My elemental ladies: Sapphyre and Gemini!
Water and fire may seem like complete opposites, and Gemini is certainly far more 'hot-headed' and snarky than the more level-headed, and more subdued Sapphyre, but these two have their similarities.
One of them being they each started off as "me."
Sapphyre came from a dream I had where I was a mermaid. After years of drawing her in random illustrations, she finally got her own story, "Sapphyre the Mermaid" where she falls in love with someone who looks remarkably like my husband... ;)
Gemini started off as the stand-in for me in The Gemini Archives, a really big Doctor Who fanfiction I wrote for a number of years. She's since (finally) found her own original story in "Westfall" that I'm currently working on.
And yes, this means it's super easy for me to cosplay as them both ;) And while they both carry aspects of my personality with them, they've come to be their own unique characters whom I love quite a bit.
