Put it at the start of a power-up sequence, then cut to the transformed form and follow it with WTF Boom for the impact, or hold the moment with Za Warudo Time Stop before the reveal.
About this sound
This is a 14-second clip of Broly beginning his monster transformation, with rising roars and surging energy building as his power breaks loose. It feels tense, wild and overwhelming, like watching a fighter lose control in real time. The moment comes from the non-canon version of Broly, before he fully unleashes his transformed form.
