I'd made this Fan Artwork of Princess Cadance back in 2018.

She first appeared in the Canterlot Wedding episode parts 1 & 2 when she is going to be married to Twilight's Brother the but real Cadance was being impersonated Queen Chrysalis in a plan to invade Canterlot in the first part of the cliffhanger until in the 2nd half Twilight found the real Cadance and reunited her with her brother defeating Queen Chrysalis and would rule Crystal Empire giving birth to princess flurryheart.

MLP Princess Cadance Belongs to Hasbro.
