Contrary to what seems to be the popular opinion, I quite like the idea. Fair play, Maul's brother showing up out of nowhere is a bit convoluted, but the idea that there is a tribe of Zabrak warriors all in the same vein of Maul makes sense to me. We know that Sidious never intended to keep Maul around forever and only needed him for the first stages of his galactic plan (after all, he couldn't have used Maul in the same way he used Dooku to coerce entire systems into leaving the Republic) so all he needed was someone he could mould into the ultimate warrior - and if you're going to create the ultimate warrior, you might as well start by taking a child from a tribe/group/society of known "ultimate warrior" types. To me, Sidious knowing where to go to find his 'hand of doom'-style apprentice makes more sense than him just stumbling across a baby Maul one day. If Savage actually is Maul's brother (though as far as I know, it was only ever officially stated in the trailers and clips that he is 'the fiercest of his kind') then I'm sure the TCW will give him some unique characteristics - after all, they've made clear that they don't want viewers to confuse him with Maul. The likely changes in personality I would predict would be either he is significantly less obedient and more defiant than Maul - as Dooku would never have the grip of loyalty over him in the same way Sidious did over Maul - and/or be shown to be a lot smarter/cunning. As for his name - it's not very original, granted, but I don't really have a problem with it. It's no worse than Grievous, the Mon Calamari, inSidious, inVader, Cad Bane, Lobot, "Newt" Gunray and, of course, Maul.
