Adding letters/number to answers as chosen by Random Number Generator. Letter (*) and number (#) patterns below. If there is a forward slash, the first name is the code name and the second name is the real name (for such characters I'll accept either name).  Not every number appears in this collage but every letter does. Obviously if a letter is revealed but not shown for a particular character, they don't have that letter in their name.

Adding the number 3 and the letter R.
