Is Yamcha from DBZ a planet buster?

I think so as he was training with Olibu who was only slightly weaker than Pikkon. Pikkon beat Cell, Freezer, Ginyu Force, and King Cold in hell effortlessly in under 30 seconds. And First form Freezer destroyed a planet 3x the mass of Earth. What do you guys think?

Yes. He was a planet buster at the beginning of DBZ. He was stronger than Master Roshi, who blew up the moon once, but broke a sweat doing so. Piccolo, before finishing his training to face the Saiyans, blew up the moon without even straining.

By the time the Saiyans came around, any of the Z-Fighters could have destroyed the planet.
