The Penetrative Fist was a skill that allowed Lex to control a large sum of energy and release it while striking an opponent.
However the energy instead of being used to fuel the impact, it would be controlled by Lex and carried into the opponent's internal body that was weaker than the external body to damage the opponent.
Depending on the amount of energy and the strength of the opponent, the skill could instantly kill an opponent after destroying key internal organs and the energy would explode within the body of the opponent.
The sudden surge of energy that couldn't be digested by the opponent, as it was Lex's energy, would attempt to escape from within the opponents body and when it couldn't, it would explode after reacting with the opponents energy.
