Fanon:Original Flash

The Original Flash is a Tier 2 tank that upgrades from Tank at level 15. It looks like the tier 1 tank but with a square instead of a circle, allowing it to be seen as a noob. It may further upgrade into Speedy Shooter, at level 30.

It will shoot is the opposite direction than it is moving to. if you turn on auto fire then it can get top speeds, but will soon ram into the diep.io wall.
