>>6912006>>6912009>>6912574>>6912573The problem with Nihilus, Revan, Star Killer and even Vitiate is that alot of their powers come from video game mechanics.
Which tends to make them OP as fuck (devouring planets, controlling Star Destroyers, being immortal etc). It's hard to distinguish how powerful some of these Siths are because they don't do the same things in their books that they do in video games. If we take into account Power, Achievements and legacy it's hard to argue that Sidious isn't the strongest ever.
Followed by other top Tier Siths like Bane, Plagueis, Krayt, Vader, Cadeus. Mark Aragnos,Ruin, Exar Kun, Ajunta Pall, Naga Sadow, etc
if we're taking Video game Siths into account than yea Nihilus, Star Killer, Revan, Vitiate etc
My personal video game Sith is Tulak Hord
