Moses the Changeling

"Moses. The friend of Eclair Creme, Rarity, Babs Seed, Sweetie Belle and the rest of the Canterlot elite and the other high-class ponies who were concerned about the How I Can Help Make the World Great and its dire consequences that are unknown to mankind... and ponykind. He's from the Changeling Federation, and i pray that he could infiltrate the blasted ceremony with his disguising skills.."

--Su Ji-Hoon, The Little Changeling That Should

Moses (real name: Park Min-jun) is a young metamorphosed male changeling who lives in Gyeongyeong, Su Ji-Hoon's hometown. He works for the Interpol and the Korean National Police on infiltrating the How I Can Help Make the World Great ceremony (as disguised as Eclair Crème), as per request by Eclair Creme, Rarity, Babs Seed, Sweetie Belle and the other rebellious Canterlot elite who refused to attend the special ceremony (during Operation Evil Eye, where the Grand Alliance deploys changelings to disguise as declined guests on spying the ceremony).

Hence his name, he is also part of the Catholic faith.
