The late great Canadian cartoonist Randall Holmes’ unforgettable '70s hero, Harold Hedd.
Both Brother Power, and Prez reapeard in Neil Gaiman’s work.
Here I thought I’d be the first to mention him. Looks like I’m third. Might as well elaborate a bit for those that haven’t read the books.
Cap’n Trips (a.k.a Mark Meadows) is the owner of a Head Shop blessed with the superpower (via the alien virus responsible for all superheroes in Wild Cards) to transform into various other personas with super powers, by taking assorted drugs. Each combination of drugs triggers a different persona until it works its way out of his system after an hour.
The personas are named:
JJ Flash (Fire powers)
Moonchild (Female Martial artist with a Yin/Yang on her chest)
Cosmic Traveler (Illusion, intangibility, and telepathy)
Starshine (Light mainpulation and Strength)
Aquarius (Water powers, dolphin form)
and
The Radical
Conclusion: Mega-hippie.
Does Zaphod Beeblebrox count? He’s kind of a hippie…
(and apropos of nothing, the post count for this thread right before I posted this stood at 42…)
While not precisely hippies, the ler from several M. A. Foster books (“Warriors of Dawn”, “Day of the Klesh”, and another I can’t remember the title of) semi-qualify. They were created as a result of genetic tests aimed at creating “supermen” but which in the end simply created an “other” human race. The ler had a hyper-sexual drive coupled with a low pregnancy rate because the geneticists were basically pervs. Add to that a relatively small population in the first place, and they were forced into multi-partner communal living in order to further the “species”.

Half the characters in any Spider Robinson novel. Particularly the ones that are copies of Spider Robinson.

I second this. By temprament, almost every denizen of Callahan’s, Mary’s Place, or **The Place ** is a hippie.
In case anyone’s interested, here’s Warriors of Dawn on Amazon.
One of the comments was “It doesn’t hold up over time.” It didn’t hold up then, either.
After seeing all the Niven and Niven/Pournelle characters mentioned, I can’t believe I’m the first to bring up Harry Reddington from Footfall. A biker amd societal dropout who saves a congressman’s wife (after travelling from California to Kansas during an alien invasion), is the first human to capture one of the attacking aliens (and he did it singlehandedly), and ended up crewing on the spaceship the Americans build to fight the aliens in orbit (and he saves the ship from certain destruction and by so doing, wins an interstellar war).
Shaggy & the Mystery Machine gang! Think of all the crotchedy old men who would have gotten away with dastardly ghostly hoaxes if not for those meddlesome - not to mention nomadic, groovy, hallucinogenic (they have conversations with their dogs!) - kids!
From Stargate: SG-1, season 2: 1969.
Slightly spoilerific plot summary from GateWorld .
The basic idea is that SG-1 pulls the old temporal sling-shot so beloved of Star Trek accidentally, ending up back on Earth in 1969. They end up hooking up with a pair of hippies to make their way across country to find the Stargate to make their way back to their own time. Not only do our heroes dress as hippies but the two they hook up with also help to save the day, thus becoming heroic.
The main character (I don’t remember the name) of the Spellsinger books by Alan Dean Foster.
A hippie college student is transported to a fantasy world where he can cast spells by using his guitar.
Lots of animals walking around like humans (the wizard who brings him over is a turtle) and other odd stuff.
I’m don’t know if I’d call it heroic, but in the computer game Homeworld, at one point you cross through a nebula to avoid detection from your enemies. What you don’t count on is that the nebula is inhabited by annoying space hippies who consider your mere presence there an affort to the nebula(which they call, the “The Garden”). Unfortunatly, leaving is out of the question, so you have to join them, kill them or die.
His name is Jon-Tom. These books also brought us friend Clothahump. 
Hmm. Would Buckaroo Banzai count?
Holy shit! I had totally forgotten about those books! I used to own them! I wonder what happened to them, as I’ve never thrown away a book in my life.
Well, except for my French language workbook.
James Coburn flirted with hippie lifestyle in both THE PRESIDENT’S ANALYST and the OUR MAN FLINT movies.
Professor Trelawney in HARRY POTTER is an academic hippie if I ever read/saw one.
Dr. Stephen Strange has all the accoutrements of hippie-ness, including his funky guru/valet Wong and that groovy pad in Greenwich Village.
S.M. Stirling has used hippie characters in several of his books.
Shea & Wilson’s ILLUMINATUS TRILOGY- Duh!
I got you all beat. Peter St John, aka Mandala, in Grant Morrison’s Zenith series which used to run in 2000AD: he was a member of hippie superhero squad Cloud 9, and dropped acid with the Beatles and sat at the feet of the Maharishi. Of course, he later sold out and became a Machiavellian Tory cabinet minister, but when the chips were down was still a dab hand at thwarting the Nazi minions of the Elder Gods and their plans to enslave the world.
