Place this clip right before the main action beat in a battle edit, then follow it with Za Warudo Time Stop for the freeze, and bring in Giorno Giovanna Theme underneath as the fight restarts and your suit takes control.
About this sound
This is Amuro Ray speaking the line 'Nu Gundam isn't just for show' in a short, steady voice clip lasting about three seconds. It feels confident and defiant, like a quiet warning that skill is about to back up the design. It comes from Mobile Suit Gundam: Char's Counterattack, where Amuro pilots the RX-93 Nu Gundam against Char.
