That looks like a Bolt zombie! Medic has been dying to cut into one of those!
Hmm… Maybe when she's done, I could use a hydraulic press and shove it into a battery.

Description

The Bolt is a very fast enemy that appears in Intermediate mode and Challenge Trials. It is noticeably faster than most of the enemies that have spawned previously, or will subsequently, in Easy mode. It also has slightly more health than the Armored, though it lacks its defense.

In Casual mode, the Grave Digger can spawn the Bolt with its Summon ability. The Bolt can also be spawned from the Mystery upon its death in Easy mode.

The Bolt is replaced by the Arrow in Headache Headquarters.

Appearance

ModernLegacy

CurrentVersion 1

The current Bolt has a glowing bright yellow skin color and a desaturated yellow torso and legs. It wears a grey vest on its body with a glowing yellow lightning bolt emblem and a yellow stripe going down the middle. The front side of the vest has smaller yellow stripes leading up towards the backside. The backside of the vest has an exposed compartment with a red switch and two batteries labeled "Durablox" embedded into a battery compartment. It also has two vents on the backside that emit a yellow aura. It constantly emits sparking particles.

It plays a thunder striking sound on death.

The first version of the Bolt had glowing bright yellow skin and a dark yellow torso and legs. It had an energy pack on its back, a glowing desaturated yellow lightning bolt on its chest and desaturated yellow veins could be seen on its body. It also emitted yellow particles as it runs.

CurrentVersion 2Version 1

The current version of the legacy Bolt is smaller than most of the enemies in the game. It has neon sky blue skin, and a diamond-plated torso and legs. There is a blue lightning bolt symbol on its torso and it wears grey diamond-plated armbands. When it runs, it has a sprinting animation. Blue sparks come out from its torso and arms.

It played a popping sound on death.

The second version of the legacy Bolt was identical to its third version, except it had a sad face.

The first version of legacy Bolt had neon blue skin, a dark grey torso and legs with a lightning bolt symbol on its torso. It also wore grey diamond-plated armbands. Blue sparks were emitted from its head. When running, its animation was similar to that of a Naruto Run.

Strategy

• Early game towers like the Soldier, Militant, Biologist, Assassin or Cowboy can be used to deal with this quite well.
  • DPS towers like the Minigunner, Hunter or Crook Boss can also be effective, though they are not necessary.
• Stalling towers like the Freezer, Electroshocker, Brawler or Warden can be used to stall the Bolt.
  • Do note that most of such towers deal enough DPS to be able to also clear out Bolts on their own.
• Bolts mostly appear in groups, so splash damage towers like the Rocketeer and Mortar are fairly effective.

  • The Bolt and Shock also used to be very similar in appearance with only material and color changes separating them.
• The Bolt was formerly one of the smallest enemies in the game.
• The word "Durablox" written on the batteries is a portmanteau of Duracell, which is a real-life battery brand, and Roblox.
