Trilobite

Trilobites are an ancient type of Virus that appeared in Rockman.EXE Stream. They are large, brown beetle-like creatures with three red eyes. Their shell is very hard. They appeared in a space-time distortion that was caused by a meteor, and easily overpowered the Cross Fused Rockman.EXE and Blues.EXE before Colonel.EXE saved them. 20 years before the events of Stream, some Trilobites were summoned by Jackass to buy time to withdraw his safe-cracking pillars while Colonel was stopping Jackass from stealing Amerope's military data. ​
