Okay, let's go-
Raw Power/Toughness: Taiga's ">>>~13.7 billion" and Doc's ">>>several billion" are surprisingly quite close. Taiga's got the advantage, but not by a lot.
Intelligence: Doc, for sure. Taiga, even wielding the soul of the God of Creation, is still a normal-ish person for all intents and purposes- Doc's a walking cluster of supercomputers that have been processing data non-stop since the dawn of time, effectively.
Physical Strength: Goes to...
Doc easily, somehow, ...this ever matters, for whatever reason, I suppose.
Experience: Doc, of course.
Speed: Equalized. Thank goodness, too, or it's Immeasurable vs. not Immeasurable, which uh, lol.
Stamina: Goes to Taiga by a
lot. She'll be fighting infinitely, at peak general capacity even after Doc's admittedly impressive stamina's run out, if he lets the battle drag on for a millennia too long.
The Juicy Stuff: Hoo boy.
Taiga
- Attacks: Wide Array of Elemental Magicks, Swordmaster, Glyphs/Zone Control, Soul Absorption, Summoning, Stat Amp., Transmutation, Time Slow/Speed/Stop, Fear/Pain/Concept/Spatial Manipulation, BFR
- Defenses: Possession, Power Null and Mimic, Absolute Zero, Reality Warping, Existence Erasure, Petrification, Precognition, and Soul/Illusion/Time/Mind/Matter/Fear/Pain/Heat/Biological/Poison/Empathic/Fate/Death Manipulation. Oh, and also basically everything else that'd target her directly (anything that'd be a "Status Effect".) All on a level apt to block things considerably more magically powerful than her, that only died to her use of the Creation Energy (arguably on a 5-D level then, even.)
- Passive: Freezing Aura, Abstract Existence, Instinctive Reaction, Precognition
Doc Scratch
- Attacks: Instant Death with Deudly Magnum, Shapechanging weapon, Power Null, Brainwashing, Conceptual Curses, general Reality Warping, Space/Time/Concept/Information/Law/Mathematics Manipulation, BFR
- Defenses: Absolute Zero, Mind/Space/Time Manipulation, Infinite Lives via Altgeddon, Godmodding, Wields the Narrative as a Plot-based ultra-defense
- Passive: Hyper-mobility via the Fez + the vast array of different powers for specifically this, Acausality, Precognition
Honestly, the way I see this:
Before the fight starts, Doc's frozen solid. Well, crap. Except infinite accounts and Absolute Zero resist kick in, and because Taiga's range doesn't extend to an infinite multiverse anyhow he's still in the game, no harm no foul. Which is nice.
Taiga is clearly physically superior, especially as it pertains to stamina, and has more obvious/clear Stat Amp. showings to exacerbate this advantage that she tends to spam a lot in character. Doc, however, is mentally far and above Taiga: a newborn baby would have the same amount of luck with him here trying to outwit Einstein as Taiga would this godmodder. If he realizes that basically all of his powers are going to bounce off her, he'll start piecing together a battle plan a lot faster than she will once she realizes that, as long as he wields the Narrative (which she can perceive), she's not getting anywhere close to touching him.
That said, Taiga also has a much more glaring Achilles Heel to exploit if she gets to that point: namely, that the Godmodder has no meaningful resistance to Soul or Lifeforce Manipulation/Absorption listed on his profile, and since Taiga can run all of her shenanigans on the level of her target as an idea/concept (plus is not subject to Precognition) she could in theory pierce Doc's defenses to either potentially end him outright, or to at least weaken/distract him enough to use the chance to disarm him of the Narrative. I would say that he can do the same once he figures out that Time Travel is a thing he can just kinda win instantly with, but Taiga having Precog. and Instinctive Reaction stacked up like that means she probably just pulls her own time tomfoolery to freeze it forever, so she doesn't get killed in the past when she was an 8-C or something.
It really just seems to be an instance of Taiga having to stay on her toes and let Precog./Definitely not Ultra Instinct take care of defense against whatever he might throw until she figures out the answer to the puzzle, and hope Doc's immense intelligence/experience advantage doesn't catch on before its too late and he Godmods a defense against the attack just witnessed into being.
I can see a couple arguments for Doc? Namely, that he can either set up defenses/use his mobility to recover stamina and render that drawback meaningless, slowly stockpiling immunities to Taiga's various Win Conditions until either he forces an Incon., or the sheer
overwhelming power of his silly brainwashing feat being enough to punch through Taiga's mind control resistance. That said, with Taiga having a bit of a raw power advantage, I see it to be slightly more likely that she punches through his defenses before that happens.
So... wow. I guess I vote Taiga, High-Diff., for now at least; kinda on the verge of switching to Doc just because of the absolutely silly magnitude of a couple of his hax feats, though.
