whole new level that she demonstrates that Numberblocks can be arranged in 3D shapes, like Eighteen being arranged as a rectangular prism.

Dodeca D.'s Fifty-Seven is triple Nineteen, but loves a particular shape more that most crazy shape - crosses! He can be a really big, thin cross, or a smaller, chunkier cross. He’s a semi prime, which means that he can only make four rectangles.

Sixty-Nine is a Numberblock made of 69 blocks.

Fanmade Designs

ThatGuy30722's Sixty-Nine loves anything with rotational symmetry (looks the same upside down), such as his pair of Numberlings. For some reason, whenever he says his name, other numbers end up laughing.

Dodeca D.'s Sixty-Nine is very special: see his pair of numberlings below? The 9 looks like a number 6 but turned upside down. That’s where he gets his purpose - he loves anything with rotational symmetry where something looks the same upside down if the symmetry is repeated correctly. He has four legs, but only two of them can work at a time. If he wants to get his other legs moving, he needs to flip himself upside down, thus causing the other pair of legs to stop working! He even has two mouths which function the same as the legs. He is also a comedian as he is triple 23, and also a nod to how 69 is considered a “funny number” by many.

Fernandez7090's Sixty-Nine loves rotational symmetry since his numberling is the same digit but with one of them upside-down. He is also a stand-up comedian who tells (very unfunny) jokes about math as 69 is called the "Funny Number" in pop culture.

ThatGuy30722's Seventy-One is prime, and when he stands 2, 3, 4, 5, 6, 7, 8, 9, or 10 blocks wide, he is exactly one more or one less than a rectangle! Being so close to so many rectangles has made him insane.

Fernandez0907's Seventy-One greatly dislikes rectangles, due to him being one-off when standing 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 blocks wide. He also loves keyboards as he is the number of characters that can be used in a keyboard.

CloudyWithAChanceOfRainbows's Seventy-Two is a hyper rectangle that loves 3-string Numberblocks (numberblocks that can become ones by only splitting in half or splitting in three), and usually hangs out with them. When something happens between Numberblocks that aren't 3-string, he usually remarks that it's "none of his business", which may come off as rude to some.
