“The God of Destruction who sleeps for decades, wakes to erase planets, and will spare the universe for good food.”
Divine-tier erasure — his Hakai can unmake anything, including beings that can't normally be killed.
His ki exceeds Super Saiyan God level — he didn't even compete in the Tournament of Power, but his presence alone is deterrence.
He sleeps for decades at a stretch — destruction only happens when he wakes up, which is mercifully infrequent.
The strongest being in the universe wants nothing more than a good nap and a great meal. Petulant and volatile, but so powerful that everyone else has to orbit him. He's less a villain than a natural disaster. The fact that Goku amuses him is basically the main reason Earth still exists.
