Place this countdown at the end of a build-up sequence, right before the action shot. Follow the lift off beat with a run vine for a character sprinting away, then add a yaaaay cheer once they actually make it clear.

This is a roughly five-second voice clip of a character counting down 5, 4, 3, 1 before yelling lift off, skipping 2 entirely. It feels frantic, overexcited and deliberately absurd, like a launch that cannot wait for the proper sequence. It comes from Origami Almighty's Fosh Beary, a parody of a controversial MUGEN character.
