(Edit: updated to include the following information)

Before you ask, I did NOT intentionally steal ILoveKimPossibleALot's OC. I created Oceanblue back in 2012 (her original name was Helios, and her cutie mark was a sunflower,) before I even had a DeviantArt account and at least a year before I knew who ILoveKimPossibleALot was. And yes, I know they have a YouTube, but I created my OC at a time when I wasn't very active in the community and didn't watch any pony videos. When I created her, my favorite color was aqua and I had brown hair with highlights, so it felt obvious that I should make an OC with those colors. As far as I know, the colors (and sometimes the hair style when they decide to draw her with curly hair) are the only similarities between the characters. We have very different cutie marks and stories. I will not change Oceanblue and I don't expect ILoveKimPossibleALot to change their OC. And most importantly, I've discussed this with them, and they don't mind it.
