— Forty-Two, various episodes |
Forty-Two, or 42, is a Numberblock made of 42 blocks.
Appearance
Forty-Two has 40 light green blocks with green borders and 2 orange blocks. He has blue rectangle eyes with thick blue eyebrows, and a blue mouth with teeth similar to Four or Forty. He has a rainbow teleportation belt with an indigo hexagon buckle that has 6 dice spots. He has blue limbs, and an array display as he has 8 factors.
In More to Explore, he only appeared as a drawing. He has no eyebrows, and he has a maroon robe with checkers where the blocks go, meant to resemble Arthur Dent from Hitchhiker's Guide to the Galaxy (the franchise that popularised 42 as being "the answer to life, the universe, and everything"). It's unknown if he is wearing the belt underneath the robe. He has dark blue shorts as well, which are absent in the final design. He is shown carrying a cup of tea and a towel. Everything else is the same otherwise.
Personality
Forty-Two’s notable gimmick is that he has a teleporting belt with a hexagon buckle that always gets out of hand. Whenever it glows, rainbow portals appear, making him teleport from another place to another, often making him disoriented.
He is shown to be dependent, often saying “Don’t panic!”, meaning he is reliable on others and minds others’ problems.
In Rescue Racers, he is shown to be sensible when he says “don’t panic” for when he’s teleporting, He is also thankful when he thanks Forty-Eight for rescuing the six Sevens.
In The Rainbow Makers, Forty-Two is also shown to be helpful, giving Sixty-Three advice when he’s feeling down, saying “Just be yourself!”.

Arrangements
Trivia
- Forty-Two’s non-physical drawing in More to Explore is most likely based on Arthur Dent from "A Hitchhiker's Guide to the Galaxy", hence the reference "42 is the meaning of life" and David Carling's post.
- Forty-Two's catchphrase, "Don't panic", is also most likely a reference to the series.
- In his drawing, despite being a multiple of 7, he doesn't have any rainbow features. However, after being figured out, he wears a rainbow belt.
- His drawing was likely teasing how he would look in future appearances. Just like how other Numberblocks first appeared as semi-official drawings, he also ended up closely resembling his, showing only a few changes.
- Forty-Two is chronologically the second Numberblock introduced in Series 7, since 48 debuted a bit before him.
- Numerically, he is the first new Numberblock in Series 7.
- His face looks very similar to Forty's, only with blue facial features instead.
- His digits are the reverse of Twenty-Four's digits. Coincidentally, they both have blue eyes and limbs, eight factors and both numbers are multiples of 6.
- He is currently the only Numberblock in the 40s to be male, aside from Forty himself.
- Before the release of Rescue Racers, David Carling announced he would be voice acting in Numberblocks, publicly saying "A couple of fun characters , one is the meaning of life 😉…".
- He is the second super rectangle whose main arrangement isn't rectangular. The first is Twenty-Eight, the third is Forty-Five and the fourth is Fifty-Six.
- Coincidentally, his main arrangement is the same arrangement featured in his drawing.
- He is the eighth Numberblock to be the same gender as both their digits after 10, 11, 15, 16, 22, 29, and 30.
- He is currently the only figured-out Numberblock that has never been shown in their "X tens and Y" arrangement anywhere.
- His 40 blocks are a bit lighter than 40’s, like 48’s.
- Forty-Two is the last figured-out Numberblock in the Forties to be physically shown, but if his prototype design is counted, then Forty-Eight would be the last one.
