— Twelve, various episodes |
Twelve, or 12, is a Numberblock made of 12 blocks. She is voiced by Emma Tate.
Appearance
Twelve is made of 10 white blocks with a red border and 2 orange blocks. Her usual block arrangement is a 3x4 rectangle with two orange blocks in the middle, and the ten block surrounding it. She has thin, burgundy eyebrows, rectangle eyes, pink lips, and red legs with red shorts. Her left arm features a rectangular white and orange watch referred to as an "array display". Twelve is able to project holograms of various rectangular arrangements or "arrays" using its screen.
Personality
Twelve is a composed super-rectangle often seen practicing her yoga abilities. She holds her title with pride and confidence, often announcing her status as a super-rectangle to others, being naturally extroverted and extravagant with introductions. Despite on this, Twelve is very supportive of her friends, often quick to indirectly guide others into finding a solution to their problems, rather than directly interfering and giving answers herself. Holding more calm and rational thoughts than others, Twelve commonly leads and advises other Numberblocks, frequently looking out for their well-being. Her support and patience, however, occasionally grows weary, sometimes expressing concern and confusion to those more energetic and impulsive.
Despite her serenity and leadership mindset, she is also shown to encourage more rowdy situations herself, even participating gleefully with others. Twelve is also displayed to have a sense of heroism, willingly rushing through risky situations to assist others.
Aside from practicing her unique abilities, Twelve also frequently meditates and practices yoga. She tends to gravitate naturally towards organizing objects in columns and rows.
She can control clocks using her hands and her mind, as shown in About Time.
