She is voiced by [[Emma Tate]].

== Appearance ==
Twenty-One has 20 apricot blocks with an orange border and one red block. She has red limbs, pink lips, wears an indigo step mask because she is the 6th step squad, and two socks and boots, both apricot and red. She also wears a camping luggage and a green Tyrolean hat with three rainbow coloured "feathers", because she is 3x7, and can be seen holding a walking stick. 

== Personality ==
Twenty-One is friendly, curious, and adventurous. Twenty-One loves to explore numbers and is great at helping new Numberblocks figure themselves out.

As shown in [[Twenty-One and On]], she cannot discover who [[Twenty-Three]] is, as they refuse to shift any blocks, saying, "I am happy being me ([[Twenty]] and [[Three]])!". She gets disappointed and says that she wants to explore more now instead of letting Twenty-Three be a [[Compound Numberblocks|compound]]. Twenty takes off the Three and says, "Well, I've got a bus back there!".

==Captain Hexbeard==
{{Disclaimer|Captain Hexbeard is <big>MALE.</big> Whether this proves/disproves anything about Twenty-One's ordinary gender identity is <big>UNKNOWN</big> until writers for the Learningblocks shows confirm otherwise.

"He" turns out to be Twenty-One, but it’s unknown if he's a real character (that Twenty-One disguises as) or just made up by Twenty-One.

==Trivia ==

===Compound (Twenty and One)===
*21 was the first Numberblock to have more than two eyes and one mouth.
**She was also the first Numberblock to have two faces.
**She was also the first compound made up of two genders.
*The fact that the 21 in [[I Can Count to Twenty|''I Can Count to Twenty'']] is just 20 and 1 conjoined reflects how the Alphablocks form digraphs and trigraphs in their [[Alphablocks (show)|show]] (For example: [[Q]] conjoins herself with [[U]] to form the digraph "qu"; [[H]], with [[C]], [[S]], and [[T]], form "ch", "sh", and "th" respectively; [[I]], [[G]], and [[H]] form the trigraph "igh"; two [[O]]'s conjoin with each other to form "oo", etc.).
[[File:Non-answer.jpg|thumb|Except she asked if there was ever a real one.]]

===Figured-Out (Twenty-One's own character)===
*Twenty-One is the first Numberblock to exceed {{C|Twenty}}.
*She is the first Numberblock to figure herself out, and without anyone's help.
*She is the second character to have a permanent step mask. The first such character was [[Fifteen (character)|Fifteen]].
*She is the 6th triangluar number (step squad).
**One, Three, Six and Ten had step masks in [[Step Squads|''Step Squads'']]; but the masks weren't permanent.
*It's possible that Twenty-One had an early design concept before her final one. Her appearance as sketched in the storyboard of [[We're Going on a Square Hunt|''We're Going On A Square Hunt'']] (viewable in [https://youtu.be/DpXkS3ng7OY?t=132 this compilation]) looks quite different. In it, she has no hat or backpack; her face is on the bottom of her blocks; and her hair resembles [[Seven (character)|Seven]]'s.
**It's also possible that the storyboard was made before the episode [[Twenty-One and On]].
*She is the first multiple of [[Seven (character)|7]] to be female.
*She is the first Learningblock to be an explorer, the second being [[Brown (character)|Brown]].
*Her step-mask is navy and not indigo for unknown reasons.
*Her boots are slightly different from [[Fifteen]]'s, [[Twenty-Eight]]'s, and [[Thirty-Six]]'s boots, as they resemble hiking boots.
*Twenty-One was the first compound Numberblock figured-out.
*Her story board design has hair, but when she takes off her hat in [[The Treasure of Hexagon Island]] she is bald.
*She is the smallest Numberblock to not have a vertical arrangement.
*A fan asked if Captain Hexbeard was a real person in-universe, or if 21 made him up. A straight answer was never provided.
*She speaks in a Scottish accent.
*Going by release date order, she and [[Twenty-Two]] are the last Numberblocks to be in order of figuration. 25 and 30-100 break this pattern.
**However, in the order of the [[Levelling System]], [[Forty|40]] broke the pattern.
*Twenty-One is the fourth Numberblock whose main arrangement is the same as her factorization, after One, Four, Nine, Sixteen, and before Twenty-Five.
**She is the only non-square to have this happen.
