While I've seen him dodge attacks, I have yet to see a single attack going through Laxus' body. I have no idea what the person who wrote that onto the wiki was talking about.

In my opinion it's far more likely that he moves faster than we can see and the visible effect is just something that actually trails behind him, revealing were he was, not were he currently is.

After all we only ever see him "as lightning" while moving very fast, never when he's staying in place.
