Place it right after the explosion in your edit, then follow it with WTF Boom for extra impact, or cut to SpongeBob Boowomp when the failure turns awkward. For a slower reaction, pair it with Awkward Moment after the blast settles.
About this sound
This is a short five-second voice clip of Broly sheepishly asking if he just blew something up, delivered in a surprised, almost apologetic tone after the damage is already done. It feels funny and awkward, like a huge, powerful character suddenly realising he went too far. It comes from a non-canon Broly moment, which makes the casual understatement even funnier.
