I stumbled on this while surfing around the IMDB:

Markie Post as Electra Woman!
For some unknown reason, I was singing the song from this show just this morning. It goes a little something like this: “Electro-Woman and Dyna-Girl! Electro-Woman and Dyna-Girl!” Now that you know the words, you can sing along.
And it had a companion show (which I also thought about this morning, apropos of nothing), “Wildboy and Sasquatch” or something like that. Maybe it was bigfoot. Whichever, it was post-apocalyptic, and the wild boy was armed with a lasso. (Not to be confused with that other post-apocalyptic superhero from the 1980s, Thundarr the Barbarian.)
Strictly speaking, this is a 1980s hero. I remember because it premiered around the same time Hinckley shot Reagan in early 1981. Thus, the main character of Mr. Hinkley became Mr. H.
Shazam! is the magic word that Billy Batson speaks to turn into the hero, who’s named Captain Marvel. Who was on the air in the 70s but was created decades earlier.
Damn!! Forgot Bigfoot and Wildboy! Oh yeah and Dr “David” Baner (AKA The Hulk)
Mr. Terrific and Captain Nice. Or were they late '60s?
Someone already covered the Hulk, kingpengvin.
There was a show called Gemini Man in 1976, about a guy who had a watch that would turn him invisible for 15 minutes at a time. He should count.
Does anybody remember a group of superhero cartoon guys that included a baby who would hit you with his bottle, a rope guy and a cuckoo guy?
I have a vague memory of thinking the cartoon was hilarious, but I was just a wee Biggirl and my judgement at the time has proven to be less than refined over time. (I actually loved Scooby Doo and the Teenaged Flinstones with Captain Caveman. Yeuch!)
There was a show called “Plastid Man” based on the DC character. In the last season they introduced a hideous “Baby Plas.” I don’t remember any specific bottle-hitting, though. One of the “super-globetrotters” could turn himself into a rope-man. Cuckoo guy? You got me.
There was also the “Drac Pack,” teenage monster types who fought older monsters; “Ghostbusters,” with Spencer, Tracy and Kong (one of whom–not Kong–was a gorilla); and something I want to say was called the “Super 7” which had seven different superheroes and teams in rotation (including Batman and Robin with Bat-Mite, an animated Isis with “Hercules” and “Mercury” (who was black IIRC), and a black duo, a woman who could shring a la the Atom and a guy who could stretch like Plastic Man).
Yes, yes! Wasn’t one of them Diaperman?
I also remember watching Underdog when I was little, but that might be a '60s cartoon in which case I am showing my age.
Space Ghost! And Frankenstein Junior (junior-junior-junior…) Ugh, those cartoons were terrible.
I must add here that I worshipped the Bionic Woman. I wanted to live in Ojai, California, and be named Jaime Sommers. I wanted to grow up and live in a cool apartment over a barn. And work for the OSI. She shaped my life. 
One thing I could never figure out, though – how does a skydiving accident necessitate the implantation of a bionic ear?
And speaking of Bigfoot, anyone remember the Bionic Woman/$6 million joint episode (Or maybe Steve guest-starred on BW) where the two of them take on Sasquatch? And it turns out he’s really … what? An alien? Bad guys dressed up? I can’t remember.
I remember it very well. Bigfoot was a robot.
(Played by Andre the Giant, if I remember right.)
You wanted to be the Bionic Woman, but I was the freaking Bionic Man. I had the red sweatsuit, sneakers, squint, everything.
When I ran, I did it in slow motion, and I made the “cha-cha-cha” noise. When I jumped, I went “whhaaaaaa-thumpppp.” When I looked into the distance, I went “boop-baa-baa-baa.”
