Uh, yeah he is. Once he takes off his power rings and unleashes the ultimate power in the world, he kinda can, but hasn't showed it because Shadow's a good guy. He doesn't destroy planets, but has the power to do so. If some DBZ freak could defeat Shadow, that wouldn't be right. And Shadow's the Ultimate Lifeform. He isn't supposed to fail, he can defeat gods, and he can defeat someone like Vegeta.

And Shadow can destroy a planet with one attack in nere seconds. Read the Archie Comics. The only reason you think he doesn't is because Shadow holds back. And he wears those rings, which make him control his powers. If he were to take them off, he can take out Vegeta and an entire planet in mere semi seconds.
