Edwin José Cornier Colón was born on October 1, 2002 in Mayagüez, son of Harold Cornier, and engineer, and a mother who is a pharmacist. He has mentioned that since he was a child, especially from the 2012 elections, he has been interested in being part of politics and as a consequence of the government's response to Hurricane María and 2019 Puerto Rican protests, he was inspired in launching his candidacy under the "Movimiento Victoria Ciudadana" (Citizen's Victory Movement, MVC). He is also a surfer and practices standup paddleboarding, having been a member of Puerto Rico's national team and participating in international competitions. Additionally he is a "junior pro" in Flying Fish Board Co. Currently, he is completing a bachelor's degree in geology at the University of Puerto Rico at Mayagüez, though he has also expressed completing studies in political sciences. His intention is to at some moment become Aguadilla's mayor.
