Final Explosion

The Final Explosion is a Kamikaze technique used as a last resort.

Other World Series
In the Other World Series, Master Kai tells his students about this technique, but strongly advises them not to use it under any circumstances as such a technique will cost them their lives and may or may not deal with a threat entirely.

Hero: The Guardian Smurf stories
In the HERO: The Guardian Smurf story series, this technique is used only once by Hero as a last resort against Gargamel when he fully acquired his ki powers and became "Super Gargamel". In order to make the attack more effective after acquiring newly found God powers, Hero asked Brainy beforehand to re-created to potion used that made Hefty almost human sized. Hero survived the explosion as his new God powers allowed his body to become more resilient to the blast, albeit feeling extremely exhausted afterwards.
