Summary
Mr. 4 is a towering figure distinguished by the number four emblazoned on both his shirt and his weapon. He possesses inhuman strength and serves as a formidable batter, wielding a massive four-ton bat. Due to his dimwitted nature, he rarely speaks and relies entirely on his partner, Miss Merry Christmas, for guidance. He is accompanied by Lasso, a dog who was formerly a human gun that consumed the Inu Inu no Mi. Lasso now assists in combat by firing explosive baseballs, which Mr. 4 then hits at his opponents.
