Slipknot

 is a Tier 4 Tank that upgrades from Triple Shot and Twin Flank at level 45.

Design
The 's forms look near-identical to its two pre-evolutions. As with most transforming tanks, its forms had transformation indicators which were on each cannon of the 2 forms.

Technical
This tank is able to swap between its two forms on shift. Both forms perform exactly the same as the tank they replicate. The Twin Flank took the blue indicators and the Bent took the red ones(the Bent's red indicators were slightly hot pink).
