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.

Living fossils still existing


Living fossils are species that have remained largely unchanged over millions of years and provide a unique link to the distant past. These species have survived mass extinctions and the changing climate, and are considered to be some of the most resilient species on Earth. Some examples of living fossils include:

Coelacanth: This fish is considered to be one of the oldest species on Earth and is a direct ancestor of the first land-dwelling vertebrates.

Horseshoe crab: These ancient arthropods have remained unchanged for over 400 million years and are still found in shallow waters along the Atlantic coast of North America.

Tuatara: This lizard-like reptile is found only in New Zealand and is the only remaining species of its kind.

Nautilus: This ancient cephalopod has remained largely unchanged for over 500 million years and is considered to be one of the most primitive living mollusks.

Ginkgo biloba: This ancient tree species has been unchanged for over 200 million years and is now found in temperate regions all over the world.

These species play an important role in scientific research, helping scientists to better understand the evolution of life on Earth. They are also fascinating to observe, and their resilience and adaptability are a testament to the power of nature and the diversity of life on our planet.
