Kilonova

 is a Tier 5 Tank that upgrades from Proton at level 60.

Design
The has the same barrel as Proton but its ring loses one shield orb. It now only has two on opposite ends, like how Revolutionist's turrets are oriented. The shield orbs become a deep blue, similar to Flamegun's decorative color or the color of its bullets. It also gains a similarly colored circular decoration on top of its body.

Technical
While its shields and barrel act as expected, its top blue sphere indicates a special ability. Like the Splatterer or Overflow, it can produce a high-velocity 360 degree ring of bullets upon right click. However, these are not normal bullets. They are the same deep blue color as the tank's shields and decoration, and cannot deal damage. Instead, they seem to act like shields, pushing anything they hit away and deflecting bullets.
