Black Bolt and Thanos are both powerhouses in Marvel, but comparing them is like weighing a scalpel against a sledgehammer. Black Bolt's voice can level cities with a whisper, and his combat skills are elite—but Thanos? That guy tanks universe-ending threats without breaking a sweat. The Mad Titan's durability, cosmic energy manipulation, and sheer strategic brutality put him in a different tier. Remember when Black Bolt blasted him in 'Infinity'? Thanos shrugged it off like a minor inconvenience.
That said, in a purely sonic ambush scenario, Black Bolt might stun Thanos momentarily. But in a prolonged fight? No contest. Thanos has survived Black Bolt's full scream, the Phoenix Force, and worse. It’s less about raw power and more about how Thanos adapts. Dude’s a walking extinction event with a grudge.
