I wonder what is the normal way to get into CP0, because I have a feeling the former CP9 members blackmailed their way.
Ok my dumb ass just googled how to join cp0, wow
Since people in the manga (in Dressrosa, Nico Robin and also Law) know about cp0 and they aren't a secret organization like cp9 was, it's possible that we already saw other cp0 members before in the story and they are appearing out of sudden as cp0 members.
Fact is that cp0 is the strongest intelligence organization among cipherpol, they work directly under the command of the World Nobels and the members were probably either trained their whole life just for the aim of being a part of cp0 OR had to work their whole life in different positions for the WG to prove they are good enough to join?
I can also think of other characters being in cp0 such as people who work for the marine in high positions or so (explained later).
That makes me question why Lucci and Kaku are even allowed to work for the World Nobels but maybe the WG/WN were just like "ok those guys were super strong though so let's invite them to our cp0 group 🌸💫🧚🏼♀️🌹"
No honestly, I have no fckn idea, haha. We were introduced to Stussy when she was undercover but already as a cp0 agent, so Oda gave us no hint how she joined them. But I'm pretty sure he will. He already did when it comes to cp9 and since 1/3 of the fandom is freaking out cause leopard and giraffe husbando are back, there are even more questions.
I'd like to add that they are called "intelligence organization" and I read that " "Aigis" in "Cipher Pol Aigis Zero" may be derived from the Aegis, a mythological shield associated with Zeus and Athena shown as a short goatskin cloak. Athena's aegis is usually shown with a border of snakes and with the head of Medusa in the center. It is more an emblem of protection and power than an actual military shield."
So I don't think it's just about being incredibly strong (what they are) but have way more abilities not only measured by physical strength (so in my eyes a marine member could join too). Or cp0 is really about whole-life-trained people and my mind is just messing with me.
I need answers too 🤷♀️
