Khameir opress is actually not his name. The previous answer submitted probablyvthough that because Savage Opress often refers to Maul as "brother" but this is not the case. Oppress means that they are both members of the nightbrothers. Maul's real name is Khameir Sarin.
There is much speculation as to Darth Maul's real name but common consensus seems to hold that his birth name was either Khameir Sarin or Manuel Gonzalez . Most sources lean toward the former .
by far, Darth mauls.
I think Palpatine
Khameir Sarin
If you're referring to Darth Sidious, his real name is Palpatine
If you watch the 3rd episode of Star Wars, you will find out Anikin Skywalker turned into Darth Vader. Darth Vader and Anikin Skywalker are the same people.
The cheat code for Savage Opress is MELL07
there are different kinds of light sabers most are custom made like Darth mauls is double sided and count dookus is curved at the end
Darth Plagueis' master's name was the Sith Lord Darth Tenebrous.
Darth Tyranus's master was not Darth Caedus. Caedus was way after Dooku had died. Darth Tyranus's real master was actually Darth Sidious (Chancellor Palpatine)
I am not sure if you will ever know about Darth Mauls' past, but he certainly killed aliens, Jedi, and droids. As far as I know, he was a hard cold killer so he may have even killed Sith. But if anyone knows the REAL past of Darth Maul, and not some type of dumb made up story, just edit this answer and type his real past. All I know is that he was sort of an assassin sent my Sideous or Dooko, but anyway, he he has a battle on Tatoonie (I believe) and kills Qui-Gon Jinn but Kenobi cuts Maul and half and is victorious.
If it the force was real than Darth Vader definitely.
