He is known as "the Toughest Guy on Earth" (地球一のタフガイ, Chikyū Ichi no Tafugai).
Because of his lifestyle, as muscle for hire, he has a fierce personality and a taste for the high quality things such as cigars and martini's. He also possesses a short temper and won't stand for holding back.
He has grey hair in a short hairstyle, he wore a tuxedo and a bowtie, underneath his clothing like many of the fighters he has a muscular build.
Richard Filth's main strength is his toughness, aswell as a high pain tolerance. He has shown to be able to take heavy hits from Doppo and still be able to fight back. Before his fight with Doppo, he had three men beat him with bats, which he took with out even moving or having made a sound. He then told them, that if they held back again, they would have to spend the money he paid them on reconstructive surgery. They then hit him hard enough to break the bats and he just shook it off nonchalantly. His main strategy when he fights is to let his opponent wear themselves out beating on him and then knock them out with one punch.
