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.

What will happen to British expats currently working or living abroad when Brexit happens? Will they be able to stay and continue their jobs/lives there?

The United Kingdom's withdrawal from the European Union, commonly known as Brexit, has had a number of impacts on British citizens living and working abroad in EU member states.

One of the main impacts of Brexit has been the introduction of new rules and regulations regarding the rights of British citizens to live and work in EU member states. Prior to Brexit, British citizens had the right to live and work in any EU member state under the principle of free movement, which allowed for the unrestricted movement of people within the EU.

After Brexit, the rights of British citizens to live and work in EU member states are determined by the specific terms of the UK's withdrawal agreement with the EU and the subsequent agreements made between the UK and individual EU member states. In general, British citizens who were living and working in an EU member state prior to the end of the transition period on December 31, 2020 are able to continue living and working in that country under the same conditions as before, provided they meet certain requirements, such as registering with the local authorities.

However, the situation for British citizens who wish to move to an EU member state after Brexit is more complex, as they may be subject to different immigration rules and may need to apply for visas or work permits in order to live and work in the country.

Overall, the impact of Brexit on British expats living and working in EU member states will depend on their specific circumstances and the specific terms of the UK's withdrawal agreement and subsequent agreements with individual EU member states. It is important for British citizens living and working abroad to stay informed about the specific rules and regulations that apply to their situation and to seek advice if necessary.
