So we all know that Zangetsu said that yelling out the name of the move makes it stronger when Ichigo was learning Bankai. The question is there any evidence of that concept appliying to other characters?
Only other example I can think of is during Charlotte Chuhlhourne fight with Yumichika where he claims that bitting his tongue halved the power of his thunder punch. But I honestly think that was a joke so i would want hear your guy's thought on this concept.
Edit: anything other than kido perhaps
