It could be said that Baki was born to be the best. Yujiro Hanma, the strongest man in the world, fathered him for the sole purpose of having a worthy opponent. Unfortunately for Baki this meant his childhood was not exactly loving. He spent the majority of his life training, often putting himself at risk of death, just to have a chance of matching his father's overwhelming strength.
While Baki's aptitude for battle is perhaps only surpassed by his father, the two are opposites as people. Where Yujiro disregards everyone around him, Baki seems to draw other people in like a magnet. Yujiro believes himself to be invincible, while Baki sometimes lets his emotions get the best of him.
For the dub of the Baki OVA James Carter Cathcart played Baki. For Funimation's dubs of the two Baki TV series Robert McCollum took the role. When animated Baki returned to Netflix the entire cast was replaced and Troy Baker became his new voice.
