Maul from his early years has trained in the ways of the dark side. He does not have any memories of his homeworld of Iridonia or of his birth family. He is incapable of normal emotion with the exception of bloodlust and rage. During his training any show of fear is severely punished by Sidious. Also if he even hinted at the thought of mercy he would be rewarded with cruelty. By the time Maul reaches adolescence, his master has forged him into a weapon of pure hatred. Marked by Sith tattoos that cover his entire body, Maul has now the ultimate tool of the dark side. Despite this rather traumatic childhood, Maul adores his Master, and had never once contemplate killing him. Sidious abandons Maul on an isolated Outer Rim world, forcing him to survive alone while being hunted by hordes of assassin droids. After a month's time, his master returns and challenged him to a duel, one which the already severely weakened Maul quickly loses. Sidious then tells Maul that he has failed and is soon to be replaced. Overwhelmed by hatred, Maul nearly defeats his master. When Maul's emotions are finally spent, he prepares to die, yet his master laughs instead. By wanting to kill his own master, Maul has in fact passed the final test. His master proclaims him Darth Maul, Dark Lord of the Sith, and took him to a new home on Coruscant.

Darth Maul is trained by Darth Sidious to be a master of lightsaber combat. Unlike the traditional dueling techniques of most Jedi, Maul combines his swordsmanship with incredible acrobatic and hand-to-hand combat skills, making him a nearly unstoppable dervish of destruction. When fighting multiple opponents, Maul extends the second blade of his double-bladed lightsaber to form a saberstaff. Maul often uses this to catch opponents by surprise, as few are prepared for the extra blade. Maul constructs this weapon himself, using ancient plans stored within one of the Sith Holocrons.

His master gives Maul the funds and schematics he needs and provides him with a secret facility on Coruscant in which to work. There, Maul constructs his signature speeder bike, Bloodfin, and his Dark Eye probe droids. Maul also builds a powerful transport — a Sith Infiltrator called Scimitar, which hosts a cloaking shield generator.

Maul originally goes on countless missions of terror for his master, killing politicians, crime bosses, merchants and warlords. His victims includes Neimoidian Hath Monchar, the Black Sun leader Alexi Garyn, the Nightsister Mighella and all of the Black Sun vigos and their bodyguards. Maul also kills many Jedi, including Barco Trellius, Roro Fergus, Ji-Dis Flar, Darsha Assant and Annon Bondara.

Death

After landing on Naboo he come in contact with two Jedi and the Queen of Naboo. Maul goes straight at the two Jedi, ignoring the queen and allowing her to escape. In a vicious duel Maul fends off both of his Jedi opponents with the help of his double-bladed lightsaber. After separating the Jedi Master from his Padawan, Maul finally succeeds in slaying Jinn. He then challenges Kenobi. The young Padawan, enraged at his master's death, strikes out at Maul with a furious assault. Maul eventually Force-pushes Kenobi into a pit. He taunts the Padawan, who dangles helplessly by a ledge, watching his lightsaber fall down into the abyss. However, Kenobi instantly calms down and connects with the Force. He makes a spectacular leap out of the shaft and Force-guides Jinn's lightsaber into his own hands. Wasting no time in striking as he landed from his jump, Kenobi cuts the astounded Maul in two before he can react. Maul barely has time to grimace as his body tumbles down the shaft in two pieces.

Return

Later an Iridonian sicentist found Maul's body he brought it to his lab on Iridonia and gave Maul kind of robotic legs. Maul then went to Tatooine where he met an aged Watto who Maul killed. Later Maul approuached Owen Lars who with his rifle shot Maul.
