@Washu, unfortunately, it's prohibited to share links to illegal content on this site, so I can't give you any exact links to Trigun. However, most popular online manga readers (it's easy to google them up) will have Trigun.

<p>In <em>Trigun</em>, Vash the Stampede is able to transform his arm into a big weapon with which he makes a hole in the moon. Is that transformation ever explained? Did he acquire this power after the spaceship crashed or did he have it since the beginning?</p>

How is Vash able to transform his arm into a weapon?
