OG Vader upscales from 82 Zettatons or something like that.
SC scales to someone able to create Planets. With no calc provided, we assume Baseline.
OG Vader therefore has an AP advantage, but not significantly, as he’s not even 2x as strong. SC, however, has the Durability Advantage, as OG Vader needs Force Amplification to get to 5-B Dura.
OG Vader has abilities such as Healing, Barriers, Technokinesis, Mind Manip and more. He can also take harmful energies and disperse them out of his body, assisting him against Lightning attacks and such.
SC Vader has Army-Level Soul Manip, Corruption, BFR, and resistance to Mind Manip and Soul-Edge’s abilities as far as the Profile goes.
So for who has the better ability set... according to the profile, SC Vader seems to have that. SC’s resistance seems Baseline at first glance (Resists Soul Edge, who targets one person?) while OG Vader should have massively above Baseline Mind Manip. While vulnerable to the Corruption and BFR, as well as the Soul Manip, OH Vader has things such as abilities to paralyze SC Vader, Precognition, and Technokinesis (which would probably work on SC Vader? Not sure, is he still a cyborg?). However, I think OG Vader’s far more likely to use his abilities, rather than SC doing so.
OG Vader has Stellar Range with his force powers. Meanwhile, SC has several meters with his force, but Multiversal via Soul Edge. This means SC Vader has the Range Advantage.
OG Vader is rated at Genius Intellect, for a good reason. Having built Droids at an early age, and easily one of the most powerful Sith Lords alive, he’s quite skilled in both Technological and Combat Prowess.
SC Vader is rated at Gifted. He can keep up and defeat Algol, who has a millennia of Combat Experience on him.
SC Vader seems to have the Skill advantage according to what’s on the profiles, but OG Vader is certainly more intelligent.
OG Vader is rated at Very High Stamina. SC Vader is rated at Above Average. While I’m not sure on the reasoning, OH Vader has the Stamina Advantage.
OG Vader is rated at Class G Lifting Strength via The Force, and is Peak Human naturally. SC is simply Class M. Therefore, OG has the LS Advantage.
