I've seen many characters say stuff that never happened in the actual series,the only time Kakashi countered an electrical attack was from Kakazu and looked at what the Jutsu did to his hands.
It completely destroyed his gloves and even made his hand produce steam so it must've caused some pain to his hands.And picture an actual lightning bolt going towards his whole body instead of his hands.../[FONT]You must be registered for see images
No characters have either been lying, or the event in question has never been shown in canon.
