Alexander Gallen is shown to be very confident and proud, due mostly to his inhuman strength and abilities. He looks down on most, if not all, of the other competitors of the Maximum Tournament, but finally he was defeated by Jack Hanma. He is also shown to be very patriotic, viewing himself as a tool for his motherland.
Alexander Gallen is superhuman strong. He can using a 100 kg axe and cutting trees with a single swipe. Alexander also can lifting the trees with his hands. He always wears a special titantium sackles to restrain himself. He could dig a near-meteor size hole and lift a cart full of rocks while going up a hill. Gallen could beat a giant anaconda with a few wrestling moves and kill it with a few punches and a stomp onto the head of the anaconda. Gallen is a quick learner. He became a world champion wrestler despite not practicing in any wrestling gyms. He also can using other types of combat, such as boxing. He is also shown to be very skilled in gymnastics during his fight with Jack. Gallen has amazing durability: he survived after Jack Hanma stabbed his heart using Gallen's ribs and survived after being bite by an anaconda. In the second series of the manga, he nearly gets killed by Sikorsky, but probably that's because Gallen was wounded and could barely walk after the Maximum Tournament.
