How to make a strong punch like ability?

Basically what the title says, a bit self explanatory but, I'm trying to make a MHA mod or at least I want to do so. I'm trying to do something for Detroit Smash that'd function similar to the charged punch skill from Orca's One Piece and JJK Mod. If anyone could help me work this out I'd be really appreciative! (I'm using 2024.4 MCreator and I do have a discord if you prefer that.)
