Alright so this achievement is basically to get 100% Karma with EVERY person/faction in the Karma section of the game. Below I will be listing every Karma faction and each step you have to take to increase them. I will go down the line from Top to Bottom, Left to Right in the Karma tab. Most of these are extremely easy and don't require much planning; however, certain ones do require a little bit of grinding if you want to get them out of the way ASAP. This achievement is a lot easier than it seems due to different factions needing the same requirements in some situations.
MAJOR NOTE: EVEN IF YOU DON'T HAVE THE FACTION UNLOCKED IN THE KARMA TAB YET YOU CAN STILL WORK ON THE KARMA REQUIREMENTS MAKING LATE GAME KARMA FACTIONS DONE ALMOST AS SOON AS YOU GET THEMStraw Hat PiratesThe Straw Hat Pirates Karma Faction will most likely be the first one you 100% or one of the first. All you have to do is complete side missions and they are all available by Chapter 7 or Chapter 8. If you're like me and tend to do everything optional before doing all mandatory missions, this will be your first 100% and will also earn you the achievement Join My Crew!

JeanneJeanne is mostly just more side missions and main missions but she won't be able to be 100% till after starting Chapter 14 as her last Side Mission requirement is in Chapter 14.

-Travel a distance of 20,000 across the island
-I earned the achievement for travelling 50,000 around the island before even starting anything with Karma so you don't really have to worry about this one
IsaacIsaac is a lot more grindy but not too bad.
-Complete Side Mission: Unchanging Sea
-Complete Side Mission: Sea Changer
-Defeat 100 Sailors
-Defeat 250 Sailors
-Defeat 500 Sailors
- Sailors are more common than pirates. If you go to any of the Naval bases or any Navy controlled area you'll find a group of them. Since you have to defeat 1,000 enemies anyway this will come naturally.
-Defeat 50 Pirates
-Defeat 125 Pirates
-Defeat 250 Pirates
- Another requirement that will come naturally. Amber Harbor, Ruby Village, Crystal Canyon, and pretty much anywhere around the water you'll be able to find Pirates.
Pro-NavyThe Pro-Navy Faction is really easy and another one that won't give you any trouble.
-Complete Side Mission: Nostalgic Place
-Complete Side Mission: Consideration
-Complete Side Mission: True Treasure
-Complete Side Mission: Divided We Stand
-Defeat 125 Pirates
- See Isaac above
-Keep a Gum Gum Rocket going for 10 seconds
- I saw a lot of people say go for this in Steel City. I'm here to tell you DO NOT DO THAT as the snipers there are God-like and will hit you in the face without their detection even being red. The best place to go for this is right outside Ruby Village next to the Prison Tower - Tourmaline as there is a forest there that allows you to just Rocket all over the place. You'll get the credit as you land and if you haven't done it yet you'll also get the Woohoo! Achievement. In the skills section under Explore, make sure to purchase the Gum Gum Rocket skill as well as the Gum Gum Rocket Flight Increase skill.
Anti-NavyThe Anti-Navy is pretty similar to Pro-Navy as they require the same side missions but the last 2 are slightly different.
-Complete Side Mission: Nostalgic Place
-Complete Side Mission: Consideration
-Complete Side Mission: True Treasure
-Complete Side Mission: Divided We Stand
-Defeat 250 Sailors
- See Isaac above
-Fly with Gum Gum Rocket for 200 seconds in total
- This is cumulative. Just use the Gum Gum Rocket whenever you get the chance and this will come with time. Considering you have to use Gum Gum Rocket for 30 minutes in total for the Fly Away Achievement this is cake.
SaboSabo doesn't become available till Chapter 9. A few of his requirements are also the same as others so it'll be killing multiple birds with one stone.
-Complete Side Mission: Prison Tower Smuggling
-Complete Side Mission: Within The Sea Prison
-Complete Side Mission: Bond of Brothers
-Defeat 15 CP Agents
-Defeat 40 CP Agents
-Defeat 75 CP Agents
- There are a few missions that have you defeat CP agents. Steel City also has a few roaming around but there is a dedicated spawn in the Naval Base next to Steel City. Looking at the group of 4 boats there are 3 CP agents that spawn on the first boat to the right. Just use a Takedown or beat them the old fashion way, Fast Travel to somewhere far away so it registers the respawn, Fast Travel back and rinse and repeat
-Hit Kizaru with Gum Gum Red Hawk
-Hit Kizaru with Gum Gum Eagle Storm
-Hit Kizaru with Gum Gum Elephant Gatling Gun
- Before you can do these you need to purchase Gum Gum Elephant Gatling Gun and Gum Gum Eagle Storm from the Battle section of the Skill tree. I recommend only getting the base versions and not any damage boosts until these are all done. You start with Gum Gum Red Hawk already learned. To use these moves you have to build your tension meter. Red Hawk takes one full bar, Eagle Storm takes 2, and Elephant Gatling Gun takes 3. You fight bosses a couple times throughout the game if you do the Side Missions. You only have to do each fight twice to get them all with the exception of Smoker but the amount of times you fight each boss is more than enough, and then you can refight bosses later in the game. I highly recommend to build your meter and then hit the boss with Gum Gum Red Hawk and then Gum Gum Eagle Storm, and in a later fight hit them with Gum Gum Elephant Gatling Gun. You can potentially do all 3 in one fight if it's a boss fight that has 2 bosses where you can build your tension meter if you've already done the special moves on one of the bosses.
-Mark 70 Enemies
- You mark enemies just by looking at them. You'll most likely get this on accident but a little arrow will appear over their head when they're marked. The tutorial for this is done right before reaching Sapphire Town.
-Use Takedowns to Defeat Enemies 30 times
- Initiate a takedown on an enemy when you sneak up on them from behind. The A.I. in this game isn't all that great and you can pretty much get up on them from any angle except from right in front. Just get behind them and press X. You have to do 100 Takedowns for the Takedown Legend achievement
Trafalgar Law-Complete Side Mission: Mystery Of The Sky Islands
- Supposedly this mission appears when Law's Karma is at 50%; however, I did not get this to appear until I had finished all of Law's other requirements. The mission will spawn at the Thousand Sunny on the dock. This mission you'll have to visit 3 areas and defeat CP agents and then you'll be able to head up to the Sky Islands, netting you the I Wanna Go To The Sky Islands achievement.
-Defeat 8 Navy Leaders
-Defeat 20 Navy Leaders
-Defeat 40 Navy Leaders
- Much like with the CP agents, we're going back to the Naval Base next to Steel City. Looking at the ships, the 2 ships on the left side each have a Navy Leader. Just take them out, warp far away, warp back and they will respawn each time.
-Defeat 5 Pacifistas
-Defeat 10 Pacifistas
-Defeat 20 Pacifistas
- Just like the Navy Leaders and CP agents. At the Naval Base next to Steel City, looking at the ships, the last one on the right has 2 Pacifistas every time you warp there.
-Perform a takedown on Smoker
- In order to perform a takedown on Smoker, you'll have to stun him. The easiest way to stun him is to perform Conqueror's Haki on him which takes a full tension bar and can be bought in the Parameters section of the Skill tree. Once stunned you can just press X to perform the takedown. You could also use range attacks on him to stun him but it's not always reliable.
SakazukiSakazuki will be the last one you unlock and it won't be until Chapter 15.
-Complete Side Mission: The Navy Fleet
- This mission is a Hidden Mission. This means it will not appear as a Blue ! on the map and can ONLY be done during Chapter 15 and Chapter 16. It is located in the south end of Sapphire Town by the docks. If you're looking at the map it's going to be the house closest to the water on the right side of the fast travel point to Sapphire Town. Here is a link to where it's actually located and how to start it:
(Video credit goes to WeDeserveBetter on YouTube)
-Hit Sakazuki with Gum Gum Red Hawk
-Hit Sakazuki with Gum Gum Eagle Storm
-Hit Sakazuki with Gum Gum Elephant Gatling Gun
- See Sabo above (Fighting Sakazuki/Akainu is a scripted fight and you should have no trouble with doing all 3 special moves on him in the fight as he has more than enough health. I suggest building up your meter before the fight even starts with the enemies down below so when it starts you can get one or two moves off. This will be your last 100% Karma faction)
KizaruBy the time you unlock Kizaru as a Karma section you should have almost everything done except for one.

Well that is everything listed that you need to do in order to get 100% Karma with every faction and obtain Pirate Rank 100 in One Piece World Seeker. All in all this achievement is very simple and doesn't require a ton of effort due to certain enemies having set spawns. As for the robots you fight enough through the story and side missions to be able to get all of those requirements as well, with a ton of robots to fight near the end of the game. Hope this helped and if you vote negative please let me know why so I can edit it.
