History
In 1879 Kro seemingly lead the Deviants to conquer the surface world and enslaved humanity. 150 years after their conquest Kro helped develop the humans into enhanced mind-controlled gladiators and helped enslave others and eradicate the Eternals and Skrulls. After meeting with Ghaur, Kro visited Tode and Vira to discuss their world and his assassination plans for Ghaur during one of the gladiatorial events. During this time, Kro sent Spider-Man to assinate Ghair but all were interrupted by the arrival of the Silver Surfer.[1]
