Thirteen, or 13 (also known as Ten and Three to prevent the Numberblocks from saying his name) is a Numberblock made up of 13 blocks. He is voiced by Marcel McCalla.

He is a clumsy and unlucky Numberblock who is very prone to accidents and trouble. Every time someone says his name, he splits into Ten and Three.

Appearance

Thirteen has 10 white blocks with a red border and 3 yellow blocks. His usual block arrangement contains his 2x5 ten block with his three yellow blocks dangling on top. However, his block arrangement change in almost every episode so it's unclear on what his actual arrangement is. He additionally has mulberry-purple eyes and eyebrows, and mouth. Additionally, he has limbs with the same colour, only with a gradient to a darker purple.

Featured in his debut, Thirteen occasionally wears a boater hat. The ribbon matches the scheme of his block colours. He additionally wears a spotted bowtie in Fifteen's Minute of Fame, similarly resembling his block colours.

Personality and Traits

As a reference to the superstition, Thirteen is an incredibly unlucky Numberblock, commonly falling into accidents and splitting into Ten and Three upon hearing his name (or hearing it through the fourth wall), with an exception in the episode Subtraction Somersaults. Despite his accident-prone nature, Thirteen attempts to make light of his situation, commonly resorting to humour and turning his unfortunate problems into comedic, playful situations. He appears joyful and friendly, often admiring the talents of others and playfully joking around with his friends. Thirteen is also very sweet-natured, never responding with anger to mistreatment and instead focusing on helping others.

Despite typically laughing his unluckiness off, Thirteen is shown to be heavily impacted by the actions of others, often expressing sadness and disappointment when he is subjected to anger and frustration. He is also shown to be more anxious and fearful in more serious and problematic situations, often straying to the side rather than actively participating. Notably, he still also expresses stress and sadness when others say his name unnecessarily and is frequently shown worrying about his unluckiness.

Numberblock Thirteen is rather unlucky. His catchphrase is Unlucky Me! Whenever anyone says his name his Three falls off! He tries to say "Ten and Three" rather than "Thirteen" but even he forgets sometimes.

Character

He is the fourth Numberblock to be voiced by Marcel McCalla, and the first male odd number to be voiced by him.
He is the sixth prime number.
He is the second Numberblock numerically that doesn't appear in Series 6 nor Series 7, the first is Zero.
He is the third male Numberblock who is an odd number, the first two are Seven and Nine.
As shown in his debut episode, Thirteen does not split when he sees his name written down, even though he still splits upon hearing his name spoken verbally.
The splitting of Thirteen can be prevented by immediately adding or removing a block, as seen in Eighteen and I Can Count to Twenty. It can also be prevented by physically pushing the Three back onto him, as seen in On Your Head, where Fourteen prevents Thirteen from splitting. This was also seen in Ten's Place where Three also pushed Thirteen's blocks together when she added One and Twelve.
He is the only Numberblock from 11-20 to not have one of his arrangements be "Ten and (x)" during his debut episode. 12 and 16 don't start out in their "Ten and (x)" arrangement at first, but rearrange to such position.
In "Flights of Fancy", 13's planet is one filled with echoey caves that allow his name to repeat. This implies that 13 likes his trait where he splits into 10 and 3 when he hears his own name, at least in a controlled environment.
In his debut episode, at first, he is only shown splitting into Ten and Three manually after saying his name, however, as the episode progresses, he starts to automatically split, and his splits stay automatic from then on.
He is the first prime Numberblock to have eyebrows.
He is one of the few Numberblocks to be the opposite gender of both their digits, alongside 24, 27, 28, 31, 35, 36, 48, 49, 55, 63 and 72.
He has the same mouth model as Nine.
Not counting Zero, he is the first Numberblock numerically to appear in less than 20% of the show.
Thirteen is the third prime Numberblock to have purple limbs.
He is the first Numberblock to be introduced after a super rectangle.
As of Series 8, all Numberblocks who are multiples of thirteen have eyebrows.
He is similar to Twenty-Three in five ways:
- He is the first three ender to be male, the second being Twenty-Three.
- Both are also voiced by Marcel McCalla.
- They both have three one blocks.
- They both have not debuted in Series 6 nor Series 7.
- They are both prime numbers.
He is the second prime (and the third odd) whose main arrangement is not their tallest.
He’s the first double-digit Numberblock to be male.
