As a writer, I've taken quite a few shots at fan fiction over the years, and Elongated Man has been a subject for a number of them. People seem to like them, so how about I link to them here?
Up first is a trio of stories that tried to imagine what Elongated Man would be like on The Flash TV series. These were written before Season 3 began, long before we heard Ralph would appear in Season 4.
A New Stretch: Ralph Dibny's origin reworked to fit in with the show, and it even explains his presumed death referred to in Season 1. Ralph is already romantically involved with Sue and uses Gingo extract to trigger his powers.
The Soured Superpower: As a follow up to the first one came this sequel based on The Flash #252-253, "Double Dose of Danger!" and "Don't Mess With The Molder!" Due to a problem with his gingo extract, Ralph takes on a villainous persona and gains the power to reshape anything he touches.
Ralph Dibny vs Plastic Man: Capping off my trilogy was a tie-in with an Arrow fan fiction that introduced Plastic Man in that world. Meeting up at S.T.A.R. Labs, Ralph and Plastic Man take on challenges Cisco devised to see who's the better hero.
Next up is a couple of fan fictions written to tie in with the show's version of Ralph.
Ken and Ralph Dibny: Brother's Keeper: This story tried to reimagine Ralph's brother Ken (revealed in Secret Origins (Vol. 2) #30) as fitting in the show's continuity. Please note that it was written during Season 4's winter break. As such, the show would go on to suggest that their Ralph was a single child and his parents had split up, so this story doesn't fit in continuity anymore. It contrasts two encounters between Ralph and his older brother, once when he helps Ralph move to his office, and again when Ralph visits his hometown after getting his powers.
Teddygram for Amunet Black: It took me awhile to write this story, it was originally going to be during the winter break, but was soon revised and was released after the next break after Ralph confronts Amunet a second time. So this one presents a story where he encounters her again as she has captured Cisco and it's up to Ralph to rescue him.
Finally, here's two that are just based on the character as seen in the comics.
Mystery On The Mulberry: I was commissioned to do a story in which Ralph and Sue go on a cruise and solve a mystery and various mishaps ensue that see Ralph's powers used in funny ways. This could work as a fourth story to my reimagined Ralph and Sue for The Flash TV show, but on the other hand, it also just works for the standard DC universe from the comics. The story introduces original characters for fellow passengers on the cruise, including Dave and Jeremy, a gay couple, Jeremy being the webmaster of a site titled Hot Heroes. The commissioner liked Dave and Jeremy and has since used them in his own projects.
The Midnight Prowl in Star City!: The commissioner of the last story and I did an RP session in which we wrote out a story by controlling specific characters. The story sees Ralph (me) and Roy Harper (him) team up to rescue the Green Arrow.
Changing up, ElectricKittenShark, who wrote a brilliant piece about Ralph on The Flash TV show that we shared sometime ago, also writes fan fiction about Ralph and Sue. These take place in a universe based on the show where Sue is also a metahuman with empath abilities. The style of writing is different from my own, and these being considered possibly canon is likely out of the question, but until the show gives us Ralph and Sue for real, these make a fun read.
Starting up is a series titled So Sue Me! that introduces this version of Sue and has several misadventures with her:
