Jinx had served the G.I.Joe team for years, starting as a Rawhide, and later becoming equal in skill and reputation with Snake Eyes. At some point, she was "borrowed" by the CIA for several off-the-books operations.
She had recently gotten married to her long-term boyfriend and fellow member of the G.I. Joe team, Kyle A. Jesso a.k.a Budo. The outbreak began while they were on their Honeymoon in Hawaii. They watched TV news coverage as the first isolated reports of attacks by rabid people began. They had returned stateside and moved into their new home when the first quarantines began. They were on Base when the announcement was given, Zombies were real, and they were attacking with impunity. They served together with honor, going into the heart of battle, relying on their prowess with cold steel, as well as their love for each other.
When the Joe team crumbled, they like many of the members, retreated into the wilds, intending to survive while helping as many people as they could along the way. For years they succeeded in helping those in need of defense. They helped to end horde sieges. They killed ruthless warlords. Then a day came that they couldn't see coming.

I based this on the work of my buddy Hawkeye aka The Pros From Dover. He made a modern tactical Jinx and I liked the idea. I made a few changes so it's not identical but the basic concept was from him. I still want to go back and add the dragon waterslide as well as do some more detail work and possibly add a wash.
