There will be very very very VERY few and less characters. Because the only digits in Binary are 1 and 0. We know that 0 is still 0 and 1 is still 1, but in binary, the characters are different. 10 (one-zero) is 2, 11 (one-one) is 3, and 100 (one-zero-zero) is 4. And they still have their own personalities and behaviors.
Since Binary is used for data, I make the intro, and background computery. I let Brenbot in the intro.
