Battle Beast is so strong mainly due to his superhuman strength, durability, and combat skills, which are comparable to the elite Viltrumite warriors in the Invincible universe. He is physically powerful enough to defeat strong opponents like young Mark Grayson and the Guardians of the Globe, and hold his own against Viltrumites, even seriously injuring them. His abilities are amplified by his feline attributes such as fast reflexes, claws, and fangs used for inflicting serious damage. Battle Beast is not only strong but highly skilled in various forms of combat, having mastered all fighting systems and weapon use. Additionally, Battle Beast suffers from a literal blood curse that gives him an unquenchable thirst for violence and conflict, which drives him to seek out powerful foes and battle against them ceaselessly. This curse likely enhances his strength and ferocity, a trait passed on to his daughter as well. He is also incredibly durable and fast, with abilities like surviving in space and having superhuman endurance. His whiskers aid in sensing his environment, making him a formidable hunter and combatant. In essence, Battle Beast's power comes from a combination of his superhuman physical attributes, combat mastery, intense battle drive fueled by a blood curse, and his alien feline physiology.
