The power mace was a single-handed weapon characterized by a substantial, spherical head designed for striking, connected to a slender shaft. This weapon incorporated an integrated power source that delivered an electrical shock upon successful impact. Not long after the Yavin Battle, the Human smuggler, known as Han Solo, employed a power mace during the Big Game, a gladiatorial contest held on the Wheel orbital station. Despite its presence, the mace proved ineffective against Solo's four-limbed adversary, but the smuggler was still victorious against their foe.
The power mace was a close combat weapon featuring a slender handle and a large, spherical, spiked head, approximately the size of a Human's head. This weapon was equipped with an electrical charge, causing it to emit a yellow radiance and inflict additional damage upon a successful strike. The wielder would grip the mace in one hand, attempting to strike opponents with its spiked head. At least one version of this weapon possessed a gray coloration.
During a visit to the Wheel orbital station amidst the Galactic Civil War, the Human smuggler Han Solo participated in the Big Game, a gladiatorial competition, seeking to secure a cash prize to settle his debts with the station's administration. When Solo refused to disclose his preferred melee weapon to an official of the game, as a protest against suspected manipulation of the game's rankings, he was assigned a power mace and a power shield for his initial match.
Solo's opponent was a massive member of the Ultaarian Greenback race who carried venomous dagger thorns. The power mace seemed unable to harm the large opponent, and shattered upon impacting the creature's back. Subsequently, Solo used the energy shield to trip the four-armed combatant, leading the hulking gladiator to fall onto a dagger thorn and perish.
A power mace is depicted in Star Wars (1977) 20, a publication of Marvel Comics' Star Wars comic series released on February 1st, 1979. The issue was authored by Archie Goodwin, with illustrations by Carmine Infantino and Bob Wiacek.
