Retired Philippine Navy (PN) Commodore Rex Robles, who was a key figure in the EDSA People Power Revolution that toppled the late dictator Ferdinand Marcos Sr., has reportedly died at the age of 75.

In a report published by ABS CBN News online, it said that Robles died of cardiac arrest at 1:30 a.m. Sunday as confirmed by his wife, Marilyn.
Robles was a member of the Philippine Military Academy (PMA) Class of 1965.
He was among the leaders of the Reform the Armed Forces Movement (RAM), a group of military officers who sought to implement major changes in the military which was accused of being corrupt during the Marcos presidency.
The RAM, founded by retired Army colonel and now Information and Communications Secretary Greg "Gringo" Honasan, was instrumental in the 1986 People Power Revolution as well as the launching of several coup attempts against Marcos' successor, the late Corazon Aquino.
Robles was also part of the Feliciano Commission, a fact-finding panel headed by former Supreme Court Justice Florentino Feliciano which was created to investigate the Oakwood Mutiny of July 27, 2003.
It involved a group of 321 armed soldiers led by Army captain Gerardo Gambala and Navy lieutenant second grade and former senator Antonio Trillanes IV who took over the Oakwood Premier Ayala Center, an apartment tower in Makati City, to expose the alleged corruption in the administration of then President Gloria Macapagal Arroyo.
Robles was also appointed by President Duterte in 2018 as a member of a panel tasked to review the 1987 Philippine Constitution for the purpose of establishing a federal charter.
With the passing of Robles, messages of condolences were expressed on social media.
Among them were PR practitioner Malou Tiquia who wrote on Twitter, "RIP Comm. Rex Robles," and National Task Force on coronavirus disease (NTF COVID-19) adviser Dr. Teddy Herbosa who commented "RIP; Condolences to the Robles Family."
Meanwhile, Business Mirror columnist John Mangun said, "Rest In Peace Rex Robles. A reminder that life is short and often sucks. We were all winners because he lived."
