Wasn't Ainz considered the strongest
6-C character with speed equalization?
Anyway, Samus leads with Precognition and scanners; the scanners give her complete analysis on not just the biology and technology, but also super natural features. Meaning it gives her info on various hax abilities. Samus also has a distinctive range advantage; being Stellar range. SBA puts them at 4 kilometers apart. Samus can also has her Wave Beam and Ice Beam; Wave Beam bypasses all walls, barriers, and armor and targets lifeforms; can also target Intangible beings of elemental, Immaterial, and Spatial variety. Ice Beam is also extremely potent and can freeze targets to Nigh-
Absolute Zero temperature; she even completely froze the sun with one shot. Samus can also spam her Ice Beam/Wave Beam combination with infinite ammo.
As for resistances, Samus has resistance to most of Ainz elements; especially Fire and Ice. She can resist her own Ice Beam's cold, and withstood the heat from the sun's core. And also given that Samus lived on a 960 G environment since she was 3, gravity manipulation ain't doing much either. Insane gravity on that level should also have a strong correlation to good wind and Earth manipulation; at least the pressure parts of those. I'm not sure if being able to harm characters with Spatial intangibility counts for some form of Spatial manipulation, so whether or not she has resistance to that is speculation. Samus doesn't have phase drift, and she doesn't seem to have a counter to Ainz's time stop. Samus also to Soul manipulation, but Death Manipulation, I know there are different categories, but not sure how Ainz's work. Samus also has resistance to planetary mind manipulation; (Baseline planet levelish according to SD's revision for this key).
Anyway, Samus is far more tactical and ranged, but being more tactical doesn't always help against Ainz level of hax. Ainz does have a 3x stronger power advantage, as well as better hax overall. Reality Warping and Time Manipulation are his trump cards, but that depends on whether or not he uses those in character? Also, how long does Ainz stop time for? It really depends on whether or not he uses those abilities in character. If not, Samus could bombard him with Stellar AoE Ice Beam while Moonwalking at massive speeds to freeze him to Nigh AZ temperatures. But if he does lead with time stop, then Samus may use Electro Barrier to protect herself, but Ainz might be able to hit her enough times to drain all her Aieon while time is stopped. Ainz does have the advantage once Time Stop enables him to get closer.
Won't vote yet, at least until I have more info on what Ainz leads with.
