Marcelito "Mars" Castro Pomoy is a Filipino singer, known for his ability to sing in both tenor and soprano. He is the grand winner of the second season of Pilipinas Got Talent.

Pomoy was born in Imus, Cavite and raised in Bislig City, Surigao del Sur. When he was young, his father was incarcerated while his mother left him alone with his younger sibling and went to Manila. He was later adopted by a police officer and did odd jobs when he was a teenager. Later on, both his biological father and mother had separate families on their own. Pomoy had discovered a talent of his while doing poultry work: singing in both a male tenor voice and a strikingly convincing female soprano voice. This paved the way for him to join different contests in both the amateur and professional leagues. He tried his luck in Talentadong Pinoy, but regrettably did not make it. He later joined the second season of Pilipinas Got Talent (PGT), and by this time, successfully made the cut.

Pomoy's success on PGT led to his being a contestant on the second season of America's Got Talent: The Champions, beginning with episode 2 which aired January 13, 2020. Pomoy makes regular appearances on ASAP, and his first studio album, entitled Duet Yourself, was released in 2011 under Star Records.

On September 21, 2014, Pomoy married Joan Paraiso of Calauag, Quezon, and they have one daughter, Marcella Janiah
