How DeathBattle Calculated Luffy’s Speed | Sanji VS Rock Lee (DeathBattle/One Piece Analysis)

One of the things that I dislike most, about Deathbattle, is when they don’t fully explain or show how they found a feat. Some of these feats are simple and others are complex, but I am the kind of person who wants details no matter how simple. So, in this first episode, of this series that might not be a series, we are going to research and unearth how DeathBattle, in Sanji Vs Rock Lee, calculated that Luffy could move at 13 times the speed of light.
