Essentially, the Crimson Ant is the same in behavior towards the normal Terror Ant, but classified by both humans and ravagers as its own being. Many of the Terror Ants' abilities and strengths are pushed to extremes in the Crimson Ant: stronger, tougher, and more aggressive like the red subspecies of Hornets. Physically they are "black ants", but with a bright red tint.
As the Crimson Ants are so similar to the Terror Ants in behavior, hierarchy, and abilities, they also have two known mutated variants to them:
- Dark Crimson Ant - These are the more durable counterparts to the Crimson Ants. Although referred to as a Crimson Ant, its skin coloration leans more towards a reddish purple. They are comparable to the Golden Terror Ants.
- Light Green Ants - Although appearing strikingly like a younger counterpart to the Dark Green Ants, these are true variants from the Crimson Ants. They are the smallest and fastest of all ants, too small even to bite and instead ram opponents into the air like bulls.
Unlike the Terror Ant subspecies, these subspecies of Crimson Ants were only used once by the Ravagers during 2025 before both subspecies were discontinued.
