Rell Seas is an upcoming Roblox game inspired by the One Piece anime. It follows in the footsteps of Blox Fruits and other great One Piece games, though it will be taking everything, and by that, we really mean everything about 1,000 notches up. It will definitely become the new best One Piece game on Roblox, and whether it will become the most popular game ever on the platform is yet to be seen. Here is everything we know about Rell Seas so far.
Rell Seas Will Have the Best Customization of All One Piece Games on Roblox

Blox Fruits and other One Piece games are known to have amazing customization, from outfits and weapons to powers, fruits, facial cosmetics, and other cool things. However, Rell Seas looks like it'll leave them all in the dust in that department.
First off, Rell Seas will have extensive ship customization that matches that of AAA games like Sea of Thieves and Assassin's Creed IV: Black Flag, making it appealing even for players who aren't Roblox enjoyers. Cannons, flags, sails, hull, everything really; you'll be able to change your ship's color and appearance through obtainable cosmetics and make it as swag as shiply possible.

Character customization will also, judging by the sneak peeks on the official Rell Seas Discord server, be amazing, with hundreds if not thousands of cosmetic options for clothes, weapons, and your character's body. There will definitely be people logging into Fashion Seas, eghm... Rell Seas just to farm bosses and get the coolest outfits there are.
Rell Seas' World Will Be Massive and Filled With Content

Maybe the most important thing about Rell Seas is that it will, unlike most new One Piece-themed games on Roblox nowadays, have a massive, unique, and fresh world to explore. It won't be a copy-paste of Blox Fruits like most other games. Instead, it will be a completely new take on the One Piece theme, with dialogues, lore, and locations that are more than just filler text and reused assets. It will be a feast for both PvE and PvP enjoyers, something that most games can't nail these days.
Combat and Systems in Rell Seas Will Be Better Than in Most MMORPGs

Even though the combat basics are reminiscent of other parry-based Roblox games, Rell Seas will spice it up with more weapon and ability choices than any One Piece-themed game so far, more complex melee combat systems, naval warfare (ships go pew pew against other ships?), and other various improvements.
The combat balancing showcased in the sneak peeks is also impressive. There is a very high chance that it won't be a fiesta with spammable guard-break AoE moves on the most OP fruits and weapons. Instead, it will be a challenging and rewarding experience at every stage of progression, regardless of your skill level and current loadout.
What Else You Can Expect From Rell Seas
In the Rell Seas' latest trailer, we can also see promises of underwater combat, unique bosses and monsters, all the customization and combat features we outlined above, and also some of the best graphics we've seen in a One Piece-themed Roblox game so far.
When Will Rell Seas Release?
The Rell Seas developers haven't specified the release date yet, but in the comments of the above-linked trailer, they said that the game will definitely come out in 2025. The best way to stay up-to-date on their progress is to join the Rell Seas Discord server and the Rell Seas Roblox group.
