Multiply 9 by any positive integer and add the digits in the answer together (keep doing this again if you have two or more digits in this answer). You will eventually get 9.

1) 9 is the only square number (3^2) that is the sum of consecutive cubes: 9 = 1^3 + 2^3.
2) It is the smallest Kaprekar number because 9^2 = 81 and 8 + 1 = 9.
3) There are just 9 regular polyhedra.
4) 9 is the smallest number of distinct integral squares into which a rectangle may be divided. The smallest solution is 32 x 33 squares, where the squares have sides 1, 4, 7, 8, 9, 10, 14, 15 and 18.
5)The Feuerbach, or 9-point circle.
If you draw a triangle, then the 3 feet of the altitudes, the 3 midpoints of the sides, and the 3 midpoints of the segments of the altitudes from the vertices to their point of intersection, all lie on a circle.
6) 9 divides a number if and only if it divides the sum of the number's digits.
(this is not unique though, as it also applies to the number 3)
Hopefully, at least one of those must have the strange, anomalous characteristic to which you are alluding.

counting in base 8 (octal) the number 7 has the same characteristic.

It is exactly equal to 10 - 1. No other number has that claim!!!
