the art style looks too difrent, so it would make no logic or sense, this has a simple industrial design with wires and its box-like (the giant box compartment thing on the side), the cowmangler and the bison have a somewhat toyish design with all the sparkling antenas.

yeey

Actually, it looks like it has the potential to be the cow mangler of the heavy... but it will need serious debuffs to counter the infinite ammo- otherwise heavies would just walk around firing this thing nonstop.

+Has infinite ammo while battery is on
+Can shoot through multiple enemies, each enemy hit the next one hit will do 10% less damage
-When the battery runs out you MUST go back to spawn and resupply or go to a friendly dispencer

+you have 400 ammo
- you goota whait ultil the battery recharges
-no random crits
-you gotta whait 4 minutes ultil the batery recharges or go to a dispencer and wait 2.56 minutes
+has a metter that when it fills gives you a minicrit
-only the vaccinator can uber you
- you taje a minicrit on all hits that you get from enemies
+you can shot trough multipe enemies , each enemy on hit will do 10- damage

It could also be alot simpler:
+Infinite Ammo
- has to cool down, or you have to recharge the battery by cranking some lever, similarly to the cowmangler
