My fursona is Teal Skeletore (in my avatar), she has arrow like markings that kind of look like ribs. It's to represent that I'm really thin in real life. The black and white tie, the necklace that she wears on her ankle has a Kingdom Hearts logo heart on it and a silver key, and the gold bracelet on her other ankle I all own in real life and have some kind of emotional attachment to (I also own the glasses, and I want to get a lipring when I'm older). Her last name Skeletore comes from my friend in real life who sometimes calls be that because I'm so skinny. She's made of all my negative emotions, and she's very obviously insane and unstable.
The target like marking on her neck has two swords sticking out of it, when I draw her in human form her weapons are twin cutlasses.
My male fursona is Teak. He's a white tiger with light brown stripes, and I thought of him when I kept doing typos and writing Teak instead of Teal. He's made of all my positive emotions and he balances Teal out and keeps her in check. He has no apparent accessories or anything like that. He's simply there.
Teak and Teal have a strange relationship, they can be depicted as siblings, best friendsI, lovers or enemies. It all depends on my mood. I also sometimes draw Teal as a white tiger with teal stripes to fit with Teak.
