Viruloids are foot-long prokaryotic cells. They have pink cytoplasms, glowing white cilia at the “backs” of their bodies, and black eye-like organelles at the “front.” Despite being half the size of nucleoids, viruloids are their natural predators. Viruloids will also eat just about anything that gets in their way, unless they stand no chance of defeating it. They take a more hasty approach to attacking than nucleoids, sending their lysosomes at a victim the instant they make contact.
