[Inside the Granian Mothership.]
Ace, Cherry, and Jim were directed to one of the many laboratory facilities on the ship to have their symbiotes genetically modified, per Lord Grim's orders. With only one week left until an alleged war broke out, the Granian warrior decided it would be best to subject their walking weapons to a complete procedure designed to make them stronger, quicker, and faster.
Once in the facility, the three Mutants were strapped down and had their backs exposed. The procedure began with robotic arms slowly cutting their flesh open without the use of prosthetics.
The Mutants gritted their teeth and bore through the pain, but that was only the beginning. As the symbiotes sensed a change in their hosts and their bodies, they started to dig deeper into the three humans' backs, causing them immense levels of pain.
