When a hero has pushed him/herself too hard physically and abruptly starts a physical breakdown. That one of these is coming may or may not be clear in advance, but when it starts, it will hit all at once. Injuries sustained during Heroic RRODs should range between serious and fatal if left untreated (although rarely crippling), possibly leading to a case of You Are Already Dead. Also a common cause of You Can Barely Stand. This is the Heroic Red Ring Of Death. Named after a warning signal on Microsoft Xbox 360 consoles. A Sister Trope to Power Strain Blackout (when the cause is not as serious).
