From her official Filecard:

"Agent Helix is a Covert Operations Officer with advanced martial arts training and expert marksmanship. An Olympic-class gymnast, her distinctive "Whirlwind Attack" is an overpowering combination of kicks and firepower."

The Helix comic one-shot goes on to explain how she is a kind of 'combat savant', where she retains all forms of combat she encounters... truly a worthy recruit for GI Joe!

I struggled with the painting of the figure, trying to decide if I wanted to stay true to 1982 paint masks, or keep adding detail to get closer to the 2009 Agent Helix Figure. I fell somewhere in the middle...

By the way, I am a big fan of this character, and am glad she was added to the mythos!
