ki

Here is an expanded reference guide covering a wider range of Dragon Ball characters who utilize this iconic, expression-driven internal energy (ki) release—triggered through vocal strain, sharp breath control (kiai), and bared teeth rather than traditional hand gestures:

• The Core Mechanic: A specialized discharge of ki or kinetic shockwaves driven entirely by internal pressure, facial tension, and vocal force rather than physical hand alignments or martial arts forms.
• Visual & Onomatopoeic Style: Characterized in the manga by a tense face showing clenched, prominent teeth, often accompanied by jagged sound-effect text bubbles representing a sharp hiss, grunt, or strain like "HIIHH!" or "SHHH!".
• Nappa: The prime archetype for this display, famously using this method during the Saiyan Saga to trigger massive ground-shaking explosions or wide-area devastation simply by baring his teeth and letting out a sharp vocal burst without moving his hands.
• Vegeta: Frequently employs this explosive energy release during moments of sudden rage or when generating an instant aura burst to shock away nearby opponents.
• Son Goku: Utilizes this expression-driven release during intense close-quarters combat or when rapidly discharging compressed ki fields from his body.
• Raditz: Employs similar visceral, vocalized force to project invisible kinetic pressure waves and push back combatants during his initial skirmishes on Earth.
• Cell (Perfect Form / Super Perfect Form): Often uses tense, teeth-baring power-up pulses accompanied by sharp vocal strains to expand his aura and establish sheer dominance on the battlefield.
• Broly (Both Classic and Modern Versions): Regularly channels raw, unbridled fury through deep-set facial tension, bared teeth, and sudden vocal roars that instantly detonate shockwaves around him.
• Majin Buu / Super Buu: Occasionally channels sudden bursts of chaotic energy through abrupt, aggressive facial contractions and high-intensity vocal snaps rather than formal charges.
