Place it near the end of an edit, just after the struggle peaks and before the final outcome lands. Open the sequence with Danger Alarm Meme Sound to raise the stakes, follow with this clip as the last warning, then close with Inception Horn Sound Effect when the defeat is confirmed.

This is the repeating alert that warns Ultraman is almost out of power, a short pulsing signal just under five seconds long. It feels tense and urgent, like a countdown with almost no time left. It comes from the long-running Japanese Ultraman series, where the hero can fight only while his energy lasts, so the warning means defeat is close.
