Bill Buck is the creator of Ace Savvy, but not much else is known about him so far.
He is an elderly man, with gray hair behind his head, (he has no hair on top of his head) and he wears small, round glasses, and has eyebrows that are the same color as his hair. He wears a yellow collared shirt, a black leather belt, red suspenders, brown slacks, green socks, and brown shoes.
It's also a combination of the words "bill" and "buck", both of which refer to money.
In Campaign Chaos!, it is mentioned that he has written a non-fiction book about writing comics, titled Comic Writing Guide for Comic Lovers Who Love Comics. The Royal Woods Library has a copy of, but Lincoln always has trouble getting to check it out.
