Killing Makes You Stronger? I'd Rather Work at Impel Down

After transmigrating to the world of One Piece, Carl acquired a Hunting Notebook. Killing targets recorded in it made him stronger.

So Carl decisively chose to take a job at Impel Down.

Kill a physical powerhouse, and his physique improved.

Kill a Haki master, and he developed top-tier Haki.

Years later, when Carl's deeds came to light, the Navy was shocked to discover that he had become an out-and-out monster.

Sengoku: "If Carl hadn't defected, he would have been the perfect person to take my place."

Kaido: "Compared to me, that kid Carl is the real monster!"

Robin: "Carl, what kind of man are you, really?"

At Marineford, looking down at the battlefield that had fallen abruptly silent at his arrival, Carl smiled. "I have a proposal. I haven't even told you what it is yet, but first, who agrees and who objects?"
