A list of alter-egos in the Learningblocks series.
Alphablocks[]
Magic E[]
Magic E is is the alter-ego of E wearing a top hat and black ninja clothes. Unlike Silent E, he can actually talk. His magic hat "can make a vowel make a different sound" without even touching them, particularly, make the Alphablocks "say their name". An example is: Line.
Silent E[]
Silent E is an alter-ego of E, that may or may not be Magic E’s beta, as he hasn't been seen since Zzzzz.
Plusman[]
Plusman only appears in the episode of the same name. He is the alter-ego of X, being red and orange instead of blue and yellow. Also, his letter has a plus sign instead of an X. He can put two words together to make a compound word. The character is notable because he is a symbol, not a letter.
Numberblocks[]
Square Root Squads:[]
The One One[]
The One One first appeared in Square Club. The One One helped Square Club by clearing it of balls. Although you can technically say she’s in every episode with One, because she’s just a normal One. Not with a square eye, that’s a different form of One.
Representation: 1¹ or 1²
She was mentioned in Peekaboo! when One said “and I’m only one One,” although it was likely unintentional.

The Terrible Twos[]
These are two mischievous Twos who are divided from Four, and appear in the episode with the same name. Their mask colours are blue and purple. They love to tickle Numberblocks, who laugh (or possibly sneeze if it were a 9) and then get scared by the Twos. They get so scared they split into Ones. They often appear when Four struggles to make a decision where he "can't do both", although in later episodes they are independent from Four.
Representation: 2²
They make mischief in other ways as well, such as in Square Club when they pulled a rope and dropped a bunch of balls onto the floor, intentionally breaking the club's "no round things" rule. In later episodes, the two have seemingly become more drastic in the mayhem they make, going as far as to forcefully divide Numberblocks, and gaining the ability to become Octonaughty.
They're the only square root squad who is not named "The (X) (X)s".

The Two Twos (debatable)[]
There have been times when Four would split, and they were not Terrible Twos. Recently, the Terrible Twos seem to have been dissociated from Four, not really having anything to do with him.
The Three Threes[]
These are three Threes who are divided from Nine, and debut in the episode of the same name. They have three different moustaches of different thicknesses and are acrobats. One time they help One open a jar of honey by individually performing stunts. In Square Club, they also kept up the performer theme by juggling the balls that the Terrible Twos dropped. This didn't really help the situation, however. They also made cameos in Mirror, Mirror (does not show moustaches), Divide and Drive, and Crossover (all had the same moustache).
Representation: 3²
The Four Fours[]
The Four Fours are a result of Sixteen splitting in half into two Eights then into the Four Fours. They all have the same barbershop hat with a green ribbon wrapped around it and sing as a barbershop quartet. They appeared in Square Club and, due to having the same fear of round things as other Fours, couldn't help the situation the Terrible Twos caused. They later appeared in other episodes, including Divide and Drive, Four on the Floor, As Tall as the Sun, Friendly Fours' Beach Day, and Super Eights Assemble.
Representation: 4²
The Five Fives[]
These are five Fives who are divided from Twenty-Five. They appear in Five and Friends, Hidden Talents and All-Star Line-Up. They have also been seen previously in We're Going on a Square Hunt as a drawing.

Representation: 6²

Not-So-Secret Secret Identities[]
Octoblock[]
Octoblock is the superhero name for Eight. There is a not-so-secret story that states he got his powers from being tickled by a radioactive octopus. His catchphrase is "Octoblock, (command)! 1, 2, 3, 4, 5, 6, 7, 8, (said command)!" He is almost always in this form, with an exception being in a part of Octoblock to the Rescue! and in some glitches, examples include (but not limited to), Nine and Fun Times One Times Table. See below his villain form, Octonaughty.
Instant Octoblock[]
Instant Octoblock is formed when eight ones add together when Seventy-Two’s eight Nines sneeze. He only appears in Seventy-Two's Super Surprise and Nine's Time to Shine.
Octonaughty[]
Octonaughty is an Eight who plays an antagonistic role in all the episodes he appears in.
Octonaughty is the result of the Terrible Twos duplicating themselves and then combining. He is Octoblock's villain counterpart, proven that he does the absolute reverse of everything Octoblock does, such as his catchphrase being "Octonaughty, (command)! 8, 7, 6, 5, 4, 3, 2, 1, (said command)!". Octonaughty's voice is also more high-pitched and goofier than Octoblock's. Instead of counting forwards from 1 to 8, he counts backwards from 8 to 1
He first appears in Season 3's Octoblock to the Rescue!, not reappearing again until Ten's Top Ten, and then Now in 3D. He is somewhat more crazy in Now in 3D, as shown when he flails his tentacles and laughs after disassembling Twenty-Seven. He's also shown to be somewhat incompetent, making the Dimension-ator to become a powerful cube despite it being redundant, at least until it got broken. He was the main villain in the episode Crossover, where he stole the magic home mirror to trap all the superheroes in Numberland and allow himself to cause mischief uninterrupted in Alphaland. He was once again stopped by Twenty-Seven in the episode due to being unable to swap her with a letter of the alphabet, because there are only twenty-six letters.
Step Squads[]
Step Squads who are divided from the triangular Numberblocks. The first to appear is Fifteen. Fifteen can be divided into One, Two, Three, Four and Five. (Which are all the characters from Season 1)
- 15: 1+2+3+4+5
Then Fifteen tells the other triangular Numberblocks (1, 3, 6 and 10) that they can also be Step Squads.
- 1: 1
- 3: 1+2
- 6: 1+2+3
- 10: 1+2+3+4
The Step Squads can help other Numberblocks or other things and animals from accident.
All numbers of the form (where n is an integer) are step squads. (The first few are 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66...)
- 15, 21, 28, 36, 45 and 55 are the Numberblocks who appeared in the show which have a permanent step mask. The smaller steps 1, 3, 6, 10 don't have one, as well as Three Hundred (300 is the 24th step), oddly enough.
The step squads from 1 to 10 only appear in the episode Step Squads, and step squad 10 one more time in One Giant Step Squad.
Other[]
Two Tens Tango[]
The Two Tens Tango are divided from Twenty. They appear in Twenty.

The Terrible Twenties[]
The Terrible Twenties are Forty's version of The Terrible Twos. They only appeared in Land of the Giants when Forty didn't know which way to go after Oblongy. They seem to be identical to the Terrible Twos in character.

Super Octoblock[]
This is Eighty's alter-ego. His catchphrase is "Octoblocks assemble (splits into 10 Eights, reassembles, combines to make Eighty again)! (Transformed creature, command)!"
Representation: 10 × 8
So far, he has three different transformations, called Roboctoblock (a robot), Dinoctoblock (a dinosaur) and Spidoctoblock (a spider). Out of these, Dinoctoblock appears the most, and Spidoctoblock the least.
Double Eleven Football Teams[]
The Double Eleven Football Teams are special forms of Eleven when Twenty-Two splits in half, as seen in Twenty-One and On and How Rectangly. One of them is red while the other is blue, representing the red team and blue team in football, and after that they can both split into eleven ones, who are also coloured red and blue, respectively.
Representation: 2 × 11
Double Thirteen[]
Double Thirteen are Twenty-Six’s alter egos. While they really are used to find hidden numbers in a Numberblock, they are more or less are like Thirteen in terms of personality, as shown in Club Picnic.
Representation: 2 × 13
Super Cubes[]
Super Cubes are basically just cubes that use their power of three dimensions to save the day. They consist of 8, 27, and 64.
The Super Cubes were first introduced in Now in 3D when Twenty-Seven helped Eight release from Octonaughty's trap.
Sixty-Four also introduced herself as a super cube in Square on the Moon.
