11 year-old Joe DeRosa wants to dress up as a girl this Halloween. That girl is Samus Aran, star of the Metroid series. So his dad Tony is helping him build an awesome arm cannon.

This adorable video showcases the construction of the cannon, which with light and sounds (based on the Metroid prime design of the character) is very impressive. The pair also hope to get a completed helmet and chestplate finished by Halloween, too, so can't wait to see what they look like.

You can see more pics at the project's site below, which in a further display of adorability, is entirely in character.
