— Eighty, his debut |
Eighty, or 80, is a Numberblock made up of 80 blocks. He is voiced by Marcel McCalla.
Appearance[]
Eighty has 80 pink blocks with magenta borders. His eyes, mouth and his limbs has the same colour as Eight's, the only difference is that he has a magenta octagon-shaped badge with purple borders and the number 80 on it, a cape, and an array display, as he has 10 factors.
Abilities[]
Eighty is able to shapeshift into a specific shape. He starts by splitting into ten Eights and then one of them say "Octoblocks, assemble!" before combining into Eighty but with a new shape. His forms so far are Dinoctoblock, Roboctoblock and Spidoctoblock (see below).

Trivia[]
- In some scenes, Eighty doesn't have his badge and/or cape. They are usually not included when he shape-shifts to any form other than his main 8x10 form (for instance his forms Roboctoblock, Dinoctoblock, and Spidoctoblock).
- There is a recurring error in which Eighty has four limbs instead of eight, Eight himself experiencing the same error. This error occured in Sixty's High Score and Nine's Time to Shine.
- Eighty has shape-shifted into his form Dinoctoblock the most, doing so in five episodes. Second to this is Robloctoblock in three episodes, and finally, Spidoctoblock in two episodes.
- He is the only physical multiple of 16 to be male.
- In Heroes with Zeroes, there is no sequence when Eighty shapeshifts.
- He is the sixth smallest Numberblock greater than Thirty to have circular eyes, after Sixty, Fifty-Five, Fifty, Thirty-Five, and Thirty-One.
- If the Orders of Magnitude and Two-Hundred and Three-Hundred do not count, as they've never been physically shown in an episode, then Eighty is the biggest Numberblock greater than Thirty to have circular eyes.
- His ten-borders were wrong once in the Series 7 episode Super Eights Assemble, the borders being around his ten eights.
- Every Numberblock in the Eighties including Eighty speak in an elder accent.
