Man, trying to count how many times Earth gets wrecked in 'Dragon Ball Z' is like keeping track of how many times Goku skips a meal—it happens a lot, but the exact number gets fuzzy. The most iconic destruction has to be Frieza blowing it up in the 'History of Trunks' timeline. Then there’s Kid Buu’s infamous planet-busting tantrum, which was reversed by the Dragon Balls. Cell also threatened to do it, but he got stopped. And let’s not forget the near-misses, like when Beerus considered it in 'Battle of Gods.' Honestly, the Earth in DBZ is like a cosmic punching bag—it’s a miracle it’s still standing by the end of Z.
Now, if we dive into alternate timelines and movies, things get even messier. In 'Dragon Ball Super,' Future Zamasu obliterates Trunks’ timeline’s Earth, and there’s the whole mess with the Tournament of Power where entire universes get erased (though that’s cheating a bit). The manga also throws curveballs, like Moro’s attempted destruction. So, if we’re strictly counting on-screen, main timeline destructions, it’s at least twice (Frieza’s timeline and Buu), but with multiversal shenanigans, the number climbs higher. It’s wild how Earth keeps bouncing back like a Saiyan after a Zenkai boost.
