Fanon:Roadgrinder (GellyPop)

"Not to be confused with Roadgrinder Mk. II, another Crasher-based supposedly its successor that takes similar attack methods."The Roadgrinder is an AI-controlled Boss in Diep.io. It primarily uses its Body Damage as its attack method, firing its cannons to push itself.

Design
The Roadgrinder features a large Crasher body, being the same size with the Guardian. It has no front weapons, but on its back, two Machine Gun cannons and a Destroyer beneath those are mounted.

Story
There is no doubt why this Boss is titled as "Brutal Pink, Roadgrinder". Being a much larger Crasher of a kind, it fears nothing when fighting against tanks. It also doesn't give mercy upon those, and so when it spots a pretty bit grown up tank, why wait for it to get stronger by destroying their kind and later on destroy the Roadgrinder too? Unfortunately, the Roadgrinder is rather reckless, and it doesn't mind what it rams into. At least, Trapper tanks doesn't still last long enough upon seeing the large pink shape chasing them until death.

Technical
As suggested by its name and its weapons' locations, the Roadgrinder is a ramming Boss. It generally relies on its massive Body Damage to attack tanks, as it has no frontal ranged capabilities. If not firing its weapons, the Roadgrinder is as slow as the other Bosses. It has 3,000 health.

Both the Destroyer and Machine Gun cannons have the same fire rate with the playable tanks with maxed out Reload. However, bullets that came from the Machine Gun cannons deal the same damage as from the bullets of the Defender's auto turrets. On the other hand, the Destroyer bullets deal 8x the damage. The Roadgrinder never uses the cannons as its primary attack though, so unless the cannons are faced towards a player (which usually happens when the Roadgrinder targets another player), the cannons mainly serve for the Roadgrinder's recoil to improve its speed. Doing so allows the Roadgrinder to attain a speed slightly faster than the Fallen Booster.

Defeating the Roadgrinder awards the player that dealt the killing blow 30,000 XP points.

Strategy
The Roadgrinder acts more like a Fallen Booster. However, since it is a Polygon Boss, it is allied to the Polygons, and so only attacks players. This generally makes the fight difficult.
 * Strong Against: Particularly any tanks with low Movement Speed, Overseer branch, Sniper branch, Smasher branch.
 * Weak Against: Fast tanks that can deal damage while escaping, Tri-Angle branch, Destroyer branch, Trapper branch.

Tri-Angle branch tanks, particularly the Fighter, can be effectively against the Roadgrinder, especially when using a glass cannon type build. However, one must pay attention on where they are going, as bumping into Polygons could slow them, not to mention that they have generally lower health.

If played correctly, Trapper branch tanks can be quite effective. Since the Roadgrinder doesn't actively evade ammunition, a player can lay down traps on the Roadgrinder's path while escaping. Apart from dealing damage, it can slow down the Roadgrinder's speed, increasing the player's chance of survival.

Trivia

 * This is an alternative Boss that may spawn instead of the Guardian.
 * This is another Boss that is based upon Crashers.
 * There is a "successor" of the Roadgrinder, named "Roadgrinder Mk. II".
 * This, however, only has different weapons and attacks, and no actual improvement on its stats.
