Cortex Commandos

The Cortex Commandos were an army of genetically engineered animals led by the evil and diabolical scientist Neo Cortex during the Mutant Vortex Crisis. The formation of the army is a historically significant event as it marked the beginning of the abominable technology of genetic engineering. The army was manufactured in the Cortex Castle complex on Cortex Island. Many of the animals were constructed in horrific facilities and the engineering has been considered a crime against God.
