A few days ago I was using artificial intelligence to distract myself and it came to mind to answer a concern,how strong the slayer is ? the general idea the slayer is stronger than most vampires.
But there are no official numbers, then use as a reference two episodes where you see what a slayer can do with her strength.
So using artificial intelligence to calculate the Slayer’s strength, it was used as a reference, the episode where Buffy deforms bars from a prison cell and the episode where Buffy momentarily lifts a medium-sized portico.
AI determined the Slayer has enough strength to lift 1 ton.
