Origins
Mr. Toxic is loosely based on the Build-a-Bot with the same name in PvZ:GW2.

With
This zombie, although a little weak, can reduce the threat high-strength plants such as Atomic Bombegranate. Combined with Landscaper, he can reduce plants such as Kernel Corn to the point where they are susceptible to Rolling Stone, Celestial Custodian, or Weed Spray. Because it is in the Machine class, it can get buffs from Screwdriver Wielder and Disassembler.

Against
Stat-wise, this zombie is not threatening and can be removed with Whack-A-Zombie or other instant-kills. However, it will lower the strength of your plants, making them useless or able to be Rolling Stone'd or Weed Sprayed. One way to deal with it is to put a Wall-nut in front of the plant you want to protect, as the Wall-nut has no strength to lose. However, your opponent could easily destroy that Wall-nut with the aforementioned tricks.
