I was wondering if there is a scientific way to explain how my characters are capable of extreme levels of strength when engaging in combat.
My characters are biological but have implants that allow them to create energy attacks, such as electricity, lasers, plasma and chemical attacks of poison, using gas and a spark for fire as well as other attacks yet to be designed.
I contemplated giving them metal or nano material bodies to give them extreme strength but I would prefer to keep them as biological as possible but with a lot of help from individual implants.
Is there a scientific explanation for extreme strength using implants but in the form of a strong force when needed, maybe by means of creating an energy field or something similar, that is activated the moment they strike or are struck?
My story in general is near future technology but I don't mind certain aspects being more in the realm of science fiction.
Edit. to clarify i am talking about a repelling force from their fists and feet when they attack to hit the opponent harder and a force like a shield for defence which could be the same repelling force.
