Vash

Vash the Stampede also known as "The Humanoid Typhoon" due to the path of destruction he leaves behind. Vash is the most wanted felon in Gunsmoke; bearing a $$60,000,000,000 sixty billion double dollars bounty. As a result of this bounty the Bernardelli Insurance Society starts following him, two agents were designated for this: Meryl Stryfe and Milly Thompson. An important characteristic of Vash is that he, as well as his brother, Knives aren’t humans they are sentient Plants, an energy source created by humans.

Both Vash and Knives were born and raised on a human ship, Rem Saverem take the task of raising both of them as her sons. She teaches Vash the philosophy that every living being good or bad deserves to live; he takes it to the extreme by always trying to save everyone. Ultimately the ship crashes due to Knives work, starting a conflict between him and Vash.   

Vash acts wacky and exaggerates foolish characteristics to avoid any recognition and to make people feel secure when his around. He shows an almost obsessive love for donuts. Whenever someone around him are in danger he changes and becomes completely focus and serious. Vash refuses to kill any of his opponents; which leads him to suffer at the hands his enemies. The abuses made by his enemies are clearly evidenced by his body; a mess of large scars, chunks of missing flesh supported by metal mesh, and stitch marks.
