User blog comment:Kaido King of the Beasts/A Rival for Luffy/@comment-27158424-20160118224702

How about Eustass Kid? He's one of the deadliest Supernovas out there (besides from Luffy and Law), he formed an alliance with two other deadly Supernovas (Basil Hawkins and Scratchmen Apoo), and they're targeting Shanks. Seems like material fit for a rival!
