While PRIMUS’ Project Greenskin is working to understand and ultimately contain the threat of the mutated monster known as Grond, VIPER is trying manufacture more of these genetic monstrosities. Project Stein, led by one of VIPER’s lead scientists, Dr. Timothy Blank, is devoted to making a radioactive serum that will create super-strong but slightly more intelligent Grond-like creations, ones that will be loyal to VIPER. Once Blank’s serum is perfected, it will be loaded into missiles and launched across the world, where explosive fallout will send a radioactive bacterial agent into the atmosphere-- and create an VIPER-controlled army of Gronds!
