Okay, so I decided to explain why does my cutie mark look so similar to Zipp’s. Back in 2019 when I first started watching MLP G4, I was enchanted by Twilight Sparkle, I like her so much that it made influences on my OC. I chose alicorn to be my OC, and gave him those beautiful rose-pink belt like Twilight on the mane and tail, finally I designed a cutie mark, basically it’s a copy of Twilight Sparkle’s cutie mark, but used lightning symbol inspired by the Flash. After a year, I thought it was a bad idea, I didn’t want him to be another Twilight Sparkle, so I changed the hair style and the cutie mark, and worked harder on his story. I took off the Hexagram and keep the lightning only, then I thought how about keep the two colors? So there came two lightning symbols, one in the front, another in the back. At that time, G5 was about to announced in after 6 months (if my memory is correct). So it truly has nothing to do with Zipp. In fact I was shocked a little when I saw Zipp at the first time, but it was really an interesting coincidence.
