Most people who want "something like Blox Fruits" are not missing the whole game — they are missing one thread of it. Blox Fruits bundles a long level grind across three seas, a hunt for rare fruit powers, a world where any trip can turn into a fight with another player, and anime-style combat holding it all together. Each of those threads leads somewhere different, so here is where each one goes.
For the same pirate formula
If you want all of it at once — fruits, swords, islands, bosses — stay in the One Piece family. King Legacy is the closest sibling: the same eat-a-fruit, level-up, sail-on loop in a tighter package that is easier to get your bearings in, with less sprawl than Blox Fruits' three seas. Grand Piece Online pulls the other direction: slower and stricter, built around long sails, rare drops, and boss fights that feel earned rather than farmed. Pick King Legacy to keep your current pace, GPO to trade speed for weight.
For the fruit lottery
If the real pull is landing something rare and building your character around it, Shindo Life runs that same engine with ninjas instead of pirates: you spin for bloodlines the way you hunt fruits, and one lucky spin changes how your whole character plays. Anime Fighters Simulator reduces the idea to pure collection — summon fighters, watch the numbers climb, no combat skill required. And Sol's RNG is the lottery with everything else removed: no map, no bosses, just the roll and the odds. Half of the fruit game in Blox Fruits is trading, and if you like knowing what a fruit is worth before you deal, BloxTradeView publishes fruit trade values.
For the long grind
Maybe what you would miss is the slow build: hours in, stats up, a little stronger every session. Arcane Odyssey is the pick if you like the sailing as much as the fighting — an original open-sea RPG where you build a magic user instead of a fruit eater, with more story and a deeper build system than Blox Fruits, though the anime flavor is gone. Dungeon Quest drops the open world entirely and keeps only the treadmill: run dungeons with a group, take better gear, push a harder difficulty, repeat. More loot, no sea.
For open-world PvP
If your favorite part is that other players are always a live threat, two games raise those stakes. Type Soul swaps One Piece for Bleach: pick a faction, grind a deep progression, and fight in a world where the factions are built to collide. It is heavier than Blox Fruits and makes fewer concessions to new players. Deepwoken is the far end of the lane — an open world where death is permanent, so every fight you take actually costs something. That is more tension than Blox Fruits ever asks you to carry, and it is exactly why its players stay.
For the combat alone
Maybe you never cared about the levels and just like anime fights. The Strongest Battlegrounds strips out every RPG system and leaves the brawl: pick a moveset, learn its strings, and win on execution instead of stats. Jujutsu Shenanigans does the same with Jujutsu Kaisen flavor and ragdoll physics that turn every knockdown into a small event. Neither one gives you anything to grind, which is either the problem or the point.
How to pick
Name the thread you would actually miss. If it is the whole pirate package, King Legacy is the fastest transfer. If it is the fruit lottery, spin bloodlines in Shindo Life. If it is the grind, Arcane Odyssey; the open-world PvP, Type Soul; the fights themselves, The Strongest Battlegrounds. Every game above lists similar titles on its page, so one good pick leads to the next. For the wider field, the RPG & Adventure and Fighting & PvP genre pages cover both halves of what Blox Fruits is, or you can start from the full directory. If the anime flavor is the part you care about, The best anime games on Roblox sorts that field by lane, and Find games like your favorites shows how to keep following the thread from any game you land on.
