Crazy Ants

A highly aggressive giant creature, quicker and more ferocious than the Storm Ant.It can also spit acid in multiple directions.
These creatures first emerged in South America, and were originally engaged by the forces of the South American EDF branch, but after it was observed that they prey upon other giant creatures, the EDF considered a plan to use them tactically in combat.
However, the plan backfired, instead encouraging the Crazy Ants to reproduce at an abnormally rapid speed, leading to the demise of EDF South America.
These creatures have since migrated North, and are swiftly expanding their territory along with the Storm Ants.
