How to create One for all smash?

Maybe one of you was watching Boku no hero academia, so do you know how to create the effect of hitting one for all or the effect of explosions? Namely, what would the effect appear when pointing to the specified point, or near the player. Perhaps you know some guides on YouTube. Please help. Thank you in advance

I think you are trying to create an explosion when a player plays an animation, that being the punch. You can just use Instance.new to create a force field, to not kill the player, then set the forcefield's visibility to false as forcefields are kinda like gui's in a sense. Then we make a instance creating an explosion on the players hand.
