Just some moment where you thought heroes really shined as heroes.

Blue Beetle (Jaime Reyes) - Blue Beetle 2006 issues #24 & 25. Fantastic.

Nightwing (Dick Grayson) - Nightwing 1996 issue 19. Not the climax of any story. Just rescues after the earthquake. With thought and caring and endurance. And very much contrasted with Nite-Wing.
