J

from Fancyclopedia 2

The furriners have from the beginning used this for the sound we designate with Y, Englishers generally take it to indicate the compound (dz) sound. However that may be, we have it, and it vies with D for initialling the greatest number of fans. J, The J, and Forry the J are all ekenames of Forrest J Ackerman, tho he found out one day that J isn't his legal middle initial.
