Hashmal is an Esper in Final Fantasy XII fought in the Pharos. He is one of the few Espers acquired during the storyline, as he needs to be fought to ascend further into the Pharos. He is also fought in the Zodiac versions' Trial Mode at Stage 49 along with two Reavers. In this battle the player can stealElixir (uncommon) and Ribbon (rare) from him.
Scion set by the gods to wield and manipulate the laws of this world, and with holy power lead mankind to order. Created in opposition to Fandaniel the Protector, scion of light. Desiring to bring order to all things, he joined with Ultima in her battle against the gods. He gave his body to the Thousand-Years War, and when his strength was spent, down into the burning inferno he fell.
Hashmal's attack, Roxxor, is called "Rock You" in the Japanese version, plus some some other translations, such as the Italian translation. This is a nod towards the band Queen; one of game director Yasumi Matsuno's trademarks is to pay homage to the rock band Queen in his works. Rock You has been changed to Roxxor in the English localization, a likely play on internet slang.
