GIVE ME THEORIES ON POCHITAS/CHAINSAW DEVILS STRENGTH!!!

I remember seeing somewhere that Pochita was so feared cause they used to use chainsaws during childbirth, but idk I feel like there's better.

I'm more talking part 1 Pochita, before there were chainsaw heads all over the place contributing to his strength.

Pls let me know how you guys think Pochita is so strong and feared.
