TheHero and the {{Villain}} face off in battle. They both pull their weapons and [[SingleStrokeBattle charge at each other]]. After the first blow we see a shot of the floor beneath one of the combatants. A stream of blood trickles down. This is a common way to show that the battle is serious and one of the characters is injured. Often the next shot will be of the injured party touching their wound and saying "I'm bleeding?" A common trope in any show that involves a lot of bleeding. Sometimes a BloodUpgrade results from this.

Got jack all to do with the first ''{{Rambo}}'' installment of the same name, or the sequel, ''[[OddlyNamedSequel2ElectricBoogaloo First Blood Part II]]''.
