The best way to describe Mimicry is unhinged.
She's the polar opposite of her little brother and is the kind of stupid that's either frustrating or endearing. She's shorter than the average mare but what she lacks in height she makes up in audacity.
Mimis likes to party and isn't exactly a stranger to law enforcement, much to her parents dismay. She was raised by Flash's sister in Cloudsdale as Mimis liked to race and wanted to be the next Rainbow Dash. She tried but fell short as while she's fast and insanely talented, she lacks the motivation needed to qualify for the Wonderbolts. Her track record of disorderly conduct didn't help matters. From downing 5 energy drinks on the day of her flight exam leading her to ace the event but vomit on her idol Rainbow Dash, bitting a stallion for cheating on her bff or getting in a screaming match with her Bio teacher over the validity of penguins being birds, Mimis was a problem child. She used to get into fights a lot as a kid as well and normally never won but her motto was and still is "I won't win, but I'm gonna do damage and leave scars.". She's calmed down as she's gotten older but her antics in her teens has familiarize her with Cloudsdale police department whom she affectionately calls her "popo-pals"

When she's not partying or being an overall menace, she likes to carve wood sculptures and masks. In fact, the mask Eblis wears was made by Mimis. She's very artistic and gets extremely hyped when art exhibits open up in her area or really anywhere in Equestria and beyond. She now has a studio in the Crystal Empire but really just couch surfs and hasn't settled on one place. In spite of her disruptive years in school, Mimi knows over 7 different languages and can easily communicate with other creatures. She taught herself how to speak languages to learn how other cultures create works of art. She's insanely protective of her family members and regularly just appears out of thin air to torment her fathers. Her family are pretty quiet people so she often speaks for them usually by first screaming "I SPEAK FOR THE TREES" which always makes Flash laugh and makes Sombra die a little inside.

She's eccentric but time and exposure to new creatures is making her a more well-rounded mare. She will happily shank you if you hurt her family or friends and that will never change.
