So Boboiboy is 1.02717281 times stronger.
That's slightly more than a quarter of a percent (A quarter of 1%) as a difference in AP/Striking Strength.
But as mentioned, she has only Building Level Durability against anything that's not Heat or Bullets.
So it becomes a question of is how able to win is she without being too likely to get hit by anything except Fire.
How good at dodging, & is she likely to do it? Can she avoid the Area of Effect (Whatever it is.) of Boboiboy's attacks?
Boboibou leads with Fire? I assume he's usually smart enough to notice after just 1 attack that his opponent is immune before he switches? Or does it take more than 1 attack for him to notice?
Looking at Beatrice's techniques section.
- Dehydration: It is mentioned that fighting in Beatrice's field of flames would kill a normal human through dehydration a hundred times over.
How fast does it kill? Can it kill Boboiboy? Can he die of dehydration?
- Oxygen Deprivation: Beatrice can use nonlethal attacks that use oxygen deprivation to knock out enemies.
Seems to be useless, because Boboiboy has
Self-Sustenance (Type 1; could survive without air in space), unless there's evidence he does need Oxygen to survive. Also, we don't know the timeframe nor range of this, nor how likely she is to use it.
- Analysis Magic: A kind of magic that analyzes the opponent's movements searching for ways to break through the opponent's defense.
Might be relevant.
Without knowing what other types of damage she resists, we can't really assume she does resist them, but it's presumable she'd make more of an effort to dodge attacks evidently not a kind she resists. How evident are the elements in Boboiboy's attacks? Is there any telegraphing to them?
How likely is he to pick up on this implication from Beatrice's behaviour?
Again, for Beatrice to win this match, she has to avoid everything she doesn''t resist (Because it'll hit her as though she's Building Level, & thus, one-shot her.), yet still defeat Boboiboy.
Easier said than done, I imagine.
Presumably, exhausting their stamina so they fall unconscious counts as Incapacitation here, right?
