Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Why didn't Chanakya teach Arthashastra to Ashoka?

 Chanakya, also known as Kautilya, was a philosopher, economist, and statesman who is credited with writing the ancient Indian treatise on statecraft, known as the Arthashastra. Ashoka was a monarch of the Maurya dynasty who ruled a large kingdom in ancient India in the 3rd century BCE. It is not clear why Chanakya did not teach the Arthashastra to Ashoka, as there is limited historical information available about their relationship.

There are several possible explanations for why Chanakya may not have taught the Arthashastra to Ashoka. One possibility is that Chanakya may have written the Arthashastra after Ashoka's reign, in which case Ashoka would not have had the opportunity to study the treatise. Another possibility is that Chanakya may have had other priorities or responsibilities that prevented him from teaching the Arthashastra to Ashoka. It is also possible that Ashoka may have had access to the Arthashastra or other teachings from Chanakya through other means, such as through advisors or scholars who were familiar with the treatise.

Overall, the exact reason why Chanakya did not teach the Arthashastra to Ashoka is not known and is a matter of speculation.
