My Hero can be seen on BBC America, as well as on some PBS stations. If you aren't lucky enough to catch it on either of those, I'll try to give you an idea of what it's like.
My Hero is a BBC television sitcom about an alien from another planet living on Earth with an Earth woman, and the wacky things that ensue...
...and pretty much there is where the parallels between My Hero and Mork and Mindy end.
The alien in My Hero is named George Sunday, but he's also the super-hero Thermoman, from the planet Altron. Altron sends their citizens to planets throughout the universe, armed with super-powers, in an attempt to help out all the civilized planets.
Thermoman's powers include super-strength, flight, various heat-related powers, super-breath, mind-reading, the ability to erase memories, cure people of alien diseases (by kissing them -- a side-effect of this is that if he does it too much, he transfers some of his powers to them), and a host of others that come into play as needed. The extent of his powers isn't really important... we know that he can fly fast enough that when he smells an emergency on the other side of the planet (yes, that's right, I said he smells emergencies) he can fly there fast enough to save the day.
George lives with Janet Dawkins in Northolt, England. Janet is a nurse at the Northolt Health Centre, and they met when Thermoman saved her from falling into the Grand Canyon. After this rescue, and she returns from her vacation, George relocates to Northolt to open a health food store and to pursue Janet. The two quickly fall in love, move in together, Janet becomes pregant with their first child, they marry (minutes before their son, Ollie, is born -- that pregnancy lasted about three weeks, I believe), and eventually they have a second child, a daughter named Cassie.
Janet's boss is Dr. Piers Crispin, a general practitioner who appears to be less interested in healing and curing people than he is with making it big in television. As the series begins, he's a regular feature on a morning news/talk show, but as the show progresses, he makes several attempts to get his own program.
Also working in Janet's office is Mrs. Raven, who is probably the most evil sitcom character in the world. She lives to make people suffer; she's cruel, rude, insulting, and considers her triplets to be the ultimate curse in her life.
Ollie, George and Janet's son, is able to speak from the moment he's born (actually, even before he's born), and displays several of George's powers right away, from flight to even being able to smell disasters. I've only seen one episode with Cassie, the second baby, but Wikipedia says she has the ability to see the future.
Other characters on the show are Janet's parents -- Mrs. Dawkins thinks Janet's made the biggest mistake of her life marrying George, and still hopes that she'll leave George and marry Dr. Crispin instead. Mr. Dawkins doesn't care that much for George himself, but I think he hates his wife even more!
George and Janet's neighbor in the flat across the hall is Tyler, who's a complete space case... I don't know if he's just psychotic (not dangerously so, though) or if he suffers from mental burnout from drug use. Tyler is one of the few people who knows George is Theroman, and refers to George as "Master." Tyler has several voices in his head, and thinks of them as individual people that only he sees. He's also certain that he's been abducted by aliens several times, that he has a cottage on another planet, and that Dan Dare, Pilot of the Future is real (well, he thinks most science fiction characters are real).
The only other person on Earth who knows George is Thermoman is George's cousin, Arnie, who used to be Earth's hero before George, Polarman, until he got his powers taken away for charging people to be rescued by him. When the series starts, Arnie's running a diner in New York City, but later has relocated to Las Vegas, running a casino/bar before moving to Northolt. Arnie and Mrs. Raven have a bit of a love affair going on.
Now, so far as the stories go... well, you rarely see Thermoman in action, aside from some flying around. Thermoman isn't involved with crime fighting at all, but is more focused on rescuing people from disasters.
Some of the regular gags in the show relate to how certain English words and names have completely different meanings on Altron, Tyler's talking about these adventures he supposedly had, and so forth.
It's really hard to try to get across in text here just why I enjoy watching this show so much... I suppose part of it is that it could well be the first real successful live-action superhero program in a long time, but really, it's that it's honestly funny!
If you want to read more about the show, I suggest reading the Wikipedia entry, which also has links to some other My Hero pages.
I was hoping to maybe find a YouTube clip to share here, but it appears I'm out of luck!
