Katarzooka

Katar: The katar is also commonly known as a 'punching dagge,' basically grabbing the grip with a fist and using it in a similar way to fist fighting, except you can also block and parry more safely. This version has dual blades for maximum damage on a clean blow, and even a small revolver in between the blades for some ranged attacks. (The revolvers weren't there in the original design, but I felt it needed a little more ranged capability, not to mention that gun katars were a real thing) As the revolvers only hold a few rounds each, these rounds are typically dust enhanced in some way to deliver the maximum punch they can. Another key detail is that the Katars also have a lot of metal around the forearms to serve as addition protect and allow for much greater blocking potention in melee combat, not to mention the backs are bladed, just in case I guess.

Bazooka, the sides extend backwards and a tube form the interior push forward as the grips rotate 90 degrees (so that the blades don't dig into your shoulders) then the user loads in powerful rpgs to finish off opponents.

This is a very unforgiving weapon. While potentially extremely damaging, both the revolvers and the bazooka don't have a lot of ammo to spare, so every shot counts when not in melee. Not to mention that it takes a relatively long time to set up the bazooka mode, at which point the user must rely on their teammates, or other various circumstances, to cover them while they're setting up, but once it's complete it can potentially be the most devastating attack in a lot of parties.
