Not good enough!
As he is paralyzed and hears the lightning under your feet he recognizes the arrow step technique, having faced it many times. As you come towards him he releases a full body lightning current that reaches to the edge of short range and catches you, paralyzing you as you are unable to stop while breaking out of his paralysis.
(Raiton: Chidori Nagashi) - Lightning Release: One Thousand Birds Current
Rank: A
Type: Offense/Defence
Range: Short - Mid
Chakra Cost: 30
Damage Points: 60
Description: This jutsu allows the user to generate non-focused electrically charged chakra from their body. Because the electricity isn't focused, it doesn't kill on contact, instead it only paralyzes. The lightning can be channelled through metal objects, as well as spread out into the air or ground.
However even though your paralyzed your speed would keep you moving towards Broly, but at a somewhat slowed pace due to your lightning arrow step being canceled from your chakra being disrupted a bit from the nagashi. Even if you were going the same speed, as soon as the nagashi is released he surrounds himself with an electric field that hits you and explodes, blowing you backwards, giving you damage, and stunning you. Its possible to do this so fast due to not switching affinities, being a lightning specialist, and the low amount of chakra needed to be built.
