Pylon Imp

Pylon Imp is a Rare variant of the Imp in Plants vs. Zombies: Garden Warfare 2. T​he Pylon Imp wears a cone on his head. His Z-Mech is a large robotic cone mech with one wheel, and it is faster than the typical Z-Mech but has the trade off of having 50 less HP. The Pylon Imp was first teased in the Aloe 5: Gardening spoof, but was later shown in the Multiplayer Beta trailer, before being shown in short gameplay of the Backyard Battleground. He and the Z7 Imp are the only unlockable Imp variants in the beta.

Imp
The Imp's primary weapon are the Pylon Punishers. The Pylon Punishers has a trade off in ammo and attack speed, however this makes up for its small splash damage. It can fire up to 32 shots in two-shot bursts before reloading.

Pylon Mech
The Pylon Mech's primary weapon is the Pylon Propellor. Like Pylon Imp, it does splash damage but it has half the ammo of a Pylon Imp. The Pylon Mech is equipped with proximity Pylon Mines, the Pylon Propel melee attack, and the standard Explosive Escape.

Trivia

 * This could possibly be inspired by the Robo-Cone Zombie in Plants vs. Zombies 2.
 * This may be a reference to real-world drag racers, due to its increased speed and the exhaust pipes that occasiaonally combust.
 * The Pylon Mech's health was nerfed from 350 to 300, due to the nerf of the basic Imp's Z-Mech, which was from 400 to 350.
