Twelve, or 12, is a Numberblock made of 12 blocks.

She is voiced by Emma Tate.


12 has 10 white blocks and 2 orange blocks. She has also thin eyebrows, rectangular eyes, red limbs like 10, and has a pink thing on her wrist called her "array display" on her left hand, which looks like a rectangular watch. She is often arranged in a rectangle, which is her favorite shape.

When 12 is in her 3-by-4 or 4-by-3 form, her 2 orange blocks are in the middle and 10 white blocks at the outside (a tall donut or a rectangle with a hole, 2 has said the second one on 12‘s debut episode). She first appears in her 3-by-4 form.

When 12 is in her 2-by-6 or 1-by-12 form, her 2 orange blocks are on the 10 white blocks.

When 12 is in her 6-by-2 or 12-by-1 form, her 2 orange blocks are next to the 10 white blocks. In her 6-by-2 form, her 2 orange blocks can be either on the left or right of the 10 white blocks, but in her 12-by-1 form, they can just be on the right.

  • 12 was heavily despised by BattleReviews and MrYokaiAndWatch902 (probably others too), because she was nothing related to Time/The Start of Winter/Christmas. Battle even went far to say 12 was "based off of laziness", and like said, 12 was nothing related to the above.
