Who's who was 38 years old during the events of Wanokuni. Thirteen years ago, he was 25. He called himself a genius equal to Lucci, so personally, I think his 2300 power is quite justified.
After all, 11 years later, during the events at Enis Lobby, 23-year-old Kaku had a strength of 2200. Therefore, I think that 25-year-old Who's who was full of energy and was not inferior to 23-year-old Kaku.
As for Rob Lucci, he was 30 years old. Thirteen years ago, he was 17, a year younger than the main character, Luffy.
However, 11 years later, during the events at Ennis Lobby, 28-year-old Rob Lucci had a strength of 4000 units, which caused Jabra to be delighted:
- Such power! I've never heard of anything like it!
So I guess Lucci's power at that moment was around 2300.
The current protagonist is comparable in strength to Rob Lucci in 11 years.
To explain briefly, in the original plot of the events at Ennis Lobby, 28-year-old Rob Lucci possessed an incredible 4000 units of strength. Combined with the Zoan Devil Fruit, which greatly enhanced his physical abilities, his strength surpassed the so-called "supernova pirates" of the Worst Generation.
Without the use of Haki, he was able to defeat the rubber Luffy through physical training alone, severely injuring him and causing him to bleed. If Luffy, as the protagonist, had not unlocked the "gear 2" and received the bonus from the protagonist's aura, he would not have been able to defeat Lucci.
The main character of this book, Baptiste Sonic, has 4500 units of strength, is an awakened Observation Haki user, and thanks to the Scythe Fruit's Paramesia, which increases his stealth and attack power, he is as strong as, if not stronger than, Rob Lucci 11 years later. This is the talent I gave to the main character.
However, compared to Luffy, who became one of the Four Emperors at the age of 19, Sonic's growth rate is not as fast.
