Well said I'd do either a Bazooka or a RPG so i went with a bazooka for the sake of simplicity. Borrowed a few idea's form the Gaint Bazooka Doms and Rick-doms lug about one being the side mounted scope and two being the bar just below the barrel. I loved how in the part I saw where that part of the bazooka was used like a club and smashed a Transport (Medea ) shuttle. Other than that it's pretty close to being as practical as it can be.

The shell it would fire is.... well huge not sure how huge but its like... huge. Also considering using a small nuclear warhead that could be used in the bazooka but its still a 'maybe' more than it is a 'yeah.'

Other than that not much else i can say... other than how much I'd love to have a human sized non functioning one of these. <3 Or maybe functional enough to fire water balloons or foam projectiles are unsuspecting victims. -evil grin-
