“ Octoblock 1, 2, 3, 4, 5, 6, 7, 8! ”
 

— Eight, his debut

Eight, or 8, (commonly referred to as Octoblock) is a character who appeared in Numberblocks. He is well known for his alter-egos, Octoblock and Octonaughty. Eight first appears in the episode of the same name. He is voiced by Marcel McCalla.

Appearance

Eight is made up of 8 bright magenta/hot pink blocks, with 8 octopus-like limbs of which he uses six for arms and two for legs (mostly used in a 2x4 arrangement). He wears a dark purple infinity symbol-shaped mask with 8 spikes, 4 on each side.

Starting from Series 3, Eight's superhero mask and mouth are lighter.

Starting at Now in 3D, whenever Eight transforms into a cube, he gains a bright magenta/hot pink cube symbol above his eyes.

Personality

As the superhero Octoblock, Eight is brave and heroic, narrowing down to helping others in need with numerous different abilities that he can use at his disposal for different situations, as well as being very reliable in thwarting the schemes of his enemy, Octonaughty.

He is also very friendly, and can be touchy when he is, such as in Eleven, when he side hugs Nine, and when he catches Six as she was about to fall in One Giant Step Squad.

Octoblock's helpfulness is showcased in Fluffies, where he helps get rid of the Fluffies that are latched onto the four Sevens, in Building Blocks where he helps build the tower to get an alien to their home planet, and in episodes like Nine, Blast Off, Numberblock Castle, Peekaboo! and Flatland (although it wasn't really him, it was Octagon) where he is proud to help the others get to places that they couldn't without him.

He is also shown to be rather skilled in sports, as shown in The Two Tree, where he manages to throw the Two through another Eight's hole with ease.

Despite being a superhero, and an octopus themed one at that, he isn't very bright, as seen in his debut where he somehow doesn’t know what octopuses do, in Puzzle Square where he tries pushing the door right after the Six Sixes told him how to open it, and especially in Octoblock and the Path of Justice where he has trouble reading maps.

As of the Alphablocks and Numberblocks crossover special: Crossover, he and X are friends.

LearningBlocks.tv website's description

Numberblock Eight is known by his superhero name: Octoblock. He’s got eight arms (or are they legs?) and when he needs to run fast, swim a long way, climb up high, knit in a hurry or more he changes shape to activate a unique special power each time: Octoblock Run! 1-2-3-4-5-6-7-8 Run!

Episode Appearances

Total number of appearances: 97 + 1 (including pictures)

He has appeared in 62.03% of Numberblocks episodes, including the crossover specials.

Octonaughty

Octonaughty is Eight's supervillain alter-ego and enemy. He is a recurring antagonist in the series. He has a high-pitched, goofy voice and evil personality. Other than Eight, he has a particular dislike for Twenty-Seven and Seventy-Two.

Appearance

He is the same as Octoblock, but with green tentacles and a green mask. He has small pupils and big teeth. Whenever he's in a cube-shaped arrangement, he has a green cube symbol above his eyes.

Octonaughty is the result of the Terrible Twos duplicating themselves and then combining.

He is Octoblock's arch-enemy and villain counterpart, proven by his high-pitched, goofy voice, and everything he does is the reverse of what Octoblock does, as his catchphrase is "Octonaughty, (command)! 8, 7, 6, 5, 4, 3, 2, 1, (said command)!" (however, this only happened in 1 episode). Unlike Octoblock who is brave, heroic and helpful, Octonaughty is very selfish, always coming up with schemes to defeat Octoblock that always fail. He is also rather cowardly, shown when he escapes every time his plans fail.

The first time Octonaughty appears is in Octoblock to the Rescue!. Although he doesn't really have a villainous scheme in the episode, he does still provoke Octoblock enough for four more Octoblocks to appear and overpower him, leading him to escape in a last-ditch effort to get away, though he does get his comeuppance after falling into the giant custard pie as the other Numberblocks laugh at his defeat. He makes a brief appearance in Eight's scene in Ten's Top Ten, where he has Five and Three locked in a cage, but is soon defeated by two Fours.

In Now in 3D, Octonaughty appears to be crazier than before with a new villain laugh and a new scheme, the Dimension-ator, which is used to turn Octonaughty into a cube, which allows him to run amok around Numberland turning all Numberblocks into jumbled up 3D shapes, including Octoblock who he has captured and put into the Dimension-ator. Later in the episode, Twenty-Seven manages to free Octoblock and put a stop to Octonaughty.

In Crossover, Octonaughty has become outright evil, now plotting to take over Alphaland even though the Alphablocks didn't do anything to him. He does this by manipulating the Magic Home Mirror's powers with a device to rid X from Alphaland so that no superheroes can stop him. Because of Octonaughty's scheme, Twenty and Twenty-Four became stranded in Alphaland while T and X were stranded in Numberland. However Octonaughty's plan failed yet again as Twenty-Seven exploited Octonaughty's device and caused him to flee though a glitched Magic Home Mirror. Unless Octonaughty was simply able to “replace” the narrator at the end, it reveals he can perfectly disguise his voice.

In Octoblock and the Path of Justice, he jams the signal to the Octo-Computer to prevent Octoblock from stopping his naughty prank of making a big splash over Triangle Lake via a giant rubber duck, enlarged by a resizer ray. Once Eight has gained confidence in reading maps, he proceeds to take a shortcut to an alley to meet Octonaughty at Triangle Lake, with the resizer ray in Octoblock's hand. Octonaughty then gets shrunk back due to forgetting the resizer ray and is jarred up to which Octoblock replies, "For now, I like knowing exactly where you are".

Trivia

  • Eight is very obviously inspired by Spider-Man. In his debut, Two accidentally called Eight 'Spiderblock', as he crawls like a 'creepy rectangular spider'. As seen in Now We Are Six to Ten, he has a backstory that closely parodies Spider-Man's backstory.
    • In Octoblock to the Rescue!, his Octo-Signal is a parody of Batman's Bat-Signal, and Octonite is a parody of Superman's kryptonite.
      • Octonaughty can generate signals too, but only did that in Now in 3D. So can X, as revealed in Crossover.
  • He is the second Learningblock to be a superhero, the first is X.
  • He is the second Numberblock who doesn't sing in his debut, the first being Six (she raps instead).
  • It is possible that Eight's mask is part of his real eyes. This is supported by the fact that he still had them as a civilian, but contradicted by his official profile referring to it as his “superhero mask.”
  • Eight is the only Numberblock greater than 5 who made more than 3 arrangements in the first series.
  • Eight had a continuous error where he had 4 normal limbs, especially whenever Nine sneezes. The episodes Eight had the error are below.
  • Eight is currently the only cube number to be male.
  • He has a close relationship towards Six.
  • Eight has made the most 3D shapes out of all the primary Numberblocks so far.
  • Starting from Series 3, Eight has a lighter-coloured mask and slightly smaller eyes. However, his old appearance is still seen in the intro and even on his player card during The Team Factor. His facial proportions also got more consistent since Series 3.
  • According to Now We Are Six to Ten, Eight wasn't Octoblock until he got tickled by a radioactive octopus, although this is contradicted by the fact that he was already Octoblock in his debut episode.
  • Eight is the first Numberblock to make diagonal shapes (his "bend" form (zigzag) and his "pop" form (which is just the donut, or square-with-hole, but diagonal).
  • Eight has the deepest voice out of all of the primary Numberblocks.
  • Eight is the second cube Numberblock to be figured out.
  • Eight is the only Numberblock to have ever disconnected his blocks, while still maintaining his number.
  • He is the only Numberblock with a mask to not be a super rectangle.
  • He is the only Numberblock with eight limbs to not be a super rectangle.
  • He, Four, and Sixteen are the only Friendly Fours that are not super rectangles.
    • This is because Four does not have enough prime factors while Eight and Sixteen repeat prime factors (which causes you to make less factors). He’s the only Numberblock in the Four Times Table to have round eyes, since he doesn’t fit in the category of being a square or being a Super Rectangle, as he is a cube, and currently the only cube in the Four Times Table.
  • In Series 2, he is the biggest even single digit Numberblock, and the biggest cube Numberblock to be figured out.
  • Out of all the Orange Level Two characters, Eight has never been the smallest in any episode, if the episodes where he appears alone aren’t counted.
  • He is the smallest Numberblock to have a mask, followed by Fifteen, Twenty-One, Twenty-Seven, Twenty-Eight, Thirty-Six, Forty-Five, Fifty-Five, Fifty-Six, Seventy-Two, and Eighty.
    • If temporary masks are counted, this is not the case, as One, Three and Six temporarily had masks.
    • Eight, Twenty-Seven, Fifty-Six, Seventy-Two, and Eighty are the only ones in this case to not have a Step-Squad mask.
  • It is possibly unknown if Octonaughty's 10th multiple, Super Octonaughty, will be in the show.
