Lothar was "Prince of the Seven Nations", a mighty federation of jungle tribes; but forbore to become king and instead followed Mandrake on his world travels. Lothar is Mandrake's best friend and crimefighting companion. Lothar is often referred to as "the strongest man in the world", with the exception of Hojo — Mandrake's chef and secret chief of Inter Intel. Lothar is invulnerable to any weapon forged by man, impervious to heat, cold and possesses the stamina of a thousand men. He also cannot be harmed by magic directly (fire bolts, force bolts, spell incantations).
