kukulkan_(fate)
The king of the South American Lostbelt in Fate/Grand Order. Later introduced as a playable Foreigner-class Servant. Designed by Hiroe Rei and voiced by Suwa Ayaka. In reality, she is the ripped out heart of Lostbelt ORT (type-moon) worshipped into becoming a sun goddess. Her personality and design are based off of Quetzalcoatl (fate), so their mannerisms are rather similar.
