Red Slimes (レッドスライム Reddo Suraimu?) are a subspecies of slime. Compared to normal slimes, red slimes are more acidic and volatile, and their bodies contain more digestive juices. They are smaller than standard slimes and have more aggressive personalities, and are known for their acrid behavior and remarks. It is believed that they developed acidic bodies capable of digesting just about anything to adapt to life in environments with little edible matter, such as deserts.
