How Mr. 7 and the mysterious organization teased in Netflix's new live-action 'One Piece' may factor into season 2

• Netflix's live-action "One Piece" adaptation adapts the first saga of Eiichiro Oda's manga.
• However, it briefly teases a potential future story — with a character named Mr. 7.

Netflix's live-action "One Piece" adaptation covers, for the most part, the first 95 chapters of Eiichiro Oda's manga of the same name.

The series follows Monkey D. Luffy, the captain of the Straw Hats, a young man with rubber-like powers who aspires to become King of the Pirates. He begins his journey in the East Blue, one of the world's oceans, gathering crew members to sail on the Grand Line — the most treacherous stretch of ocean, and surely the path to the famed treasure of the former Pirate King, the One Piece.

While the show is mostly accessible to viewers who aren't familiar with the source material, there are a couple teases to future events that might be a bit confusing to non-manga readers.

One of those happens in episode one, when a man named Mr. 7 invites Roronoa Zoro to join an organization called Baroque Works. Manga readers and anime watchers will be familiar with the name — but if you're confused, here's a brief rundown.

Warning: Major spoilers ahead for episode one of Netflix's "One Piece," and the Arabasta Saga of the "One Piece" anime and manga.

Before he became the swordsman of the Straw Hats, Roronoa Zoro was a famed bounty hunter. In the manga, readers first meet him while he's being held captive by Captain Morgan at a Marine base. In the show, however, we encounter him on Sixis Island, located in the East Blue, lighting flames for a lost friend at a shrine.

There, a man named Mr. 7 invites Zoro to join an organization known as Baroque Works. Zoro quickly turns him down — but not without a quip about how he'd at least want to be number one.

"To turn down Baroque Works is to turn down your life," Mr. 7 tells Zoro.

"If they were that serious, they should've sent someone better than number seven," Zoro replies. They fight, and Zoro slashes him in half.

While Baroque Works isn't mentioned again for the rest of the season, Mr. 7's appearance is part of Zoro's backstory in the manga — and it's a huge tease for a potential season two of the show.

Who is Baroque Works?

In the manga, Baroque Works is a secret society of bounty hunters led by a mysterious boss whose identity isn't even known to his subordinates. The organization, and its leader, are the main antagonists of the Arabasta Saga, which is where the live-action show would likely pick up if it's renewed for a second season, given where the season one finale leaves off.

During the Straw Hats' first stop on the Grand Line at the town Whisky Peak in the manga, Zoro takes down a horde of Baroque Works agents, revealing that he knows about the organization because they once tried to recruit him.

Eventually, Baroque Works turns out to be a front for a larger purpose. The group's mysterious leader is actually Crocodile, one of the seven warlords of the sea — powerful pirates aligned with the World Government. Its true purpose is the conquest of the desert nation of Arabasta. Luffy and his crew align themselves with the nation's princess, and end up fighting Crocodile and Baroque Works' top agents.

Who is Mr. 7?

While one man with the Mr. 7 title appears in the manga during the Arabasta Saga, Zoro's said to have defeated the original Mr. 7 years ago. The story in the manga is pretty similar to what's shown in episode one of the Netflix show.

In chapter 190 of the manga, top Baroque Works agent Mr. 1 reveals that he knew that Zoro had turned down an offer to join the organization in the past, killing the previous Mr. 7 in the process somewhere in the East Blue. Zoro replies that he told the former Mr. 7 that he would join the organization if he could be the boss.

"Instead of agreeing to my demand he attacked me, so I dealt with him," Zoro explains.

How will this play out in 'One Piece' season 2?

Right now, Netflix hasn't yet announced that it's picked up '"One Piece" for a second season. However, between the Mr. 7 appearance (and the character tease in the season finale), it seems likely that the show will indeed adapt the Arabasta Saga next.

That would mean we'd see Luffy and his crew enter the Grand Line, embarking on a quest to save Arabasta from Crocodile's conquest. If that's the case, you'll see much more out of Baroque Works: The Straw Hats will have to fight their way through the organization in order to defeat Crocodile. Expect some killer fights, colorful characters, and lots of sand.
