I honestly don’t know why I chose the name “Kennedy” for Zodi Jr.  Darkevilhelldeath-Man has been referring to all of his underlings in a formal sense so far, so there was no avoiding it when it came time for him to address this most mysterious of supervillains.  The real Zodiac Killer has, of course, never been discovered (and all theories have been poopooed), so no logical name connection can be made in that department.  “Kennedy” just came out of thin air; although I guess it could be taken as a sick joke to name a gun nut after one of the most notorious sniper victims of all time.
