Heavy quickly closed in the distance and chopped down his sword from above. To which Billius sidestepped to avoid the blow and quickly threw a punch.
Heavy intercepted the punch with his elbow and followed with a round kick using the force from the punch.
The kick landed squarely on Billius's liver.
Billius was thrown a few feet away by the force of the kick. But he was still standing on his two feet.
Unlike Heavy who was holding a sword Billius was empty-handed. The reason for that is he is a brawler.
When going to war he would always carry a huge war hammer to beat down the enemy. But when having a one-on-one fight he would rather fight empty-handed as the war-hammer would hamper his movements.
