Okay guys, here's my ten:
G.I. JOE - It was the first of the Hasbro cartoons in the Sunbow/Marvel era, and the lead cartoon of the Hasbro Holy Trinity.
TRANSFORMERS - The next cartoon to join its big brother in the Hasbro Triad. Gotta love those Robots in Disguise!
JEM - The little sister of the two other cartoons. A direct spin-off of Super Sunday, it became one of the most popular standalone shows of the Hasbro Triad, and one of the first cartoon soap operas of the 80's (Next to Robotech, of course!). Plus, you gotta love that Kimber Benton so much, you wanna do her!
ROBOTECH - I consider Robotech the first long-form soap opera based in outer space, from its heavy space battles and multiple storyarcs, to the ongoing romance between Rick Fokker, Lynn Minmay, and others, This was a series worth waiting for me.
BATTLE OF THE PLANETS/SCIENCE NINJA TEAM GATCHAMAN - I used to watch this bad boy in 1979 (when it came on WNEW (now WNYW, FOX-5) and 1984 (on WPIX-11), and I used to have a crush on Princess back then. Plus, it was the first show to predate Voltron and Saban's Mighty Morphin Power Rangers with its five-person lineup.
VOLTRON - One the few robot shows that were on the air in the 80's, the Lion Team was the best, and the first one to have an actual princess as one of the Voltron Force pilots in the show!
THUNDERCATS/SILVERHAWKS - These two shows were Rankin-Bass' first entries into the action cartoon game, and one of the many shows to use some of the same actors from each other's shows (Rankin-Bass later produced the similarly-themed Tigersharks series, which dealt with humanoid fish, just like TC with humanoid cats and SH with cyborg birds). Plus somebody had to have had a crush on Cheetara and/or Steelheart at one time (Mine was with Melodia, even though she was a banshee with that damn keytar of hers)!
THE DC ANIMATED UNIVERSE - Credit Bruce Timm, Paul Dini, Andrea Romano, Kevin Conroy and others with helping to bring back the DC heroes from the campiness that was Superfriends with a style that was all their own. From Batman: The Animated Series to Justice League Unlimited, this was the gold standard.
HANNA BARBERA'S SUPERHERO UNIVERSE - Hats off to Joseph Barbera, William Hanna, Alex Toth and others, for creating many of the great crimefighters and adventurers who were part of Hanna-Barbera's World of Super Adventure back in the late 1960's. From Space Ghost to Birdman and beyond, there was a quirkiness to those guys that I liked.
JOSIE AND THE PUSSYCATS - Before Jem, Kidd Video and the Misfits, there were Josie and the Pussycats! these feline-themed beauties had the most sexually-suggestive outfits for their time in the cartoon spotlight, and they were musicians! Plus, I was a Valerie fan, and they had a live action movie for God's sake!
That's my list, deal with it!
