4

4 is a dark slate gray Number 4 with a tan underside. Her skin color is similar to L, but the latter is a lighter shade; her underside color is similar to Q. Depending on the angle, she has 6 horns. Two of them jut from her forehead and 4 from the side of her head, in addition to red scales on the back that closely resemble thorns, four red sharp teeth also likely jut from the mouth (two upper and two lower), two spikes on her tail which extends also when she extends like a vine, this makes her the appearance of a snake, specifically a viper. Four is the third character overall in the series not to have black pupils, following H and W, who have white and red pupils, respectively, and the third whose sclera are not white, after H (black) and 3 (yellow). Four is also the second character that doesn't have any pupils, the first being K, although K has shine in her eyes. Four has exactly four colors, being dark slate gray (main part), tan (underside), orange (eyes and tongue), and red (fangs and teeth). She is the second Number whose number is a perfect square. The first was 1, the third will be 9, and the last will be 0. (Mike confirmed that only single-digit Numbers will be in Number Lore.) She is the first Number: Whose number is semi-prime (a number that is the product of two primes). Whose second component Number (1) in the equation used to form her was less than the first component Number (3). Some people suspect that this is the reason why Four is female, since 2, 3 and 5, who are all male, had their second component Numbers in their respective equations either equal to or greater than their first component numbers. A popular guess from the community was that everyone thought Four was green. Then she was revealed to be a similar color, making most of their predictions the accurate color. Four is also the first overall character: That has orange eyes. Whose eyes are not shaped like the rounded squares. This is possibly because Mike said there will be an ability of hers that will come from her eyes at some point later in the series. Whose teeth are red. According to Mike and Galneda, Four is the first female Number in the series. This makes her the fifth overall female in the series, after K, P, W, and Y. That has visibly different-colored ventrals. Four's chlorokinetic ability is a pun on the square root of 4 being an integer, and her Roman numerals are “IV”, which is a pun on the ivy leaf. Four is the second serpentine character in the series, after S, in addition to the second character capable of burrowing, after T. She is the first plant character but comes after a long line of animal characters. People didn't expect that 4 would look like it's a little front-facing because in 4's silhouette, there's a tiny gap near the fang visible in the silhouette. 4's two spikes on her back and horns are things to illustrate Four as a number 4. Her design is very similar to the Dragon Zombie enemies from the game Cave Story. It is unknown if this is intentional or not. She and Y have alto (deep-pitched female) voices, while Mike has proven he can do a girly voice if P and the W sisters are any indication. Her name is said British, with the r being silent, being “fvoohhh” instead of “vfouerrr” However, there is a slight "twang" before she grows vines, making her voice sound Bostonian. Inspirations: Her fangs and tail are likely inspired by thorns. Her tail is likely based on Snowball II's tail from The Simpsons. Her two from the side of her head are likely inspired by Felix the Cat. Her skin and belly colors are likely inspired by Snorlax from Pokémon. Her head is likely inspired by Haunter from Pokémon.
