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.

How did people write and draw before the invention of ballpoint pens?

 Before the invention of ballpoint pens, people used a variety of writing and drawing tools to create written and artistic works. Some of the most common writing and drawing tools used before the invention of ballpoint pens include:

Quills: Quills were the most common writing instrument before the invention of ballpoint pens. Quills were made from the feathers of birds, typically geese or turkeys, and were sharpened to a fine point. Quills were used to write on parchment, paper, or other materials, and they could produce a wide range of line widths depending on the pressure applied.

Ink: Ink was used as a writing fluid in conjunction with quills or other writing instruments. Ink was made by mixing water, pigment, and a binder, and it was used to create written works on a variety of surfaces.

Pencils: Pencils were another common writing and drawing tool before the invention of ballpoint pens. Pencils were made from graphite, which was ground into a fine powder and mixed with clay to create a writing implement. Pencils could be used to write or draw on paper or other surfaces, and the line produced could be easily erased.

Fountain pens: Fountain pens were another type of writing instrument that predated ballpoint pens. Fountain pens were filled with ink from a reservoir and used a nib (a pointed tip) to apply the ink to paper or other surfaces. Fountain pens were an improvement over quills because they did not require the constant re-sharpening of the point.

Overall, before the invention of ballpoint pens, people used a variety of writing and drawing tools, such as quills, ink, pencils, and fountain pens, to create written and artistic works.
