Joker

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

Design
The looks similar to the Canasta, but with many more barrels extending outward. This creates a strange, not quite triangular protrusion on the end of its barrel, all seemingly one color due to how closely the barrels are packed together.

Technical
Like the Canasta, the Joker is able to deal critical hits. However its critical hits do 3x the damage of a normal bullet (it is not known how much more damage a Canasta crit does).
