Pumper

 is a Tier 5 Tank that upgrades from Annihilator and Bumper at level 60.

Design
The has a similar barrel to Bumper, but slightly wider. Its decorative trapezoid inside the barrel is also made slightly wider, now looking to be the same width as the main barrel.

Technical
Like Bumper, the fires bulky missiles with a large propulsion barrel. Compared to Bumper, its missiles are slightly larger and their propulsion barrels are even wider than Bumper's. They seem to have more recoil too but fire slightly slower to compensate, essentially being Destroyer versions of Launcher propulsion barrels.
