So few years back, Togashi gave us the tree of known characters and how they became great, excellent, Genius and ultimate.
After looking at it little bit more, I was strongly surprised and everything I say so far, feel free to correct me
Originally, I thought proficienci was about their power, but I was corrected quickly by proficiency of the character being how much of their potencial they are using. Which is why I asume Komugi is above Gon or Abengane being above Genthru or Knuckle. (which also made me realise just how powerful Razor or Gon could have gotten)
Another thing that surprised was that there is no Ultimate one for Manipulators and Specialist. (Yes, Specialist have Alluka as ultimate. But Alluka is pretty much an anomaly.) Chrollo still capable of becoming even more.
Same for Illumi. Which really surprises me. Illumi was capable to create needle so well hidden and so strong, it influenced Killua for years. His Needles allow him to change his appereance and control multiple people at the same time. (also, I was really surprised that Shalnark wasn't mentioned in it, but I asume he will be at least on same level as Illumi, meaning Genius.)
I am not caught up with Manga, so if there are new characters, who are ultimate Manipulator or another Ultimate Specialist, let me know. I am curious and might finally push me to catch up.
Just a side note, after seeing Abengane being a conjurer, I was really surprised. I thought his ability was specialist, since it could 'defuse' another nen ability. But I guess it really shows what kind of power it really is and how he honed it.
Any thoughts about stuff I talked about here? Feel free to correct me and also let me know about your favourite character and what lvl of proficiency do you think they are, (for example Killua. I assume he will be still great, since his potencial was always around same with Gon's. Although Thundergod might put him on Excellent lvl)
