Also, I had a thought.
So, we rate all the Extra Playble characters as resisting BB's stuff because "(After obtaining the power of the Root of the Beginning,
BB, who is able to manipulate space-time, causality, probability, information, gravity, life, death, minds, senses, powers, and souls through her usage of Potnia Theron, was unable to affect No Name due to being opposed by a power of equal potency)"
And hear me out here...
If they resist all her stuff due to having power of equal potency...
then wouldn't she also be able to resist that stuff via having the power that Roof of the Beginning is equal to?
