USMC turned Cyborg. The Cyberines are the next level of military evolution.
Cyberine was in a tragic accident that required the government to make him better, stronger and faster. And it cost a helluva lot more than $6 million dollars.
The Cyberines follow a "family" of Cybernetic Marines. They are the top tier of elite combat class of soldier: the USCC, the United States Cyberine Corps. Their members are recruited and trained at a young age and then cybernetically or genetically enhanced due to an accident or injury that has occurred in the line of duty.
