Iona is a changeling. She's quite tall, but not as much as Chrysalis or Celestia. Her mane and tail are longish and green, with holes. Her legs also have holes in them, towards her hooves. Her carapace and the bands that go across her flanks and stomach are green, while her eyes are also green with black vertical slits for pupils. She is a little bit pudgy, but has lost some and doesn't seem uncomfortable with her weight.
Iona's Backstory, Part One
As a foal growing up in Canterlot, Iona was constantly surrounded by the most
upper-class ponies any could meet. They lead rich lives, ate expensive gourmet
foods, wore the most luxurious clothes any pony's money could buy and did all sorts of rich things, puzzling the little foal. She couldn't understand why everypony was so uptight and didn't laugh or play.
Her father, once a royal guard in the palace, started teaching her at a young age how a proper pony should act. What to say, how to say it, how to act, how to dress, how to eat and most importantly: NEVER get dirty. Supposedly born to a pegasus father and a unicorn mother, Iona's care was given over to her god parents when everyone else moved back and forth between Canterlot and Cloudsdale. She continued to grow under their guidance and became just what her father had hoped she would become.
A prim pony with proper manners but snooty and high-class nonetheless, as is not too uncommon a sight in Canterlot. And yet, underneath all of her training about etiquette and how she should be, Iona felt conflicted. She didn't want to know the proper way to eat or the correct method of conversation. She still just wanted to make friends and have fun, despite it being frowned on by the vast majority of the city's populace, but continued to do as they said and acted as they expected her to. For that was what her father wanted. Eventually, Iona decided that she wanted to leave Canterlot and made her way to Ponyville, having heard that some ponies she used to know could be found in the town as residents.
Iona's Backstory, Part Two
After a finding her siblings in Ponyville and falling in love with a local pony, Iona settled down in the quaint little down and slowly allowed the years of forced etiquette to melt away as she eventually adopted two lovely fillies with her significant other. Not to say that she didn't remain proper and polite, but she certainly was nothing like the snobs in Canterlot anymore. Unfortunately (or fortunately) an accident occurred during a unicorn ritual that would have allowed her to display enhanced magical abilities and robbed Iona of all of her energy, revealing her to be an insect-creature known as a changeling.
Initially in denial, she came to accept her own body in subsequent months and learned from her parents that they had known all along. Despite a bit of public backlash, Iona came to settle down in Ponyville again, accepted as the town's residential (and benevolent) changeling.
