Author:ok so basically I did my own interpretation of why those with d in their name were so feared and we're always such a big trouble this is basically like a world building lore type chapter so you can understand what the story is about so before you start reading the actual chapters you might want to read this first so you can understand what the MC's main goal is.
950 years ago the D. Clan was formed 3 sisters and 1 brother the leaders of the d. Clan was the most powerful of the clan spread the world of One Piece the D. clan was composed of humans with this unique thing known as conquerors haki they were in total 3 types of haki armament observation and the newly discovered one during this era conquerors the ability to project the users will across a certain area knocking out anyone who is weaker than the user or has weaker willpower then the caster of conquerors Haki.
Multiple pure bloodied members of the D Clan started falling in love with regular women and men causing the bloodline to become separated between pure bloods and sub bloods even still being half of a D Clan member still make the children ferocious they were naturals and observation and armament haki but they only had a 50 to 35 to 25% chance to have conquerors haki depending on how impure their D. Clan genetics were.
The D Clan was in bursted with laughter in joy as the Queens had sons of their own and when the Royal bloodline and the D. clan bloodline in general started to grow and grow the other clans got jealous the only ones who aren't jealous of the D.

which worked extremely well for the secondary Branch D and x members as due to their mixed DNA the main point of D. clan involvement was nearly impossible to pinpoint as the genetics of both the D and X clans spread across the globe for the next hundreds of years there was always somebody with a D or an X in their name that was either a figure of power or someone who Rose to do the unthinkable or defeated the undefeatable and when the Marines first formed and pirates were less of a common thing the D and X clans were always among The bounty wanted posters.
