Gene created Star Trek, then, brought Star Trek: The Next Generation to syndicated TV screens in the 1980s.
Star Trek #26 (December, 1991) was the last original Star Trek comic book to come out before Gene passed, "Where's There's A Will...", by Howard Weinstein, Gordon Purcell and Arne Starr, with cover by Jerome K. Moore, with the original crew working together.... and you can find out about more of the Star Trek comic series here!
Star Trek: The Next Generation #25 (November, 1991) was the last TNG book to come out before Gene's end, and "Wayward Son" by Michael Jan Friedman, Peter Kraus and Pablo Marcos (with cover by Jerome K. Moore) dealt with Worf, his son Alexander, parents Sergey and Helena Rozhenko, as well as the outrageous Okona!
Losing Gene Roddenberry was like losing family....
...but, as Bones said about Spock, "He's not really dead...as long as we remember him".
