If you could have any video game weapon...

I can't believe after 42 posts no one said the Portal Gun. Isn't that the greatest thing ever? Though I guess it's not technically a weapon.

The portal gun was my second choice. I like the gravity gun better though, because everything not bolted down becomes a weapon.

Does a falcon punch count as a weapon?

Unfortunately not. However, things like Plasmid syringes do count.
